The first production gated systems (including the BGP4 protocol) were installed on the RS/6000 based routers that support the T1 trans-atlantic link (CERN - MAE-East). An extended fiber outage occurred in Michigan on December 3rd due to a fiber cut. December Backbone Traffic and Routing Statistics ================================================ The total inbound packet count for the T3 network (measured using SNMP interface counters) was 46,029,222,164 on T3 ENSS interfaces, up 3.0% from November. The total packet count into the network including all ENSS serial interfaces was 52,282,909,913 down 1.1% from November. The maximum number of destinations announced to the T3 network during December was 14,802, up 6.6% from November. The number of network destinations configured for announcement to the T3 network but were never announced (silent nets) during November was 4,978. T3 Network Upgrade Progress/Status ================================== On December 18th, we successfully completed the Phase 5 ANSNet deployment. The major changes accomplished in this upgrade were: o Upgrade of all DS3/HSSI router serial interface adapters (T3 CNSS and ENSS) to support full DS3 bandwidth. The router adapter bus interface cards were also upgraded to double the packet switching rates per interface. o The T3 DSUs on each DS3 interface were replaced with T3Plus BMX45 bandwidth managers on T3 CNSS-CNSS circuits and Larscom Access-T45 DSUs on a T3 ENSS-CNSS circuit. o The architecture for interconnection among CNSS routers at each MCI POP location was upgraded to a common FDDI ring from the original point-to-point links architecture. Cooper [Page 8] Internet Monthly Report December 1993 As a result of this upgrade, we now have 17 backbone links and 21 customer attachments running at full T3: Seattle - Denver Backbone Link Seattle - San Francisco Backbone Link San Francisco - Chicago Backbone Link San Francisco - Los Angeles Backbone Link Los-Angeles - Albuquerque Backbone Link Albuquerque - Houston Backbone Link Houston - Atlanta Backbone Link Atlanta - Greensboro Backbone Link Wash DC - Greensboro Backbone Link New York - Wash DC Backbone Link Houston - St. Louis Backbone Link Denver - St. Louis Backbone Link St. Louis - Chicago Backbone Link Chicago - Cleveland Backbone Link Cleveland - New York Backbone Link Hartford - Cleveland Backbone Link New York - Hartford Backbone Link ENSS128 at Palo Alto (BARRnet, Stanford University) ENSS129 at Champaign (UIUC, CICnet) ENSS130 at Argonne (Argonne National Lab, CICNet) ENSS131 at Ann Arbor (ANS AA, Michnet, CICnet, etc.) ENSS132 at Pittsburgh (PSCnet, PREPnet, CMU, etc.). ENSS133 at Ithaca (PSI, Cornell) ENSS134 at Cambridge (NEARnet, Alternet, MIT) ENSS135 at San Diego (CERFnet, SDSC, etc.) ENSS136 at College Park (SURAnet, Alternet, MAE-East, UM) ENSS137 at Princeton (Princeton University, JVNCnet) ENSS138 at Atlanta (Georgia Tech, SURAnet) ENSS139 at Houston (Sesquinet, Rice University) ENSS140 at Lincoln (MIDnet, Westnet, etc.) ENSS141 at Boulder (Westnet, NCAR, U of Colorado, etc.) ENSS142 at Salt Lake City (WestNet, U of Utah, etc.) ENSS143 at Seattle (NorthWestNet, U of Washington, etc.) ENSS144 at Moffett Field (FIX-West) ENSS145 at College Park (FIX-East) ENSS146 at Arlington (ARPA) ENSS172 at Albuquerque (Phillips Laboratory) ENSS179 at Albuquerque (Sandia National Labs) Rcp_routed Routing Software Changes =================================== Toward the end of November rcp_routed began experiencing problems where system paging slowed down rcp_routed causing it to allocate memory to defer work, which in turn causes more paging. Several Cooper [Page 9] Internet Monthly Report December 1993 new rcp_routed versions were deployed on ENSS136 to reduce the memory requirements. Problems on ENSS136 have been eliminated by adding more memory and rcp_routed changes to avoid triggering the condition. Release notes are available for anonymous ftp at: ftp.ans.net:/pub/info/t3-rcp_routed/Release-Notes. Routing Stability Measured on the T3 Network ============================================ Internal routing stability measurements are made by monitoring short term disconnect times (disconnects of five minutes duration or less). This is intended as a measure of stability rather than complete connectivity. December stability dropped to levels observed in July and August due to problems with rcp_routed, and phase-5 scheduled outages. MONTH overall excluding configs ------ ------- ----------------- January 99.1% 99.5% February 99.0% 99.5% March 97.5% 99.1% April 96.1% 97.2% May 97.4% 98.0% June 95.5% 96.6% July 97.3% 97.7% August 97.5% 97.9% September 98.1% 98.5% October 98.0% 98.3% November 97.2% N/A December 96.6% N/A Due primarily to paging problems, few nodes experienced less than 30 minutes of instability for the month. Significant perturbations such as the phase 5 activity on Dec 4, Dec 11, and Dec 18 caused paging elsewhere and secondary instability. On a few occasions core circuit link state changes triggered problems. ENSS136 was the most affected node, though also affected were ENSS135, CNSS11, CNSS65, ENSS139, ENSS131, and to a lesser extent others. There were also the usual site power problems. The breakdown by sites is as follows (these figures include instabilities recorded during configuration runs): Cooper [Page 10] Internet Monthly Report December 1993 MONTH >5 hr >2 hr > 1hr >30 min >15 min <= 15min <98.7% <99.7% <99.87% <99.93% <99.97% >=99.97% ------------------------------------------------------------ January 0 0 1 8 19 55 February 0 0 1 24 19 41 March 0 4 18 23 23 22 April 2 2 3 13 12 57 May 0 4 33 32 15 5 June 3 21 35 18 12 3 July 0 12 28 44 6 1 August 1 5 28 21 17 15 September 1 38 25 10 4 13 October 0 3 3 10 25 50 November 1 2 15 25 24 26 December 0 8 24 46 9 3 There has been steady increase in the external route flap over the course of the year. The measurement method is described in: ftp.ans.net:/pub/info/routing-stats/ExternalRouteFlapReports The number of times