The 28th meeting of the IETF, co-hosted by SESQUINET and Rice University, was held in Houston, Texas from November 1-5, 1993. The first meeting of the IETF in 1994 will be held in Seattle, Washington from March 29 through April 1, 1994. This meeting is being hosted by NorthWestNet. Following the March 1994 meeting, it looks like the IETF will be in Toronto in July, and in the San Francisco Bay Area in the fall. Once the final arrangements have been made, notifications will be sent to the IETF Announcement list. Remember that information on future IETF meetings can be always be found in the file 0mtg-sites.txt which is located on the IETF shadow directories. 2. The IESG has determined how documents from the IPng candidates will be treated when they are submitted to the IESG for publication as RFCs. a. All IPng-related documents will be submitted for publication as RFCs in normal fashion; that is, as soon as the working group and the area directorate recommends that the IESG review them for publication. All IPng-related RFCs will be published with Experimental status. All IPng-related RFCs will remain in Experimental status until a single IPng is selected. b. At some point, one IPng shall be selected, and it will be moved onto the standards track as defined in RFC1310 (or its successor). An Applicability Statement will be prepared to assign a status of "Recommended" as the Common IPng for Internet interoperability. c. Once a "Common IPng" protocol has been selected, the other (former) IPng candidates will be treated in normal fashion. That is, they may eventually be moved to Historic status, or, if recommended by the working group and area directorate, they may be moved onto the standards track. However, because there can be only one level three protocol with a status of "Recommended as the Common IPng for Internet interoperability", an Applicability Statement must be prepared that clearly distinguishes between the subject protocol and the "Recommended Common IPng". Cooper [Page 3] Internet Monthly Report October 1993 3. The IESG approved or recommended the following nine Protocol Actions during the month of October, 1993: o MOSPF: Analysis and Experience as an Informational document o OSPF Version 2 as a Draft Standard o Multicast Extensions to OSPF as a Proposed Standard o The Point-to-Point Protocol (PPP) as a Draft Standard o PPP in HDLC Framing as a Draft Standard o Common DNS Data File Configuration Error as an Informational document o Common DNS Implementation Errors and Suggested Fixes. as an Informational document o FTP Operation Over Big Address Records (FOOBAR) as an Experimental Protocol o Requirements for an Internet Standard Point-to-Point Protocol as an Informational document 4. The IESG issued four Last Calls to the IETF during the month of October, 1993: o Classical IP and ARP over ATM being considered as a Proposed Standard o OSPF Version 2 being considered as a Draft Standard o Multicast Extensions to OSPF being considered as a Proposed Standard o Telnet Environment Option being considered as a Proposed Standard 5. Two Working Groups were created during this period: Internet Stream Protocol V2 (st2) Routing over Large Clouds (rolc) Cooper [Page 4] Internet Monthly Report October 1993 Additionally, two Working Groups were concluded: Internet Message Extensions (822ext) Network News Transport Protocol (nntp) 6.

This upgrade will include several T3 router performance enhancements. New rcp_routed routing software was deployed in October. New GateD routing software is expected to begin deployment in November. A new CNSS node was installed in Albuquerque, New Mexico to support T3 services. October Backbone Traffic and Routing Statistics =============================================== The total inbound packet count for the network (measured using SNMP interface counters) was 43,689,832,748 on T3 ENSS interfaces, up 21.9% from September. The total packet count into the network including all ENSS serial interfaces was 51,080,653,716 up 22.4% from September. Major T3 Network Upgrade Planned ================================ Starting on November 6th, a major upgrade to the T3 ANSnet/NSFnet Service will be deployed. We are calling this the "Phase-5 upgrade" since it represents the 5th major change to network infrastructure that we have made since 1991. The infrastructure upgrade to the T3 network will begin deployment on Friday 11/6 in Seattle and Denver, and will continue at each T3 ENSS site and CNSS POP location during pre-scheduled weekend maintenance windows through 12/18. The major changes included in this upgrade are: 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 will also be upgraded to double the packet switching rates per interface. o The architecture for interconnection among CNSS routers at each MCI POP location will be upgraded from point-to-point links to a common FDDI ring. o The T3 DSUs on each DS3 interface will replaced with a T3 bandwidth manager (T3Plus BMX45) to accommodate T3 CNSS-CNSS Cooper [Page 10] Internet Monthly Report October 1993 circuits and a Larscom Access-T45 DSU on each end of a T3 ENSS-CNSS circuit. o New system software and microcode will be installed (already in progress) prior to the hardware deployment to support the increased adapter performance. Routing software has already been deployed to support the new CNSS FDDI ring architecture. Deployment Schedule Summary --------------------------- The upgrade will be deployed in six steps, commencing on Friday evening November 6th, and ending on the weekend of December 18th. the upgrade will be suspended for the week of Thanksgiving. Some deployment details and the deployment schedule follow below: - The T3Plus BMX45N bandwidth managers will be installed on the first POP visit. CNSS sites will have multiple visits to upgrade the backbone links. - T3 ENSS sites are visited once and are upgraded concurrent with the adjacent DS3 linked CNSS. - The ANS NOC will create a planned maintenance trouble ticket with the ENSS site well in advance of maintenance and will confirm with the site a few days in advance. - All parts will be delivered to the ENSS site on the Thursday preceding the scheduled Friday evening upgrade.

