- This is only a rough draft - Megan 04/10/92
-
- 23rd IETF meeting -- San Diego, CA
- Working Group on Internet School Networking
- March 17, 1992 1:30 -- 3:30 p.m.
-
- Co-Chairs: Art St.George (present),
- stgeorge@bootes.unm.edu; Connie Stout,
- connie.stout@tenet.edu; John Clement (present),
- clement@educom.edu
- General mailing list for ISN-WG: isn-wg@unmvm.unm.edu
-
- A list of those attending the session is appended to this
- document.
-
- Minutes
-
- Specific discussion around the major agenda topics is
- summarized below in sections 1) and 2). A number of
- general issues were addressed during the meeting, and are
- summarized briefly first.
-
- Joyce Reynolds <jkrey@isi.edu> mentioned that there is
- considerable interest in international circles, especially in
- Europe, in what this working group is doing, and that
- products from the WG will be scrutinized attentively
- overseas.
-
- Among the more general issues (exceeding technical
- boundaries) raised at least briefly during the session were:
- the need to provide persuasive arguments for educators to
- use with school administrators, to support both initial access
- and expansion of networking capabilities; the continuing
- need for postsecondary institutions to remain involved in
- helping schools with connectivity, whether as sources of
- guest accounts, for technical expertise and support where
- other mechanisms are not yet in place, or as sources of
- collaboration on connectivity or content problems.
-
- The issue of having the ISN-WG contribute to providing
- technical consulting capabilities to K-12 groups and
- institutions was discussed briefly. Although no definite
- resolution was offered, after the meeting it was suggested
- that a roster of persons willing to respond to technical
- questions might be prepared and offered as part of the FAQ
- resource (cf. item 2) below), with the possibility that these
- individuals might provide further technical consultation.
- One condition of listing in the roster would be that good
- questions to roster members would be added by them to the
- FAQ list.
-
- Denis Newman <dnewman@bbn.com> offered that there are
- many more (both local- and wid-area) networks in place in
- schools for administrative uses than there are instructional-
- use networks. He stipulated that, if administrative
- networks can be linked into the Internet -- as FIRN is in
- Florida -- overall connectivity can be substantially advanced.
- Denis suggested that the working group examine the issues
- involved in extending administrative LANs and WANs for
- instructional use; in particular, the group might consider
- addressing security questions, and look at the reality of risks
- entailed in carrying administrative and instructional traffic
- over the same networks, especially ways to minimize the
- risk of unauthorized access.
-
- 1) Review of connectivity alternatives and growth paths.
- Mailing list for this discussion: connect@unmvm.unm.edu
-
- A draft document prepared by Pat Burns and Ed Zachmann
- of Colorado State University (available on connect archives
- in Postscript format, or contact Art St.George for fax) was
- distributed to attendees, and served as a basis for extensive
- discussion during the meeting.
-
- John Clement presented a networking growth path from the
- viewpoint of educator practices. Ensuing discussion pointed
- out that the Burns and Zachmann paper lacked an initial
- connection model, what might be called Level 0 (the present
- paper begins with Level 1).
-
- Burns and Zachmann's Level 1 connectivity models (cf.
- especially Figures 3a and 3b) led to a consensus that both
- figures and their explanatory text needed relatively minor
- but significant revisions.
-
- Extensive discussion of the need for continued connection
- capability for the existing base of computers in schools (often
- machines of reduced capacity) led to an expressed consensus
- that such capability should be maintained in the near future
- (under Level 0 connection options), but should be eliminated
- over time as more advanced connection levels predominate.
- The minimum hardware capability for full Internet access to
- be supported would be Apple Macintosh machines or MS-
- DOS machines running Windows.
-
- Joe Blackmon <blackmon@ncsa.uiuc.edu> summarized his
- experiences in putting together full (56kbps) Internet
- connections for finalist schools in the SuperQuest
- competition at lowest possible costs, and offered to share a
- document he is preparing for SuperQuest on the subject.