networks are announced as unreachable is collected. The following represents the monthly totals in terms of number of networks declared unreachable per hour. January 844 May 1134 September 2395 February 876 June 1560 October 2272 March 1104 July 1815 November 2321 April 1038 August 1874 December 2008 Plots of the internal routing stability, external peer session stability and external route flap are available as the files: ftp.ans.net:/pub/info/routing-stats/internal.ps ftp.ans.net:/pub/info/routing-stats/external.ps ftp.ans.net:/pub/info/routing-stats/flap.ps A slight reduction in the external route flap in December, and a clear reduction in the size of route flap peaks is believed to be at least partly due to limited fixed timer based route dampening at the ENSSs. The data itself is collected at a CNSS and so reflects the flap after dampening by the ENSS and reflects the load redistributed to AS 690 peers taking full routing. External peer stability data in December was dominated by the RIPE RS peer. This peer is experimental and does not introduce any routes to AS 690. It is a gated peer and has a configuration that Cooper [Page 11] Internet Monthly Report December 1993 has now grown in terms of route restrictions to the point where gated is unable to remain stable in the presence of route flap. Changes to gated to address this are expected to be deployed soon. This peer and the ANS experimental gated peers will be removed from the raw data in future reports. Gated BGP4/CIDR Deployment Update ================================= ANS has been working to meet the proposed BGP4 deployment schedule. We have participated on the BGP4 testbed, and in early December we deployed gated with BGP4 on the production AS1133 routers (DANTE/ANS service between CERN and MAE-East). We continue to test gated with SLSP (AS690 IGP) support on the NSFNET/ANSnet testbed. We have had some problems with the Gated SLSP IGP protocol code due to performance enhancements that were made in the Gated base code that has been successfully deployed on the AS1133 routers. Since overall network stability is the major goal, we have not yet begun deployment of Gated on the AS690 routers. This version of Gated is designed to interoperate with the rcp_routed software (the IGP and internal BGP). The SLSP support in Gated allows us to deploy Gated without an IGP "flag day" on AS690 routers. We expect to get Gated fully deployed on ANSNET/NSFNET routers in time for a CIDR transition (class-based routes stop getting announced) in mid-February. We are exploring two contingency plan options to provide continued full connectivity in the event that other backbones cease announcing class-based routes via BGP4 and announce only the aggregates. The first option is to have the AS690 routers point default to our AS1133 router at MAE-East, which supports BGP4 now. Since Rcp_routed (current AS690 routing software) has never supported default, this is being added and tested, and should be ready in time. The second contingency plan option we are exploring is to establish BGP4 peering sessions between AS 1133 and other BGP4 capable systems at MAE-East. AS 1133 could accept aggregate announcements from its BGP4 peers and be configured to announce the class-based routes within the aggregates to AS 690. Either of these contingency options could serve as an interim step while AS 690 completes deployment of gated. We hope that it will be unnecessary to resort to any contingency plan, but realize that some ASs are faced with overwhelming loads on their routers and that those AS may have to begin to only announce aggregates rather than the dual announcements of aggregates and class-based routes by the mid-February timeframe. Cooper [Page 12] Internet Monthly Report December 1993 Notable Outages in December '93 =============================== E131 (Ann Arbor) suffered an extended outage due to fiber cut on 12/03 (see details below). E257 (Creative Cybernetics) suffered an extended power outage on 12/04 E129 (Champaign), E140 (Lincoln) and E138 (Lincoln) underwent Phase V upgrade on 12/04 E131 (Ann Arbor), E132 (Pittsburgh), E137 (Princeton) underwent Phase V upgrade on 12/11 E133 (Ithaca), E134 (Boston), E136 (College Park), E145 (Fix-East), E146 (ARPA) underwent Phase V upgrade on 12/18 E257 (Creative Cybernetics) suffered extended downtime due to circuit maintenance on 12/22 E179 (Sandia Labs) suffered extended downtime for maintenance on 12/27 Michigan Fiber Cut (12/3): ------------------------- A fiber cut occurred in Michigan on 12/03 fiber due to a contractor backhoe. This affected 87 MCI DS3's. The outage lasted from 11:45 to 17:25 EST for a total of 5 hours and 40 minutes downtime. While the Network Operations Center in Ann Arbor was isolated from the national network, network monitoring continued from the ANS backup NOC in Elmsford. There was some blockage of calls to the 1-800 number due to reduced capacity into the Michigan area. To avoid future outages of a similar nature, MCI has implemented a T1 restoration capability that will be coincident with their signalling restoration process. Presently this requires manual intervention, but should only take a few minutes to implement. A full automated restoration capability will be in-place by mid July 1994. Jordan Becker, ANS (becker@ans.net) Cooper [Page 13] Internet Monthly Report December 1993 ILAN - ISRAELI NETWORK ----------------------- ILAN is currently in the final acceptance stages of a 256kb satellite line to PSI to replace our existing 128kb. We still maintain a 64kb fiber line to Europe. On a national scale, ILAN has outgrown its 128kb leased line backbone and has signed an agreement with the national PTT to be the first customer to use its MAN service. The seven university backbone will run on 10Mb/sec Ethernet speeds via the MAN service (the only service offered by our PTT - no SMDS yet). The first two sites are expected to be operational in February 1994, with one site following every month thereafter.