The "Both IBGP and EBGP Aggregation" version or rcp_routed was deployed early in October. The "Both IBGP and EBGP Aggregation" version further improves performance, and also allows the CNSS nodes to be interconnected using a FDDI ring rather than point-to-point interfaces within the carrier POPs. A new version of rcp_routed will be installed in early November. This version more efficiently processes policy information (see Cooper [Page 12] Internet Monthly Report October 1993 below). 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. Steady improvement that has been observed since June. 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% The figures above exclude logs collected at the ENSS200 router which was used to provide temporary T3 connectivity for a trade show. While there was no stability problems with this node, it was never xntp time synchronized and its skewed timestamps tended to make any minor instabilities during that week appear longer than they were. Stability figures for ENSS200 are included by virtue of the logging information collected on it's IBGP neighbors. Severe route flap outside of ANSnet affected rcp_routed in October. A rogue application was discovered walking through the IP address space, starting with the class A numbers and transmitting UDP echo packets to these destinations. This affected routers outside ANSnet, which had difficulty processing the ICMP unreachable messages to be sent. The volume of route flaps affected ENSS nodes with a very large number of configured peer network announcements (5000-8000 networks). The efficiency of the run time search through configured policy information in rcp_routed was improved to prevent this in the future. ENSS136, ENSS144, and ENSS145 were affected. The source network responsible for the rogue application was isolated and the UDP echo packets have since ceased. ENSS160 (ANS Elmsford) experienced numerous crashes due a hardware failure which was subsequently fixed. Cooper [Page 13] Internet Monthly Report October 1993 ENSS138 saw instability associated with the cutover of a new T3 circuit. Instabilities were recorded as part of the cutover. Other than the specific problems cited above, power problems on the customer premise was responsible for the greatest amount of measured instability. A new router system software build was installed at a few T3 ENSS sites, causing limited instability of on the order of 10 minutes. Two new versions of rcp_routed were installed during October. Route convergence has improved, limiting the disruption of a backbone wide routing daemon install to about 5 minutes. The number of nodes experiencing more than 30 minutes accumulated has been significantly reduced. The vast majority of nodes had less than 15 minutes of accumulated instability over the course of the month. The breakdown by sites is as follows (these figures include instabilities recorded during configuration runs): 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 GateD Deployment Update ======================= During October we continued testing the initial GateD release for the T3 network that supports BGP4 and interoperability with rcp_routed. A recent change resulting from testing involves improved protocol processing during large route downloads from the AIX kernel to the packet forwarding adapters. We expect deployment of GateD to begin in November with support for external BGP version 4 peers available soon thereafter. Cooper [Page 14] Internet Monthly Report October 1993 Albuquerque POP Installation ============================ On November 5th a new CNSS node will be added to the T3 ANSnet in Albuquerque, New Mexico. This CNSS will initially support two new T3 ENSS sites in Albuquerque (Sandia National Laboratories and Phillips Laboratories). Within the next few months, additional CNSS equipment will be added to support the attachment of other networks in the Albuquerque region. Notable Outages in October '93 ============================== UNAM (Mexico) suffered an extended circuit outages on 10/01 and 10/21. E173 (ITESM) suffered an extended outage on 10/3 due to power problems. EBS2 (Cern) suffered extended circuit outages on 10/5, 10/6, and 10/10. E173 (ITESM) suffered an extended circuit outage on 10/11. E141 (Boulder) and E142 (Salt Lake) lost T3 connectivity on 10/12 due to hardware problems due to hardware problems on a core router. Jordan Becker BOLT BERANEK AND NEWMAN INC. ---------------------------- Real-Time Multicast (Communications) ------------------------------------ Work in September concentrated on testing and demonstrating the various network capabilities developed in the project. With the help of other DARTnet researchers, we performed several tests on the DARTnet testbed of multi-level flows, RCOs (Resource Coordination Objects), and shared streams. These tests used a modified version of the "nv" video-conferencing program that supports multi-level video data flows (described in last month's report), and the standard version of the VAT audio-conferencing tool, which was used for a shared-stream-based audio conference. The shared-stream experiment uses RCOs to propagate reservation information for each VAT audio source, which share common bandwidth where the flows overlap in the network. The Fair Share resource- Cooper [Page 15] Internet Monthly Report October 1993 enforcement mechanism was used to enforce the bandwidth reservations for the multicast flows. Inter Domain Policy Routing --------------------------- During the months of September and October, we made considerable progress on our implementation of multicast and multipath routing for IDPR. This involved changes to the procedures for generating routes, setting up paths, and distributing routing information. Although only minor changes to the IDPR protocols are required to support both multicast and multipath routing, the software for route generation and path setup required extensive redesign to support these features. We expect to start testing in December. Karen Seo CONCERT ------- CONCERT has received two NSF Connections Grants allowing for the connection of 16 Universities / Colleges/ Community Colleges in the State of North Carolina. The communications research group's resource management experiment has been slowed down a bit due to switching to Solaris 2.2. However, the real time (RT) scheduling class in Solaris 2.2 seems to be useful for a number of networking and multimedia experiments. For example, we expect to use this support in implementing a leaky bucket mechanism and in implementing an audio echo cancellation algorithm. Work is underway to port the University of Virginia, Charlottesville implementation of XTP(version 3.6) for the IBM RISC 6000 platforms running AIX to the Cray-YMP-EL running UNICOS. This implementation of XTP is more efficient compared to the KRM version (KRM 1.6 and 1.7) that was ported to the Cray earlier this year. An updated version of the packet video catalog listing packet audio and video packages (based on the previous work of to Chris Adie) will be placed on the ftp site ftp.concert.net early this week. This is a live document and will be updated periodically as new packages are announced and existing ones evolve. by Tom Sandoski Cooper [Page 16] Internet Monthly Report October 1993 INTERNIC --------- INFORMATION SERVICES Contact Information: Reference Desk Information Toll-free hotline +1 800 444-4345 email info@internic.net Fax +1 619 455-4640 InterNIC Suggestions or Complaints Suggestions suggestions@internic.net Complaints complaints@internic.net NSF Network News newsletter subscriptions newsletter-request@internic.net newsletter comments newsletter-comments@internic.net Listserv lists net-happenings listserv@internic.net net-resources listserv@is.internic.net nics listserv@is.internic.net InfoSource Host Name is.internic.net Host Address 192.153.156.15 Postal address InterNIC Information Services General Atomics P.O.

