Brian Carpenter IAB Chair INTERNET ENGINEERING REPORTS ---------------------------- IETF Monthly Report for July, 1996 1. The IETF met in Montreal, Quebec, Canada from June 24-28, 1996. While we're still working on the numbers, this was the best attended meeting in the IETF's history with over 1200 registrants. Closing out the year, the IETF will be returning to San Jose, California from December 9-13, 1996. Following that, the IETF travels to Memphis, Tennessee where Federal Express will be the host. This meeting will be held April 7-11, 1997. We are currently working on returning to Europe in August, 1997. Once all the 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. This information can also be viewed from the IETF Home Page on the Web. The URL is: http://www.ietf.org 2.

Significant Events * HostReg and CReg templates are now being processed automatically; previously they had to be processed manually; now about 50% are being processed automatically. * The auto-registration software now sorts requests into six groups: (1) COM, (2) ORG, (3) NET, (4) GOV, (5) EDU and (6) TLD; this eliminates a manual step in the process and allows the ability to put an increased priority on GOV, EDU and TLD requests. * Plans to initiate a night shift are under development to assist in reducing the manual processing backlog. * Informal training was provided for Billing CSRs regarding how to register as a contact. IMR Editor [Page 11] Internet Monthly Report July 1996 * Selection and training of a second shift for processing support was completed; a full day training class was held on Saturday, September 10th; final staffing arrangements were completed for a night shift with a start date of September 30th. * A "SWAT Team" of existing staff was used to reduce the backlog. * Fax processing has become an overwhelming problem, requiring over four full-time equivalent employees. * Duane Stone and Carley Johnson represented the InterNIC DomReg Section at Network World Interop. * Testing of a share-ware Fax Server solution is going very well; it would make faxes available as e-mail; the fax viewer works very well on Sparc 5s and also supports sending faxes out; the MTS and Ack/Nak interfaces still need to be completed. * DomReg software enhancements have reduced the number of requests that need to be processed manually from about 1,000 to 700 (30% improvement). * A method for gathering performance measurements was finalized and documented.

In addition, InterNIC Directory and Database Services will become the new home of the netfind-servers mailing list. We have set up a Web page giving starting points for browsing information on the US government. While most of the entries are related to the Federal government, there is also a pointer to some information on state and local governments. 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. If you prefer, you can enter information about your resource in our WWW suggestion form. The form can be reached through our Directory of Directories Web page at: http://ds.internic.net:80/ds/dsdirofdirs.html by Rick Huber THE US DOMAIN REGISTRY ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The US Domain now has an online line registration form. Some of the processing of the requests to the third level domain name is now automated. In particular, most requests to register names in localities already delegated are automatically forwarded to the administrator for that locality. The US Domain administrator no longer makes direct registrations of hosts, and only makes delegations of third or fourth level domain names (such as localities). A new policy has been added to the criteria for delegating domain names under the US Domain: It is the intention that the delegation of third level (for example, locality) domain names be wide spread to many registries. It is undesirable for one person or organization to manage a large part of the third level names in any particular geographic or logical area. IMR Editor [Page 13] Internet Monthly Report July 1996 No individual or organization shall have more than 500 delegations total in the US Domain as a whole, or more than 50 delegation in any particuilar second level (for example, a state). To obtain a copy of the list of other delegated localities and subdomains not administered by the US Domain Registrar, get the file "us-domain-delegated.txt". URL: ftp://ftp.isi.edu/in-notes/us-domain-delegated.txt For further information about the US Domain, send a message to: US-DOMAIN@ISI.EDU, or see our WEB page: http://www.isi.edu/us-domain US DOMAIN ADMINISTRATIVE INFORMATION ------------------------------------ EMAIL/FAX 2899 PHONE 560 ---------------------------- Total Contacts 3459 DELEGATIONS 84 FORWARDED DELEGATIONS:1373 OTHER US DOMAIN MSGS: 2002 --------------------------- Total 3459 OTHER US DOMAIN MESSAGES INCLUDE: referrals to other subdomains or to/from the InterNic, phone calls, modifications, application requests, discussion and clarification of the requests, questions about names, resolving technical problems with zone files and name servers, and whois listings. In addition, and not listed below, another 226 localities have been delegated in Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Hawaii, Massachusetts, Maryland, Missouri, Montana, Michigan Mississippi, North Carolina, New Jersey, New York, Virginia, Vermont, Washington this month.