It allows a caller to explictly invite others to participate in a point-to-point or multipoint teleconference, and alerts them to accept or decline. It automatically spawns underlying audio, video and groupware programs among members of a session, then tears them down at session completion. Cooper [Page 22] Internet Monthly Report December 1993 Mmcc has now been ported run on SGIs running IRIX, HPs running HPUX, IBM PCs running Mach3.0, Dec 5000's running Ultrix V4.3, and Dec Alphas running OSF. The release software will be available from ftp.isi.edu:confctrl/mmcc, as files mmcc-{sparc,sgi,dec5k,decalpha,intel,hp}.tar.Z. The ports have been tested more thoroughly on some configurations than others. Feedback would be welcomed.

Whirlpool will initially have a 9.6Kbps direct dial-up line through Andrews University. The Albion College proposal to the National Science Foundation for Connections grant funding was approved, and work on a 56Kbps link to the MichNet backbone has begun. Grand Rapids Baptist College, an institution of Christian higher education serving over 1,000 students from more than 20 states and eight countries, will also have a 56Kbps link to MichNet. Activity to upgrade MichNet links from 56Kbps to T1 at both the University of Michigan's Dearborn campus and Eastern Michigan University is also underway. Michigan's Governor John Engler has signed Executive Orders entitled "Michigan Council on Telecommunications Services for Public Education," which address the need for educational telecommunications projects that will promote the development of integrated educational telecommunications networks, distance learning, video conferencing and data networks, and make such distance learning technologies available to Michigan students, educators, governmental agencies, health providers, and businesses. The funding for this state-wide distance learning initiative totals $23,230,000, plus interest, and resulted from a Michigan Public Service Commission order that Michigan Bell Telephone Company either refund $10.5 million of its ratepayers' shareable earnings plus interest, or match that sum with a voluntary contribution of $10.5 million and the sum total would be used to fund educational telecommunications projects. The Commission found that such a settlement agreement was in the public interest, and will provide significant funds for such educational telecommunications projects. Cooper [Page 23] Internet Monthly Report December 1993 Dana Sitzler, coordinator of MichNet's K-12 Outreach projects, gave a hands-on demonstration of Internet tools and resources at the Michigan Education Association December conference in Dearborn.

Cooper [Page 27] Internet Monthly Report December 1993 SURFNET ------- THE DIGITAL CITY (DE DIGITALE STAD) Amsterdam, Netherlands 3 January 1994 THE DIGITAL CITY In the Netherlands on the 15th of January 1994 a new city will be born, a digital city. This digital city can be visited by compu- ter and modem, and is connected to the worldwide computernetwork called Internet. The Digital City is an initiative of Cultural Center The Balie and Hacktic Netwerk and is supported by the city of Amsterdam. The aim of the Digital City is to investigate the possible contribution of (data)communication to debates about the future of the city. The project runs from the 15th of January 1994 till the end of March and covers the period, in which local elections will be held in Amsterdam. The Digital City can be reached on phone number +31-20-6225222 (by modem); access is free, apart from the normal telephone costs. Internet address: telnet dds.hacktic.nl Public terminals Visitors can call in by their own computer, but there will also be a few public terminals in Amsterdam, from where you can reach the Digital City. These terminals will be placed in the city hall, the public library, the Amsterdam Medical Centre, De Balie, the Stedelijk Museum and other locations. Internet The Digital City explores a new territory for the Netherlands, while at the same time it is using the knowledge and experience which have been gathered in the United States during the past ten years. At the present moment there are some 15 million users of the Internet, among which most Dutch universities. The Digital City is constructed along the lines of the so-called 'Freenet- systems' that exist in the U.S. These are free information servi- ces, which give citizens access to various networkfacilities. Cooper [Page 28] Internet Monthly Report December 1993 The Amsterdam city hall 'on line' The Amsterdam city hall will be part of the network. Administra- tive information of the city council will be accessible in the Digital City. Various members of the city council and other political representatives will participate in the discussions which will take place in the Digital City. In the Digital City all parties will have their own offices, from where they can distribute their election programmes, positions on current issues and other information in digital form. Participation in electronic discussions In the Digital City the visitor can also join discussion groups, apart from looking through digital archives. Discussions will be held about Schiphol (the Amsterdam airport), cultural issues, building and breaking in the city, the elections, income poli- tics, etc. Exploring the Internet Visitors can explore the Internet. Whether you are interested in libraries in Japan or in Finland, or in paying a visit to the White House, or in the latest NASA-information: you just have to hit a few keys on your computer and you can travel around the world. Visitors can become builders The Digital City offers organisations and individuals the oppor- tunity to develop new territories. The citizens can react, bring in new ideas and propose changes. The Digital City will partly be built in cooperation with its residents and visitors. Information brochure In the second week of January 1994 an extensive information brochure will appear. Apart from that there will be a Dutch manual for the Digital City and a 'helpdesk' where you can ask questions during the project. Other activities / Smart TV Various activities will take place in the orbit of the project. Smart TV will broadcast four programmes on the local television channel of Salto (on the 15th of January, the 5th and the 26th of February and the 26th of March 1994), which will deal with the developments surrounding the new information technologies. On the 26th of March 1994 a symposium will be held in De Balie. Cooper [Page 29] Internet Monthly Report December 1993 Thanks The Digital City was made possible by (among others) the city of Amsterdam, the NLnet Foundation, Tornado Modems and Dataman. Technical data The Digital City will be run at Hacktic Netwerk on a Solair 10/30 with 4.8 GB of diskvolume. 12 Tornado HighSpeed modems are connected to it through a terminalserver. The Solair is running Solaris 1.1 Unix with FreeNet software on it. A Gopher-client is used for the connection with the Internet, which is made possible by the NLnet Foundation. The modems are lent out for the period of the project by Tornado.