Complete instructions for use of the mail server are available by sending mail to mailserv@ds.internic.net and putting the word "help" (without the quotes) in the BODY of the message. We have tried to make as many services as possible available through the mail server, including access to all files available via FTP and the ability to search our Directory of Directories. A few of our services (e.g. Netfind) require interaction between the user and the service, so they are not available through the mail server. The basic services available include: - access to all files on our server that can be reached by FTP - access to X.500 and WHOIS directory searches - directory of directories searches by topic Cooper [Page 20] Internet Monthly Report October 1993 - keyword searches of our document collection We also support access to archie by mail. For compatability with the rest of the archie world, archie is accessed by sending mail to "archie" rather than sending mail to "mailserv". To help spread the load a bit, there are a few restrictions on use of the mail server: - each message is limited to 15 queries and file transfer requests - the information returned by file transfer is limited to 500K bytes - CPU time for message processing is limited to 15 seconds One frequent cause of errors with the mail server is that the command is put on the "Subject:" line rather than in the body of the message. Since our server accepts multiple commands per message, we accept commands from the body of the message rather than the "Subject:" line. A reminder - if you would like to help the Internet community find a resource that you offer, send mail to admin@ds.internic.net and we will send information about listing your resource in the Directory of Directories. by Rick Huber REGISTRATION SERVICES I. Significant Events During the month of October, the InterNIC changed the menu selections on the 1-800 number. Customers calling the numbers are now being referred to #1 Information Services, #2 Directory and Database Services, and #3 Registration Services. This change reduced confusion for callers and for InterNIC staff members. The Internet continues to grow every month. According to our statistics there are over 12,252 domains in the InterNIC database and we also registered a record 729 inverse addresses as well. The Internet is becoming more popular than it's ever been and the general public is reaping the benefits. Cooper [Page 21] Internet Monthly Report October 1993 II.

One cable is 100' long and the other is 120' long. Each have been tested at about 300Mb/s and have been running for several weeks without significant problems. 2) We have been actively examining various design alternatives for this VL-Bus ATOMIC interface card. Recently we have decided to replace the Memoryless Mosaic chips in our design with the forthcoming Lanai chip that should be available in January. Cooper [Page 22] Internet Monthly Report October 1993 Pinouts will be available in December, so our complete board layout will begin at that time. The Lanai chip is optimized for network interfacing and will include some features for real-time scheduling. 3) We have moved the Address Consultant code into the kernel This makes the code more portable to operating systems other than SUN OS and allows sites without a source license to install the ATOMIC device driver into their systems. The code has been made available to selected sites with ATOMIC hardware. 4) We recently installed a 64-processor Mosaic-C board as the main switch in our LAN. It provides 16 bidirectional ports for connecting hosts or other switches. We have verified its correct operation and are working on integrating it into the network.

Mmcc is a session orchestration tool that allows a user to explicitly invite others to participate in a conference, and alerts them to accept or decline. Mmcc is an X-based tool that provides both point-to-point and multipoint teleconferences. It automatically spawns underlying audio, video and groupware programs among members of a session, then tears them down at session completion. Currently, mmcc brings up vat by default, and offers the option to start nv and wb, but in the future we'd like to support other MBone tools as well. Mmcc will distribute a session key for confidential sessions. In this preliminary version, the key is sent in the clear, so it is not secure, but eventually we expect to use other techniques for secure key distribution. Cooper [Page 27] Internet Monthly Report October 1993 Mmcc aims to supplement the large open-style sessions supported by the existing version of sd. It complements the hailing-channel approach of public sessions with a more private session style for smaller conferences. Thus, session advertisement is internal to the group of participating conferees. The mmcc release software is available via anonymous FTP from "ftp.isi.edu:confctrl/mmcc.tar.Z". The Realtime Transport Protocol (RTP) specification from the IETF Audio/Video Transport working group has been augmented to provide for application-specific option number assignment and to clarify and explain a number of points. With these edits completed, the document has been submitted to the IESG for the "Last Call" before publication as an RFC.

