- Editor's Note: Minutes received 7/27
-
- CURRENT_MEETING_REPORT_
-
-
- Reported by John Clement/EDUCOM/CoSN
-
- Minutes of the Internet School Networking Working Group (ISN)
-
- The Agenda had two items: connectivity models, and development of an
- FAQ archive. A third item was introduced by Scott Williamson:
- developing a recommendation on domain naming schemes for K-12 schools
- and organizations.
-
- We reviewed connectivity alternatives and growth paths. The mailing
- list for this subtask is connect@unmvma.unm.edu. We began by a brief
- review of a number of documents (of varying formality and draft status)
- on topics related to connectivity for schools.
-
- Newman, Denis, Susan Bernstein and Paul A. Reese. Local Infrastructures
- for School Networking: Current Models and Prospects. BBN Report No.
- 7726, April 1992. Available in hardcopy from Bank Street School of
- Education and by ftp from nysernet.org.
-
- Susan Bernstein presented major findings of this report. She made it
- clear that the report was not itself about connectivity alternatives
- themselves, but about the current situation in school networks and
- machine- (or LAN-) to-WAN connectivity. Many schools have LANs, and
- many have WANs; but the latter are almost exclusively used for
- administrative (not instructional) purposes; and the instructional LANs
- are not connected to the available WANs, and indeed often instructional
- LANs are dedicated to Individualized Learning Software (ILS) systems,
- using proprietary network protocols. The terminal-host model is almost
- entirely what is currently used for school-to-WAN connection.
-
- The paper recommends a possible growth path from the point of individual
- dialin connections from a machine to a host resource, a path that does
- ``..not assume the initial availability of LANs but begin(s) developing
- the expertise and the software to support true network connections in
- schools with stand-alone computers..'' (p.34). The path would lead
- schools through connections to a remote network, to a leased line to a
- local Internet node, and finally to a local Internet server.

- Light at the End of the Tunnel May be an Oncoming Rain! Unpublished
- manuscript, July 1992. Available by request from
- rreilly@athena.mit.edu.
-
- Rob Reilly sketched the main points of his paper as emphasizing the need
- to deal with both the physical network and the logical one; a synopsis
- of connectivity models within one overview structure; and process
- suggestions for future steps.

-
- Hastings, Eugene. Connectivity Models for Internet Access. Version
- 1.1. Monday, July 13, 1992. Unpublished manuscript. Available by
- request from hastings@psc.edu.
-
- Gene Hastings' paper begins with the presumption that one is connecting
- networks together. He calls for schools to build school-specific
- infrastructures (up to a consortium of school districts) and then
- connect in bulk to the Internet.
-
- His models address needs and constraints of connectivity situations in
- different situations -- for example, in some areas telephone tariffs are
- based on metered but untimed calls. In others, the near future will
- bring ISDN capability -- in the Bell Atlantic market, perhaps for as low
- as $40/month.
-
- Pricing models are not yet set; there is a chance for user communities
- such as schools to affect these decisions. However, many of the
- connection options are currently being priced as extra-cost luxury items
- for small customers, which is exactly the wrong approach.
-
- Discussion then began of the various models and designs presented.
- Susan Bernstein pointed out that the model outlined by Reilly and Lidl
- was, even in its fullest expression, not yet a ``local Internet server''
- model, but relied on a leased-line connection to an external host
- machine, itself on the Internet. For a long-term solution to the
- problem of connecting K-12, we have to migrate Internet and other
- servers to the school settings.
-
- Brian Lloyd mentioned work he was doing in the Bay Area to connect two
- schools, as well as preparing a paper for BARRNET on methods. He
- reported that he was obtaining old PCs and installing them as routers
- using PPP. He envisions, he said, a three-phase process: in phase 1 a
- connection to a school is provided, but (the campus or regional -- some
- already-connected group) carries the technical and administrative load;
- in phase 2, the school learns to manage its own access to the network;
- and in phase 3 the school provides a name and file server for a group of
- schools.
-
- Gerry White of Applitek mentioned that his company is exploring
- providing broadband Ethernet connectivity to schools via installed
- cable. An unspecified number of the nation's school cable plants have
- ``backchannel'' capability, which will allow interactive uses. A number
- of concerns were expressed with issues such as tuning and management of
- broadband over cable, with ghosting and interference and their impact on
- packet transmission; but there was consensus that such models were well
- worth exploring and noting in an RFC draft.
-
- Eric Hood of NorthWestNet and FARNET K-12 asked that any analysis of
-
- 2
-
-
-
-
-
- models consider costs of network management.
-
- Michael Powell of Pacific Bell mentioned that his company has entered an
- agreement with California State University and the California Technology
- Project to provide gateways for an Internet connection to every educator
- in the state, under the name Knowledge Network. They are eager to
- participate in the process of developing connectivity models.
-
- John Clement offered that there seemed to be enough written, and enough
- areas of general agreement between the different documents, that one
- could now attempt a draft RFC. He asked for volunteers, and said there
- would be a document posted for discussion before IETF 25 in Washington
- DC (dates??). The following individuals volunteered:
-
-
- Rob Reilly, Lanesboro, MA Schools (first draft synthesizer)
- Susan Bernstein (reviewer)
- Eugene Hastings, Pittsburgh Supercomputer Center
- Ellen Hoffman, Merit Network Inc.
- Brian Lloyd and Constance Lloyd, Cameron Park, CA
- Michael Powell, Pacific Bell
- Gerry White, Applitek
-
-
- Development of a FAQ (``frequently-asked-questions'') archive on school
- connectivity issues. The mailing list for this subtask is
- faq@unmvma.unm.edu. It was mentioned that Ed Vielmetti of CICnet has
- installed the Kidsnet archives on a WAIS server. The resource seems
- likely to provide useful ``first answers'' for an FAQ file.
-
- John Clement offered to use the cosndisc (Consortium for School
- Networking) discussion forum to develop a set of questions. April
- Marine of SRI and Jennifer Sellers of NASA then offered to draft answers
- to the questions using the Kidsnet WAIS resource. It was agreed that a
- draft FAQ file could be made available by the time of IETF 25 in
- Washington, DC.
-
- Developing a recommendation on domain naming schemes for K-12 schools
- and organizations. A discussion was introduced by Scott Williamson of
- ISI. An increasing number of requests are being received for K-12 domain
- names, and there is no agreed- upon naming structure. The prospect of a
- very large number of K-12 domains and nodes raises serious concerns.
-
- Discussion points raised: already existing are names such as xxhs.edu.
- Expansion of this model will provide a very flat structure with very
- little information, and offer a lot of chances for conflict over names
- (there are a large number of George Washington or Martin Luther King,
- Jr. high schools).
-
- Additionally, although elementary schools and high schools are
- identified with relative clarity, there is considerable ambiguity in the
- middle range (middle schools, intermediate schools, junior high
- schools). Finally, the point was raised that this information is of
-
- 3
-
-
-
-
-
- uncertain value for a naming domain.
-
- Considerable discussion was held on the notion of a geography- based
- naming convention within the .us domain. Ellen Hoffman of Merit
- Network, Inc. offered to prepare a draft document for discussion on
- this issue.
-
- The general mailing list for this discussion is isn-wg@unmvma.unm.edu.
- Copies of the papers cited, can be had by asking John Clement
- <clement@educom.edu>. Reactions and comments are much appreciated.