Although international bandwidth is still insuffiient for really good quality conferences, the feasiability was shown clearly enough, and the plans for 34Mbps and better IP and ATM connectivity will be boosted by such demonstrations. A simple tool for monitoring mbone quality for continuous media traffic was made available to the Internet community for trials. Further tools are very near completion and will be released early in the new year.

Reynolds USC/Information Sciences Institute 1. EARN's Network Services Conference 1.1 User Support Session 1 1.1.1 David Hartland, University of Newcastle Upon Tyne "Sowing the Networking Seed: The Gardener's Experience" The networking world is continuing to grow at a fast rate and there are still a large number of disciplines in the academic and research community which have yet to discover and benefit from them. The User Support Activities of the Networked Information Services Project (NISP) intends to plant the seeds of computer networking in some of these disciplines and nurture the seeds to Cooper [Page 31] Internet Monthly Report December 1993 grow. One of NISP's goals is to support and encourage common training materials. One way NISP is accomplishing this is to globally search for other materials to incorporate into their materials. Many groups experience frustration when the tools don't work or aren't available. It is the user support groups' responsibility to assist in finding the right sources. Some common problems NISP has encountered is that computer literacy isn't, at times, on the highest level. Additionally, some sites have poor or very poor connectivity. Lack of documentation is another problem, along with support people having the lack of time to produce documentation. One suggestion to this dilemma is that target groups should be encouraged to use mailbase services at all different stages and at all levels. The social sciences field is the best group to work with, as they have reference cards, documentation, networked information office postings, and work closely with the NISP. The librarian community has the initial contact with JANET (Joint Academic Network). JANET is an organized, central group that concentrates on the training aspect. JANET also has joint activities with NISP. The higher education administration is the group that is the hardest to get started, basically because there are lots of suspicions to overcome in this community. Security aspects are what they are most concerned about. The key features of NISP is that they do have limited resources, the mailbase factor, and liase with other national projects in the UK. The key factors in working with groups in other disciplines are: first contact focal point publicity training and support The passport to success includes: good connectivity geographically spread the need to communicate coordinated group funding getting key people involved enthusiasm and persistence Cooper [Page 32] Internet Monthly Report December 1993 1.1.2 Margaret Issacs - University of Newcastle Upon Tyne "Issues in Training Users to Use the Network" Issues in training users to use the network and general issues in network training was the format of this talk, with specific reference to the work of the UK Network Training Materials Project, which is developing a generic mix and match set of network training materials for users in UK universities. The general issues include the increase in demand for training, various user requirements, the hazards of being on-line, and the effectiveness of training. There is an enormous widening spectrum of users as the network grows. The expectations of users are rising along with the volatility of network service, as there are constant changes. The network trainer needs to address this issue as well as the continuous upgrades of hardware and software. The main hazard of going on-line is that many things can go wrong, including the network, remote services, and local conditions. In the effectiveness of training, a lot of resources and investment and the increase of community awareness make it effective. Within the Network Training Materials Project is the Informational Technology Training Initiative (ITTI). In the UK context, the initiative's intent is to stimulate the use of computers, computing, teaching and training, and increased requirements and demands. For example, The JANET IP services have come on-line, and dominates its use with Telnet, FTP, Gopher, WWW, etc. In addressing the issues, the scope is to optimize the investment in network training by looking at the training materials that are already developed in the international community, to seek out community input, and then pooling this material. The ITTI team seeks community input and feedback, and shares the information. Generic network training materials are used extensively by trainers at local sites. The materials have a copyright, specifically for non-commercial users. The pooling of on-line materials is obtained via anonymous FTP. In regards to dealing with volatility issues, it is most important to keep current through mailing lists, conferences, and to help to keep the trainers up to date. Coping with on-line hazards requires testing, testing, testing! (Included in the effectiveness is to get feedback from users.) Always evaluate! In summary, there is an increased demand for training and centralized production of training materials. Cooper [Page 33] Internet Monthly Report December 1993 1.1.3 Daniele Bovio - EARN "The EARN Help Desk: A Pilot in International End User Support" NETHELP is an international net-consulting Help Desk service accessible via email for user support personnel and end-users alike. This service is available to EARN (European and Academic Research Network) members. The NETHELP services filters users, creates tickets, ACKs receipts, and handles "help" mailings. There is a Network Consultation Team (NCT) that is made up of four consultants (IT, BE, HU, US). Five people are on staff that work through LISTSERV and handle questions. The result is that NETHELP fielded 200 tickets from 25 countries. All were received and all were answered. Quality of service is stressed in this endeavor. Each query was always answered with a dated receipt, and there was never an answer of, "we don't know the answer". 