Walt Prue (Prue@ISI.EDU) MERIT/MICHNET ------------- At the close of October, Merit has grown to ten member institutions and 60 affiliates. Northern Michigan University in Marquette is the newest Merit Member. NMU will initially have two 56Kbps attachments, one linking the university to the MichNet node at Michigan Technological University and the other to the backbone node in Grand Rapids. NMU will host the Marquette MichNet dial-in, Cooper [Page 29] Internet Monthly Report October 1993 as well as Michigan State University facilities. The Rapid Response Manufacturing Center in Redford, Michigan will be connected at 56Kbps to the MichNet node at Wayne State University. The manufacturing technology and research organization, sponsored by the National Center for Manufacturing Sciences, will fund its MichNet connection through a grant from the National Institute for Science and Technology (NIST). Jackson Community College recently upgraded to a 56Kbps link with the assistance of an NSF Connections grant. JCC also participated with Merit in upgrading the Jackson area MichNet dial-in service, bringing additional phone lines into the Jackson hunt group. The new modems will also be compatible with Merit's planned Network Access Servers (NAS) scheduled for deployment throughout the MichNet backbone in 1994. The Livingston PortMaster at the University of Michigan MichNet site is now in production. The dial-in access offered through the UM/MichNet NAS is currently limited to PPP (Point-to-Point Protocol) access only and requires authentication. Access will be broadened to include dumb-terminal emulation in the future. NAS configuration is specified for flexibility in modem speeds, error correction and data compression. Sandra Waite represented Merit/MichNet interests at "Building Consensus/Building Models for K12 Networking Assistance," a project funded by the National Science Foundation and carried out by FARNET and CoSN (the Consortium for School Networking). This new initiative will work to bring together leaders in K12 education, networking and public policy to develop models for successful technical assistance to schools implementing school-based networks. Dana Sitzler, Merit K-12 Outreach Coordinator, participated in the National Information Infrastructure Education Forum in Washington, D.C. Sitzler also presented information on "how to get connected" to the Internet and Merit's "Cruise of the Internet" at the Michigan Association for Educational Data Systems (MAEDS) conference in Bellaire, Michigan and the October Tech Expo held in Petoskey, Michigan. Sitzler and Ellen Hoffman, Merit's Development Director, attended the Great Lakes Council of Governors Summit on Information and Technology, held in Indianapolis, IN. Laura Kelleher, Merit's Network Applications Coordinator, presented Merit's "Cruise of the Internet" at October meetings of MACUL and the Michigan Library Association. Pat Smith, Merit Customer Service Coordinator, provided information resources at the MLA gathering. A special edition of Merit's "Cruise of the Internet" and a hands-on demonstration of Internet tools and resources for 275 employees Cooper [Page 30] Internet Monthly Report October 1993 from various State of Michigan departments was designed and presented by Smith, Steve Burdick, Betty Van Dam and Ellen Hoffman. The State of Michigan has adopted TCP/IP as the networking standard for the state's departmental initiatives. Jo Ann Ward (jaw@merit.edu) Merit Network, Inc. Information Services MERIT/NSFNET INTERNET ENGINEERING --------------------------------- This report contains a summary of recent activities of Merit's Internet Engineering Group. These include development of capabilities in the Policy Routing Database system to represent, generate NSFNET/ANS backbone configuration files, and test new software, for deployment of the CIDR and BGP-4 routing architecture. Additionally, Merit staff have made progress on implementation of a "CIDR Aggregate Registry", described in RFC 1482, for registration of aggregated routing information between providers. In early October, Merit hosted a meeting of the Regional-Techs group, which discussed a number of topics related to coordination among providers for CIDR deployment and registration of routing information. The Shared Whois Project (SWIP) is an ongoing joint project between InterNIC, RIPE NCC and Merit. Policy Routing Database Changes and CIDR Deployment In preparation for deployment of the GateD routing daemon on the ANS backbone, supporting the BGP-4 protocol for CIDR, changes were completed in the Merit/NSFNET PRDB in order to support inbound acceptance and outbound announcement of route aggregates. The PRDB can now generate GateD configuration files for the ANSNET backbone. These files can include configuration for the new BGP-4 features. Merit engineers are cooperating with the ANS backbone engineering staff in testing GateD operation on the T3 research network, and in the initial deployment of the new version of GateD on the Washington DC to Geneva, Switzerland circuit. The initial production deployment of the PRDB changes for CIDR will include a change in the notation of network numbers to the classless format ("x.x.x/len"). This change will be visible to all external users of whois or the PRDB reports. The whois server commands will start using the new notation, and ans_core.now, country.now, and net-comp.now will be replaced with their new versions (currently produced as ans_core.cidr, country.cidr, and net-comp.cidr). Prefix lengths of 8, 16, or 24 will be put into Cooper [Page 31] Internet Monthly