-
- Discussion of Levels 2-4 (Figures 4-6 of Burns and Zachmann
- paper) connection models was relatively brief. There
- seemed to be general agreement that, on first reaction (most
- attendants were seeing the paper for the first time at the
- session), the models were acceptable with relatively minor
- corrections, although considerable extension and
- clarification were requested (see below). One point made
- was that the models as presented in the paper were
- overspecified with regard to their technical components, for
- the level of generality needed for a paper on connectivity
- alternatives. At the very least, mention should be made of
- other technical alternatives.
-
- [This was in no way presented as a criticism of the Burns and
- Zachmann paper, since they offered a starting point and it
- was appropriate to list a complete technical implementation
- so as to estimate costs. But perhaps it could be presented as
- one example.]
-
- Among the points raised that implied expanding the
- descriptions of the models:
-
- o guidance on the boundaries of application of each
- model: when each becomes inappropriate in given school
- contexts. For example, model 1 might apply to 3-8 machines
- in a school, and would not work for more than eight
- machines.
-
- o specification of what kinds of Internet capabilities are
- available for each model: i.e., model 1 offers telnet (remote
- login) via an interface menu item, but no direct telnet
- capability, and would allow access to WAIS via Simple
- WAIS but not the installation of WAIS client software, etc.
-
- o more complete specification of what is required at the
- Internet node/connection point for each model;
-
- o cost estimates for moving from one model to the next,
- and stipulation of what equipment would be no longer
- needed and could be used elsewhere;
-
- o specification of personnel, time and training
- requirements for installation, support (including time for
- administration and security protection), and maintenance.
-
- Jeff Hayward (jhayward@utexas.edu--ART I'M NOT SURE
- THIS ADDRESS IS RIGHT, DOING IT FROM MEMORY
- AND WHOIS IS NO HELP..) agreed to lead an effort to
- respecify the models on the basis of the Burns and
- Zachmann paper and its discussion, and to amplify their
- written description, and to prepare a draft before the end of
- the IETF meeting if possible.
-
- It was agreed that a revised draft document would be made
- available on <connect@unmvm.unm.edu>, and that it would
- be revised once more from feedback on the list. A twice-
- iterated draft might be available in advance of the Twenty-
- Fourth IETF, in Boston in July.
-
- 2) Development of an FAQ ("frequently-asked-questions)
- archive on school connectivity issues. A new mailing list
- will be formed for this issue
-
- Discussion initially focused on identifying sources of
- information and materials from which a set of FAQs and
- candidate answers might be developed. KIDSNET and
- EDTECH lists were mentioned, and there are many others.
- A number of attendees offered to help round up relevant
- materials:
-
- Gene Hastings <hastings@psc..edu>
- Peter Deutsch <ART, DO YOU HAVE HIS EMAIL
- ADDRESS?>
- Rob Reilly <rreilly@athena.mit.edu>
-
- Art St. George and John Clement offered to assemble the
- materials located into a preliminary archive.
-
- Volunteers were solicited to edit the archive and
- review/revise answers to the questions. The following were
- dragooned into volunteering:
-
- Tony Rutkowski <amr@nri.reston.va.us>
- Joe Blackmon <blackmon@ncsa.uiuc.edu>
- Tracy LaQuey <CURRENT EMAIL, PLEASE?>
- Michael Marcinkevicz <mdm@csu.net>
-
- John Clement will also ask Al Rogers of FrEdMail to
- volunteer or suggest one of the FrEdMail sysops to
- volunteer.
-
- By the next IETF meeting, it was agreed that a preliminary
- FAQ archive would have received an editing pass and
- would be available for examination and revision.
-
- The following preliminary set of categories is offered for
- consideration for the FAQ list:
-
- o why should K-12 educators and schools connect to the
- Internet?
- o modes of access
- o costs
- o support issues, including maintenance, access rules,
- security
- o sources of information
- o troubleshooting
- o glossary of essential terms
- o technical specifications
- o technical consultants roster: people willing to respond
- to questions, or possibly provide further consultation