The Routing Arbiter project has updated its packet loss and latency measurement code to correct recently discovered measurement biases (see http://www.ra.net/statistics/rs.html). Previously, the packet loss and latency measurements were carried out using the standard Sun ping, which sent five ICMP echo request packets to each of the Route Servers' BGP peers every fifteen minutes. The response time (or lack of response) was logged in a file and later downloaded and processed. Periodically, aberrant measures were seen. For example, there was often packet loss/or and high latency when the machine ping'd its own interface. Packet loss data indicated higher loss and latency results than did other measures. IMR Editor [Page 16] Internet Monthly Report July 1996 Because Merit did not have the source code for the Sun ping, the engineering staff could not perform a detailed analysis to determine the cause of the problem. Staff did find, however, that the Cornell ping, to which they did have source code, did not display the same anomalies and provided much more credible measurements. As a result, a new data collection methodology has been implemented using the Cornell ping as a basis for the measurements. The data from all the Route Servers now shows improved Internet performance in comparison with the previous months' data. To provide data for further study, the primary Route Server at the Washington, D.C. NAP (MAE-East) is running the old and new pings in parallel. Comparing the two sets of results should shed additional light on the source of bias between the two measurement methodologies, and potentially permit an adjustment to deflate the previous measurements. Merit has been exploring options for resolving an important operational problem of the Route Servers, i.e., how to detect whether or not peers of the Route Servers have direct layer-2 reachability to each other. Though this issue was raised at one of the ATM NAPs, it would be problematic for any non-broadcast-media NAP, and is an important issue with respect to the reliability of both routing and the Route Servers. Currently, Merit and the Information Sciences Institute, its partner in the RA project, are evaluating the feasibility of obtaining layer-2 reachability information directly from Route Server peers via ICMP-level queries (traceroute with strict source routing). This is ultimately the source of the desired information and can be initiated by the Route Server without requiring SNMP access coordination and community string dissemination. Merit has implemented an incremental update client for the copies it maintains of the databases in the Internet Routing Registry. This client will poll primary IRR sites for updates on a regular basis (most likely every ten minutes). Currently, these sites only provide updated copies of the registries on a daily basis, so this technology will significantly improve the timeliness of the IRR data provided by RAWhoisd, the whois.ra.net whois server. The incremental update client has been in final test for the last weeks of July and will be deployed in early August. Initially, only the RIPE registry will provide incremental updates. However, we hope that all IRR registries will eventually adopt this technology. IMR Editor [Page 17] Internet Monthly Report July 1996 A new RA tool prototype, known as NetNow, combines a variety of real- time network statistics to provide an easy-to-use, graphical display of ongoing core Internet network conditions. See: http://www.ra.net/tools/ A map of the United States shows the four Network Access Points, and a menu bar lists the major U.S. Internet Service Providers. Names on the map and provider list are color-coded to indicate whether conditions are normal at the NAP or on the provider's backbone, or whether there are problems such as high packet loss or latency, excessive route flapping, unreachable networks, or scheduled maintenance outages. Information about the NAPs is collected by ICMP pings to Route Server peers and SNMP queries to the Route Servers. The ISP backbones are monitored by sending ICMP pings from each NAP across each provider backbone to every other NAP (creating a mesh). In the near future, pings will also be sent across the major ISP backbones to popular end sites. This process will test inter-provider connectivity and provide some statistics on the performance of provider tail circuits. A new software package called "Scion" is being developed by Merit's NetSCARF (Network Statistics Collection And Reporting Facility) project. Scion can be used by ISPs to collect network statistics and automatically display performance reports on the World Wide Web. Version 1.2 of the code is available from: http://www.merit.edu/~netscarf The Scion code, derived from the initial NSFNET project's statistics collection and reporting activities, is easy to install and runs automatically. Every fifteen minutes, Scion's optimized SNMP library queries ISP routers for the values of variables such as sysUpTim and ifLastChange. The library uses SNMP Version 1, and can be configured to use SNMPv2u, the User-based Security model for SNMPv2. Scion's SNMP API is unique, in that it allows the developer to specify a list of nodes, a community string (or userid/authentication password/privacy password in the case of SNMPv2u), and a list of management objects to retrieve. All queries are then transmitted back-to-back, without waiting for any replies. The data collection activity is thus very fast, and the results highly synchronized. Other publicly available SNMP libraries force applications to wait for a response (or timeout) for a given query before the next query can be issued to a different node. IMR Editor [Page 18] Internet Monthly Report July 1996 The raw SNMP statistics are pre-processed each evening, and the processed data delivered to CGI scripts, using what the developers believe to be the first public domain implementation of the OpStats (RFC 1856) client/server model. Finally, ISP performance reports based on the 'cooked' data are displayed on the Web via the CGI scripts. ISPs can use the Scion code to automatically produce HTML graphs showing system uptime, interface uptime, and total network traffic measured in packets. An advanced statistics Web page allows users to specify customized graphing parameters. The source and pre-compiled executables are available for the BSDi and SunOS platforms. Release 2, scheduled for October 1996, will include ports to Windows NT, AIX, and perhaps Solaris and LINUX. A technical overview of the software package has been written by project manager Bill Norton and lead architect Andy Adams, and appears in the July ConneXions (Vol. 10 No. 7). Norton gave a talk about NetSCARF and Scion at the Network Management Area Open Meeting at the Montreal IETF (June '96) and at a network statistics BOF following the May NANOG meeting. A new mailing list, netscarf@merit.edu, is a forum for community discussion and input to the project. Further information is available at the URL above. Susan R.

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 0016kokty.org.cn
