FOREWARD
The meeting agenda will be found in Appendix A. The attendees were:
IESG Members:
FNC Visitors:
Scribe:
These minutes were prepared by Greg Vaudreuil of CNRI and edited by Vint Cerf, Chair of the IAB, and by Bob Braden, the IAB Executive Director (ExecD). We have endeavored to accurately reflect the content and thrust of the discussions. Although the IAB has reviewed the results, we must take responsibility for any unintentional misrepresentation.
Vint Cerf welcomed Christian Huitema of INRIA, France as the newest IAB member.
Action Items from earlier meetings were reviewed; the disposition will be found in Appendix B. The discussion led to the following new actions:
NEW ACTION: Gross: Document Terms of Reference of IEPG.
NEW ACTION: Lauck: Publish ANSI's registration procedures for OSI.
Lauck summarized the major issues in testability of protocols:
Subsequently, NSF agreed to consider for sponsorship any networks that wish to be registered under the RFC-1174 rules. NSF cannot provide a "blanket" sponsorship, since each instance has to be validated against existing US government policies. Once the pro- curement action has been completed, the implementation of RFC-1174 will be somewhat easier, since the global Internet registry func- tions now performed by the DDN NIC will have been separated from the DDN registration functions to be performed under the new contract. The details of implementation are still being worked out, but the IAB is confident that the matter is well in hand.
The IAB reaffirmed that the RFC-1174 registration process is necessary for global registration, to support an increasingly international Internet.
The OTA is conducting a computer moderated conference to gather information on NREN technology. Vint Cerf, who is a participant in the conference, reported that it totals some 60KB of messages per day! He has found that some of the information on the list is technically inaccurate, and he is not convinced that OTA is being well informed. It was the sense of the IAB that as recognized authorities on Internet technology, the IAB should contribute to the OTA effort. Several approaches were discussed, and the fol- lowing were agreed.
NEW ACTION: Cerf: (1) Send RFC-1167 to the OTA panel as a sub- mission on NREN. (2) Offer to comment on the final document when it is available.
The IAB discussed ways to acquire a better international perspective. It was agreed that the ITU Standards Summit Meeting to be held 11-13 March in Nice, France, is a good opportunity to call attention to our intention of making the Internet support both OSI and TCP/IP. The the IAB will be represented there by Dan Lynch and Lyman Chapin.
It was agreed that the IAB needs to:
The group discussed (3) in particular. Video and telephone confer- ences can be used, perhaps with the aid of BBN's mmconf software, in lieu of face-to-face meetings. The technical features of mmconf were discussed. Richer pointed out that Forsdick of BBN is working on ruggedizing mmconf and adding tablet support; he suggested waiting until July 1, 1991 to use it. There was some dismay that we have waited so long and tried so often to make progress in this area.
NEW ACTION: Kent: Discuss IAB needs with the mmconf group at BBN, and report on configuration requirements.
For the present, we will simply include Huitema in telephone confer- ence calls, setting the time to make it reasonable for him to parti- cipate.
NEW ACTION: Cerf & ExecD: Decide upon mode for April 3, 1991 meeting [DONE].
There is a more general problem with IPSO: for historical reasons, the IPSO is specific to the US DoD. A more general approach is required for commercial security and for international use. IPSO does include an extended security option, which in principle would allow arbitrary extensions, but DCA (as opposed to the IANA) currently assigns extended option numbers; this would be a problem for vendors using the protocol for their own purposes.
There is another security option in the works which promises to be more useful to commercial and international users; this is known as CIPSO (Commercial IP Security Option).
NEW ACTION: S. Crocker, Kent: Complete IPSO document and pub- lish is as an Internet Draft [DONE].
Steve Crocker pointed out that there will be a "start point", after which keys will be parmanent. This will happen when RSA creates the root certificate, from which all others are derived.
Huitema noted that there is a problem in France, where a World War I law prohibits encryption on any electromagnetic communication channel, except as allowed by the military. In practice, only banks and other financial institutions are allowed to perform encryption.
NEW ACTION: Kent: Revise his summary of the export control pol- icy, to include DEC comments.
The meeting did an excellent job of laying out the architectural issues and alternatives, but made little progress towards deciding on future directions. The group therefore decided to schedule a future 3-day "architecture workshop" for the IESG and IAB. All participants should come prepared with papers, and be prepared to compromise; get- ting an agreement is most important. This workshop is scheduled for June 11-13, 1991.
He presented the structure recommended by the IETF NSAP working group. The IETF group further proposed that regional networks be tasked to serve as addressing authorities for their client networks. NSAPS will be tagged to the regional to take advantage of hierarchy.
The issue was complex, and the IAB was unable to endorse the option chosen by the IETF working group without further consideration.
Major Issues:
The X.500 pilot program currently lists 13 countries, 400 organiza- tions, and 350,000 entries. Most of the current usage is lookup of US names. The goals of the X.500 effort in the Internet is to provide White Pages service, OSI applications support, and storage of security certificates.
There continue to be significant problems in the deployment of X.500, including missing standards for schema, replication, and security, and resolution of incompatible lower layers (1006/CLNP/X.25). The IETF is working on interim solutions for the missing elements of X.500. The group plans to identify holes, document solutions, and deploy on a large scale starting this year.
Kent pointed out the need for a definition of distinguished names for use in PEM. He will ask Steve Kille to check the PEM draft.
NEW ACTION: Kent: Ask Kille to review distinguished names as defined in PEM.
Several issues were raised.
Callon: yes; these differences stem from different basic assump- tions about the environment.
Huitema pointed out that IS-IS as applied in OSI handles a routing domain that is roughly equivalent to one subnetted class B IP net- work; as applied in TCP/IP, IS-IS is used for a much larger aggre- gation.
No conclusions were reached on these questions. However, the group agreed on the importance of setting an objective set of criteria for advancing a routing protocol towards a standard. Hinden agreed to draft such a list.
NEW ACTION: Hinden: Draft a set of criteria for advancing routing protocols to Draft Standard.