95% of the global queries were answered on the same weekday. Most questions were fielded from Romania and Russia, as the large majority of ticket work came from countries that are still organizing their countries. The most frequently asked question was, "How do I get this person's email address?". A program called, "trickle" allows you to receive information about PC software. Trickle was the most frequently used program, and had the most queries in this pilot, as the EARN members have the largest ratio of PCs. In addition, many users do not have full Internet access, just email services. The results of this pilot was that this service did not take off in advanced countries, as it was not advertised as much. The countries who had local help services available felt that the EARN's NETHELP service was competition. There was also a language problem from country to country, as EARN's official language is English. The service was quite popular in countries that didn't have local help desks. The main conclusion is that this service needs advertisement. EARN published a leaflet that was available at this conference that explained about NETHELP and what it is. 1.2 Directory Services Session 1.2.1 Erik Huizer - SURFnet "Before We Deliver Directory Services to the End-User..." Implementations of X.500 are hard to find, but they are out there. What are the current issues? Cooper [Page 34] Internet Monthly Report December 1993 Technical Issues fine tuning the standard profiling of the standard interworking security Political-Economical Issues multiple services providers multiple sources for Directory entries how to make money out of Directory services does every organization want a Directory Service? Organizational Issues how do you fill the directory how do you update the directory how do you ensure the quality of the database synchronizing directories replacing existing directories security - access control Legal Issues dataprotection laws privacy laws security (encryption) User Issues - What Users Want reliability quality of data consistency performance integration a) of user interfaces b) with information servers Training/Education Documentation Solutions Paradise Pilots National Pilots Central Directory System Agents (DSA) pilots Operational Agreements Services Level Agreements Performance Studies IETF/RARE WGs Listening to Pilot Users Cooper [Page 35] Internet Monthly Report December 1993 1.2.2 David Goodman - University College London "Paradise in Transition" X.500 towards a global directory...is this a dream or reality? Can it be done? The Paradise Project shows the foundation can be done, but will the end result of X.500's intent be seen in our lifetime? Do we really want it? Or, does it smack of Orwell's "1984"? In the last 26 months, COSINE has provided the funding for the Paradise Project. The criteria for success was the X.500 pilots and a market for X.500 products. This has not yet been satisfied. Another project is needed, including a transition phase which would include: continuation of control services enhancement interworking testing international coordination transition - DANTE to take control of coordination external liaisons The role of the "Giant Tortoise" DSA sits on the Directory Tree Running two DSAs Act as a registration authority The use of Quipu - 95% of DSAs use Quipu Profile of Paradise A White Pages Listing - a listing of organizations and people and who are in them Predominately academic and research (20% commercial) Different restrictions in each country One first level DSA per country Limited guidelines - problems of user expectations and difficulty in enforcing guidelines Statistics In 1990, there were 9 experimental pilots. There are now 26 pilots. There is a fairly complete picture of national pilots in Western and Central Europe. There is a world directory with 47 pilots, with the US being the largest. There are 600 interconnected Directory Services worldwide. 50% in Europe and 20% in the US. The rest is scattered throughout the world. Cooper [Page 36] Internet Monthly Report December 1993 X.500 in the Paradise Project Demonstrates: X.500 works There will be a next year continuation of Paradise Coordination by research networks Focused user oriented guidelines Quality control of the Directory Guidelines need to be given Look at diverse application of X.500 Yellow Pages Security certification authorities A European Directory Forum has been established. Therefore, a global directory is both a dream and a reality. The technology exists, but there are still lots of problems. Vendors are slow to respond. It will take a five to ten year timeframe to provide a coherent directory. This is due to cultural, not technical problems. There was a question from Rolf Nordhagen (NO) about the differences between X.500, WHOIS and WHOIS++. David responded that the two protocols haven't met face to face yet, but that there will be a confrontation eventually. X.500 is slow to come around, and WHOIS was not considered competitive until about a year ago. 1.3 Network for Schools Session 1.3.1 Panel Session - "Internet School Networking: A Global Perspective" Unfortunately, three of the four slated panelists were not at the conference. 1.3.2 European School Project - Henk Sigre The European School Project (ESP) is a support system for secondary schools to explore application of educational telematics. ESP wanted to use the network to enhance education, and started with this project. The project started in 1989 with two schools, one in Amsterdam and another in a small town in British Columbia, Canada. The two schools were connected to communicate about their schools. Both schools are totally different in their environments. The network connection was not just made for the benefit of the students to just chat about the weather, etc. "Teletrips" were developed in this program. Before a Teletrip could begin, the teachers would communicate with each other over the network about the agenda for each Teletrip session. These Teletrips were also Cooper [Page 37] Internet Monthly Report December 1993 conducted in different foreign languages. Teletrips Subjects Included: educational projects local research conversation topics exchange of results foreign language electronic mail Teletrip Examples Included: show your portrait remembering humor-different or... a teenager in... holidays traditions the image of the other everyday life literature school and spare time everyday statistics chemistry school newspaper astronomy school and home life The Implementation of ESP Included: Organizational Teacher Meetings Country Coordinators RISC (Resource Information and Support Center) Survival Teacher meetings were initiated in 1988, with 5 people participating. A teacher's meeting was held in 1993 in Germany, with an attendance of 105 people. RISC supplies the following: inventory - projects, schools, projects/proposals support - supply and demand, techniques acquisition - schools, countries information - newsletters, flyers, information packets, and publications School Environment Data Communication Computer Equipment Restrictions in curriculum, language, time Cooper [Page 38] Internet Monthly Report December 1993 Technical Implementations Included: Focus on email processing Using the Internet File Storage Local Resources Mail Front Ends Technical Support (Technical support is very difficult. This type of support is needed in schools to help teachers with data communication.) Technical Problems Included: Non-ASCII Characters Technocentric User Interfaces Computer Equipment Restricted Format of Messages Data Communication Reliability of the Connection In summary, remember to be flexible and not afraid to change things. George Brett (US) mentioned in this session that in the United States there is an effort underway called, "The Global Schoolhouse", and that he was willing to discuss this project off-line with the session attendees. 