Report October 1993 the PRDB for all existing nets with classes A, B and C respectively. The Network Announcement Change Request (NACR) templates, both e- mail and interactive client interfaces, will be changed to accept aggregated announcements. Once GateD is deployed, BGP-4 will be supported initially without announcing or accepting aggregated routes, however. After BGP-4 appears to be stable, controlled experiments with aggregation will be done in cooperation with regional and midlevel networks. Still to be implemented in the database is the "proxy aggregation" as described in RFC 1482. In this case the backbone can be configured to aggregate on behalf of the regional network in response to the announcement of one or a set of network numbers comprising the total aggregate. This feature will be supported by the time NACR support for aggregation is made available. CIDR Aggregate Registry Changes to the Aggregate Registry function described in RFC 1482 were made at the October Regional-Techs meeting. The original proposed functionality was split into a Aggregate Registry (one entry per aggregate, with source AS) and a possible separate Routed Net registry giving AS topology with aggregate announcements. Initially these registries will list only network prefixes which are not class A/B/C nets, but the longer term goal is to allow all nets regardless of class to be returned by the same server. The Aggregate Registry project will be implemented first as it is a relatively straightforward project, with the Routed Net Registry project being implemented next. It is expected that these registries will be of assistance in the global BGP-4 tunnel testbed led by Andrew Partan and Peter Lothberg. Regional-Techs Meeting A meeting of the Regional-Techs group was held in Ann Arbor on October 4-5. The focus of the meeting was to discuss CIDR Deployment, routing registration, and NSFNET transition issues with respect to coordination among network providers. The group decided that it will be important to broaden its scope to include any interested network providers rather than restrict the discussion to NSFNET-attached regionals and midlevels. It was decided that for the foreseeable future, Merit will continue to host the group, but meetings may be held at different locations with other network provider sponsors. A suggestion for a new name for the group was Cooper [Page 32] Internet Monthly Report October 1993 North American Network Operators Group, though a name was not finalized and is open to discussion. A summary of the meeting is available for anonymous ftp: merit.edu:pub/nsfnet/regional-techs/1093/rtechs.ps SWIP Project The Shared Whois Project is a joint project between Merit, RIPE NCC and InterNIC to synchronize data among the Internet numbering and routing registries, and implement various databases and implement automatic update procedures. It is a goal of the three organizations to synchronize data by April, 1994 and begin to use the update procedures at that time.

In addition to 5 keynote presentations and 21 track sessions, a 7.5 hour, three part series on libraries and computing centers was held to examine the evolving relationships between these two groups. The series examined areas of overlap and conflict--from mission statements to solving users problems--and through dialogue began exploring the foundations of cooperative production and distribution of integrated, electronic information services. Keynote presentations included an inspired and fresh view of what the Internet and K-12 can bring to each other (Fred Dust, The Bush School); an overview of the current NSFNET backbone and NREN (Richard Mandelbaum, NYSERNet); a look at national NII policy under development (Charles McClure, Syracuse University); an examination of cooperative ventures and commercial interests in the development of the NII (Jim Elias, US West); and an overview of the current state of, and future opportunities for, NorthWestNet (Eric Hood, NorthWestNet). All NorthWestNet governance and representative committees-- executive committee, board of directors, institutional representatives, technical services representatives, and user services representatives--convened in conjunction with the Annual Cooper [Page 35] Internet Monthly Report October 1993 Meeting. Two major new services for NorthWestNet members were unveiled in October. First, a NorthWestNet Gopher, that includes an online, searchable version of "The Internet Passport," was announced and made available to our member communities. Second, the Willow graphical information retrieval tool, designed by the University of Washington, is also now available to the NorthWestNet member community for use in accessing online, text-based bibliographic databases.

Mark Handley also presented two papers, on the MIE project and on a comparison of the various multicast schemes proposed by the members of the IDMR group. We had ISDN calls to a variety of places, and then used the MICE CMMC to mix them into an Internet multiway conference with audio, video and whiteboards. An effective demonstration tool has developed - the use of the game person a word, which they then attempt to draw in a wb, and the other particpants attempt to guess what the word was. Winner is frst correct guess, and chooses next word. While running this, we have been working on a tool for helping diagnose mbone problems based on background monitoring of the topology with a triggered traceroute -g on any suspect route, via the first hop mrouted, to the destination one.

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 0016www.gxxsgj.com.cn