1.3.3 Lee Caldwell (US) from Novell provided a demonstration of the use of the Internet in school networking. 1.4 User Support Session 2 1.4.1 Robert Cailliau - CERN "World Wide Web (WWW)" Robert demonstrated WWW at various sites around the globe. From Honolulu to Chicago he showed how easy it was to go around the world using WWW. WWW is a general hypertext model, with the ability to search. Robert used the Honolulu Community College site as an example. The architecture of WWW is that it splits the servers from the clients. The travel is between an SGML (Standard Generalized Markup Language) document. It has a gateway to get to other services via a gateway metro (archie, WAIS, Gopher, WWW, FTP, Internet News, etc.) Documents are spread all over the net, via links. If there are slow links, there are slow responses. Cooper [Page 39] Internet Monthly Report December 1993 Robert announced the formation of the European Consortium of WWW. He is forming it, as he sees a need to develop a commercial quality software group of existing professionals in Europe. Why? Concentrate efforts and resources. How does ATM influence it? Needs better reliability. Robert stated that WWW is a welcome and necessary edition to schools and libraries. There was a discussion between George Brett and Robert Cailliau in regards to commercial versus non-profit environments. George mentioned that CNIDR (Clearinghouse for Networked Information Discovery and Retrieval) was founded to prevent orphan software, and that the software is freely available to the public, and from a non-profit environment, not just specifically coming from the commercial sector. Cooper [Page 40] Internet Monthly Report December 1993 1.4.2 David Sitman - EARN "EARN Documents" EARN document availability is by electronic mail via: listserv@EARNCC.BITNET. get DOC file List get EARN brochure get NETTOOLS.TXT EARN documentation started two years ago, and is specifically concerned with NJE (Network Job Entry) users. The EARN User Support group is not protocol bound, as not everyone has FTP, Telnet, or NJE. However, everyone does have email. EARN's "Guide to Network Resource Tools" is in its second edition, and was made available at this conference. 1.4.3 Joyce K. Reynolds - Information Sciences Institute "Panel Discussion on User Support Issues" Joyce Reynolds (US) chaired the user support forum session, which included the following panelists: Bert Stals (NL), Jill Foster (UK), David Sitman (IL), and Robert Cailliau (CH/F) The session encouraged audience participation, besides participation from the panelists. Issues included: - What has become of last year's conclusions (i.e., closer cooperation with the networking community and librarians)? - Flea market versus department store - Cost of information versus free information (and the relation with quality) - Have we lost control of the network? During the allotted time, there was a spirited round robin discussion of the above issues, with each panelist making a brief opening statement, then opening up the discussion to the audience. Cooper [Page 41] Internet Monthly Report December 1993 2. The RARE ISUS Working Group Meetings The RARE Information Services and User Support (ISUS) Working Group, chaired by Jill Foster, met in tandem with EARN's Network Services Conference (NSC). The first meeting was held all day on the 11 October. The second meeting was held the afternoon of 15 October. Introductions were made around the meeting room and the agenda items were discussed. ISUS identified points for collaboration: Start small - identify 2-3 concrete items Get volunteers who will work as a two way link Network "mentors" - are overloaded, but are experts in their field Take part within European countries Enlighten people within local countries about ISUS' work Raise national projects to a European level Look inwards and outwards Consider an ISUS group in your own country. 2.1 Documentation Task Force Bert gave an overview of the progress of the Documentation Task Force. Defining goals and writing the short introductory pamphlets on WAIS, WWW, Gopher, email, etc., had been successful. However, the short guides had not really taken off and had been overtaken by events. Judy Koren (IL) mentioned that there is a real need for documentation in other languages than the "default" language of English. Will this ISUS Task Force assist in this need? Jill commented that the aim of this Task Force is to provide short leaflets and that other countries can feel free to translate the leaflets for their own user groups, with the stipulation that they put the results out on the network. Bert added that it is not the intention to set up a new line of documentation, but to improve existing material. 2.2 Brief report on Document Delivery by Maria Heijne (NL) A Document Delivery Task Force was supposed to be formed back at the NSC meetings in Pisa, Italy. Maria submitted a report, but with no response back except from the UK. Last June, Maria submitted another report, and did receive some response, but not from any of the ISUS group. She is now asking again for ideas. Cooper [Page 42] Internet Monthly Report December 1993 2.3 ISUS Newsletter Anders Gillner was producing one, but did a lot of the work by himself. He needs assistance. Maria volunteered to help by sending items of interest to the ISUS list. 2.4 INET/JENC94 Meeting in Prague Jill announced that she was asked to Chair the "User Support and Applications" track of the INET/JENC94 meetings in Prague. She has accepted and asked Joyce Reynolds to co-chair with her in this endeavor. Joyce has accepted the invitation to co-chair. Jill and Joyce requested ideas on papers from the ISUS WG. 2.5 Coordination of Information Services in Europe Anders Gillner and Tom Verschuren (NL) led a discussion on the Gopher issues. There is a European Gopher structure set up. Stockholm is the starting place with national entry points. Additional discussion included: Status reports Coordination National Veronicas National Entry Points Quality of Service Maintaining information Next Generation of Gopher - more to do? The IETF's "Integrated Information Architecture" concept was brought up by Erik Huizer (NL) and Joyce Reynolds. More discussion on this topic will be at the Houston IETF. Anders queried if there were any CNI (Coalition for Networked Information) type initiatives in Europe. No one currently knew of any. Cooper [Page 43] Internet Monthly Report December 1993 2.6 Reports on EARN, IETF and RARE activities Current reports were presented by representatives of EARN, RARE, and the IETF in the area of user support. 2.6.1 David Sitman (EARN) David stated that EARN covers a larger geographical area than RARE which includes Europe, the Middle East and Africa. EARNINFO meetings are usually attended by those also attending the EARN technical group meetings, and are not specifically made up of user support people. The real work is performed by a paid staff. EARNINFO focuses on general end user issues and makes no distinction between the NJE and the Internet users. As the use of NJE is still growing in new countries (NJE still proves to be a good, quick startup for international networking) there is still a need for documentation. As to the issue of EARN cooperation with RARE/ISUS initiatives, David stated that a merger between the two is not impossible and could be desirable, but on the other hand something may also be said of healthy competition. 2.6.2 Jill Foster (RARE) RARE ISUS Working Group covers a broad range of people and activities where most of the work is done in task forces. It is a volunteer effort and is open to everyone interested in participating. Current activities and task forces include: - RARE Technical Report 1 (RTR1): an up to date status report of user support and information services in Europe - UNITE: User Network Interface To Everything - MultiMedia Information Services - Networked Information Retrieval (Tools and Groups) report - Co-ordination of Networked Information Retrieval Services in Europe - User Documentation - Document Delivery - Network Training Materials - Support for Special Interest Groups - User Requirements of Automatic Mail Based Servers Cooper [Page 44] Internet Monthly Report December 1993 2.6.3 Joyce Reynolds (IETF) The IETF was originally a technically oriented group, but as of March 1990, User Services efforts were formed as its own separate area. The IETF User Services Area is made up of a User Services Area Council, the User Services Working Group (USWG), which is the umbrella group that spawns new working groups in this area, and various other working groups. The aim of the User Services Area is to enhance the cooperation of user support in internetworking. The User Services Area provides information for the people doing the first level user support. It is seen as a second level provider of user support. Joyce mentioned the following list of working groups and projects that are currently underway as part of the IETF User Services Area: - IAFA (Internet Anonymous FTP Archives) - IDS (Integrated Directory Services) - IIIR (Integration of Internet Information Resources) - ISN (Internet School Networking) - NIR (Network Information Retrieval) - NISI (Network Information Services Infrastructure) - TRAINMAT (Network Training Materials) - URI (Uniform Resource Identifiers) - USERDOC (User Documentation) - USWG (User Services Working Group) - WNILS (WHOIS and Network Information Lookup Service) Many of these projects and activities have produced documentation that have been published as "FYI RFCs" (For Your Information). FYIs are a subseries of the RFC series of notes. FYIs are introductory and overview documents for network users. Their purpose is to make available general information, rather than the protocol specifications or standards that is typical of other RFCs. Joyce commented that there are currently 21 FYIs, including FYI 19, "FYI on Introducing the Internet-- A Short Bibliography of Introductory Internetworking Readings", (Also RFC 1463), May 1993. The IETF User Services Area and the RARE ISUS WG continue to work in parallel and in a complementary fashion, with coordination between Jill and Joyce. 2.7 Network Training Materials Task Force Jill introduced the Network Training Materials Task Force which is a joint Working Group with the IETF and liaises with Australian groups. This work is based heavily on the UK's NISP/ITTI Network Training Materials Project based in Newcastle (see section 1.1.2 Cooper [Page 45] Internet Monthly Report December 1993 for further information). Margaret Issacs (UK), the Project Officer, gave an overview of this work. The aims of the RARE/IETF Network Training Materials Task Force/Working Group and the ITTI Project activities are to make a catalogue of already available training materials and make this available to the network community. The catalogue will soon be available as an Internet- Draft. The Newcastle group is also developing the following network training materials: Item 1: "The World From Your Desk Top" This is already available with: - Presentations - Demos - Handouts - Workshop material Item 2: "Slicing Through the Maze of Networked Information Item 3: "Electronic Mail" Margaret made a call for volunteers to update the collection that has already been put together for the catalogue and to provide feedback on the Training Pack. 2.8 Support Discussion Subject Groups Task Force - Jill Foster 2.8.1 United Kingdom David Hartland (UK) reported that NISP target groups have been set up (see section 1.1.1 for further information). 2.8.2 The Netherlands Bert gave a status report on support activities for SIGs (Special Interest Groups). SURFnet has a low profile attitude, and they wait for groups to come to them. If SURFnet receives a help request from a potential SIG, they can assist in making project plans. Two projects have already been completed and two are still running. Cooper [Page 46] Internet Monthly Report December 1993 2.8.3 Germany Monika Roesler (DE) reported that in some cases, group support from DFN is in the form of hardware and software. They have one person funded for two years for training and motivating members, and to hold meetings. They've discovered that user groups would die out once the project leader departed. 2.8.4 United Kingdom Nicky Ferguson (UK) is the Networked Information Officer for the ESRC (Economic and Social Sciences Research Council). He encourages the use of networked information in the social science community. He works in collaboration with David Hartland of the NISP. He has produced a card referring to services over JANET that are of relevance to social scientists. This has been distributed very widely. Nicky also runs hands-on sessions so computer naive users can get accustomed to the computers, provides interaction with faculty members, and attention to the resources. There has also been an establishment of a social sciences Gopher. A National Information on Software and Services (NISS) group has been funded by the "Funding Body for Social Sciences", with Jill's assistance. 2.9 The Euromath Project - Flemming Topsoe (DK) This project was started in Warsaw and is ten years old. The aim is to create a homogeneous workstation environment for editing mathematical documents and for email. This includes the creation of a homogenus workstation and DTDs (Document Type Definitions) with the main emphasis on the editing side. On-going work includes a hypertext help system and an electronic mailer. It runs full SGML and the development portion is available. Euromath Version 1 will be released January 1994, which will include Gopher, WAIS and WWW. Ongoing work includes: hypertext help system electronic mailer personal file system (for accessing and creating databases) Cooper [Page 47] Internet Monthly Report December 1993 2.10 U.N.I.T.E. - George Munroe (UK) George Munroe led the UNITE (User Network Interface To Everything) discussion. UNITE started as a small closed group, but became an ISUS Task Force one year ago at the NSC in Pisa. It is an idea of a total service in the sense that the user would not have to learn many different interfaces or to know which tool to use to find the information he/she is looking for on the network. The scope and goals included: What an ideal interface should be? (Started last November) What systems are already out there? Benchmark tests for evaluating systems Evaluate these solutions Only 8-9 catalogue of review Dissemination of reports Question from George, "Should we continue? If so, how?" UNITE files Evaluation reports (in the UNITE archive) Evaluation of UNITE - new things or stay as they are? Protocols essential for networking people - that's it Put it out to a "real" user - any volunteers? Any topics to introduce on the list Not much input on information management Should UNITE be thinking about it? - Probably YES. The attendees agreed that the UNITE work should go on. The work and discussions on the list are highly appreciated and George was thanked for his efforts.

A gleam of pale sand, a whisper of deep flowing waters, and a farther glimmer of more sands beyond them challenged our advance. We had come to a "grapevine ferry." The scow was on the other side, the water too shoal for the horses to swim, and the bottom, most likely, quicksand. Out of the blackness of the opposite shore came a soft, high-pitched, quavering, long-drawn, smothered moan of woe, the call of that snivelling little sinner the screech-owl. Ferry murmured to me to answer it and I sent the same faint horror-stricken tremolo back. Again it came to us, from not farther than one might toss his cap, and I followed Ferry down to the water's edge. The grapevine guy swayed at our side, we heard the scow slide from the sands, and in a few moments, moved by two videttes, it touched our shore. Soon we were across, the two videttes riding with us, and beyond a sharp rise, in an old opening made by the swoop of a hurricane, we entered the silent unlighted bivouac of Ferry's scouts. Ferry got down and sat on the earth talking with Quinn, while the sergeants quietly roused the sleepers to horse. Plotinus is driven by this perplexity to reconsider the whole theory of Matter.477 He takes Aristotle¡¯s doctrine as the groundwork of his investigation. According to this, all existence is divided into Matter and Form. What we know of things¡ªin other words, the sum of their differential characteristics¡ªis their Form. Take away this, and the unknowable residuum is their Matter. Again, Matter is the vague indeterminate something out of which particular Forms are developed. The two are related as Possibility to Actuality, as the more generic to the more specific substance through every grade of classification and composition. Thus there are two Matters, the one sensible and the other intelligible. The former constitutes the common substratum of bodies, the other the common element of ideas.478 The general distinction between Matter and Form was originally suggested to Aristotle by Plato¡¯s remarks on the same subject; but he differs325 from his master in two important particulars. Plato, in his Timaeus, seems to identify Matter with space.479 So far, it is a much more positive conception than the ?λη of the Metaphysics. On the other hand, he constantly opposes it to reality as something non-existent; and he at least implies that it is opposed to absolute good as a principle of absolute evil.480 Thus while the Aristotelian world is formed by the development of Power into Actuality, the Platonic world is composed by the union of Being and not-Being, of the Same and the Different, of the One and the Many, of the Limit and the Unlimited, of Good and Evil, in varying proportions with each other. The Lawton woman had heard of an officer's family at Grant, which was in need of a cook, and had gone there. [See larger version] On the 8th of July an extraordinary Privy Council was summoned. All the members, of whatever party, were desired to attend, and many were the speculations as to the object of their meeting. The general notion was that it involved the continuing or the ending of the war. It turned out to be for the announcement of the king's intended marriage. The lady selected was Charlotte, the second sister of the Duke of Mecklenburg-Strelitz. Apart from the narrowness of her education, the young princess had a considerable amount of amiability, good sense, and domestic taste. These she shared with her intended husband, and whilst they made the royal couple always retiring, at the same time they caused them to give, during their lives, a moral air to their court. On the 8th of September Charlotte arrived at St. James's, and that afternoon the marriage took place, the ceremony being performed by the Archbishop of Canterbury. On the 22nd the coronation took place with the greatest splendour. Mother and girls were inconsolable, for each had something that they were sure "Si would like," and would "do him good," but they knew Josiah Klegg, Sr., well enough to understand what was the condition when he had once made up his mind. CHAPTER V. THE YOUNG RECRUITS Si proceeded to deftly construct a litter out of the two guns, with some sticks that he cut with a knife, and bound with pawpaw strips. His voice had sunk very low, almost to sweetness. A soft flurry of pink went over her face, and her eyelids drooped. Then suddenly she braced herself, pulled herself taut, grew combative again, though her voice shook. HoME²Ô¾®Ïè̫ʲôÐÇ×ù ENTER NUMBET 0016kxchain.com.cn
