- MINUTES
-
- The meeting was convened by co-chairmen Ross Callon and Rob Hagens. An
- attendance list will be published with the Proceedings of the IETF.
-
- A series of brief status updates on the following topics were presented:
-
-
- o BSD 4.4: An ISODE/BSD interface has been constructed and tested.
- Alpha copies have been distributed to a small number of sites.
- Work is still in progress fixing bugs, testing, etc.
- o New revision of RFC 1069. The newest version of RFC 1069,
- compatible with the GOSIP V2 (if the OSIIWG comments are accepted)
- has been prepared. Its submission to the RFC editor will be
- delayed until GOSIP V2 is released.
- o The ECHO RFC has been released as an Internet Draft. This RFC
- specifies how to implement an ECHO facility with ISO 8473. The WG
- reviewed the document and found (with 2 minor editing changes) it
- ready to be sent to the RFC editor.
- o There is no official word from NIST regarding the OSIIWG GOSIP V2
- comments. A representitive of the OSIIWG will attend the next
- GOSIP Advanced Requirements Committee meeting.
- o GSA has a contract to administer ICD 0005 (although NIST still
- maintains authority). The DCA use of 0006 is unknown. NIST
- currently supports the use of 0005 by the entire Internet.
- Policies for the use of 0005 have not yet been established. Those
- with strong interests in future policy should contact:
-
- Mr. Gerard F. Mulvenna
- Technology Building, Room B-217
- National Institute of Standards and Technology
- Gaithersburg, MD 20899
-
- Dave Katz presented his OSI experiences at Interop, 89.
-
- Rick Wilder presented preliminary results of the MITRE congestion
- avoidance experiments.
-
- Following this, the state of the OSIIWG was discussed. A list of new
- working groups that need to be formed was presented. This list includes
- the reorganization of the OSIIWG into the OSI-General WG.
-
- Note: the OSI-RA group may be split into two separate groups, one to
- produce NSAP administration guidelines, and the other to follow upper
- layer registration policy.
-
- Finally, the list of current and future work of the OSI Area was
- presented:
-
-
- IETF OSIIWG STATUS/Callon and Hagens
-
-
- Agreements and future work of the IETF OSIIWG

- DRAFT
-
-
- 1. Physical Layer
- (a) Accomplishments and Agreements
- o None identified.
- (b) Future Work
- o None identified.
- 2. Link Layer
- (a) Accomplishments and Agreements
- o None identified.
- (b) Future Work
- o Distinguishing packets on the wire
- o HDLC
- o X.25
- 3. Network Layer
- (a) Accomplishments and Agreements
- i. Data transfer
- oISO 8473/use as specified
- ii. Routing
- oISO 9542/use as specified
- oIntra-domain routing/use ANSI IS-IS as presented as
- draft proposal
- use ANSI IS-IS as presented as draft proposal.
- oInter-domain routing use static tables.
- iii.ISO 8473 Echo
- A draft RFC has been prepared. It describes an echo
- function that is realized by defining a new network
- selector that indicates an echo entity. This is
- backward compatable with existing 8473 packets.
- iv. NSAP address format
- oRFC 1069 RFC 1069 has been updated to align with the
- GOSIP V2 NSAP address format.
- oNSAP Selectors OSIIWG comments on GOSIP V2 recommend
- that GOSIP V2 should not specify the format of the NSAP
- selector value.
- (b) Future Work
- i. ISO 8473 Echo
- Initiate a new ANSI X3S3.3 work item to propose a
- CLNP echo function to ISO. This echo function is
- realized by defining a new protocol type field. This
- is not backward compatable with existing 8473
- packets.
- ii. NSAP address format
- oNSAP Administration Design and write procedures for
- administering NSAP address heirarchies.
- oICD Usage Determine whether the Internet should register
- under ICD 0005 or ICD 0006 or both. Coordinate with any
- previous NIST/GSA agreements, or motivate new
- agreements.
- iii.CO/CL
- We should track the CO/CL interworking status in
- X3S3.3.
- 4. Transport Layer
- (a) Accomplishments and Agreements
- Recommend that GOSIP V2 mandate NIST agreements
- regarding congestion recovery algorithms and related
- retransmission timer algorithms.
- (b) Future Work
- None identified.
- 5. Session Layer
- (a) Accomplishments and Agreements
- None identified.
- (b) Future Work
- None identified.
- 6. Presentation Layer
- (a) Accomplishments and Agreements
- None identified.
- (b) Future Work
- None identified.
- 7. Application Layer
- (a) X.400
- i. Accomplishments and Agreements
- oPRMD name
- The intended use of "NREN" as a PRMD name is to identify
- a management domain within which every registered
- Internet entity has a default X.400 Address. This
- address would be based upon the Internet domain name.
- We expect some or all currently registered entities to
- decide for them- selves whether they wish to use the
- default or register another name in another way. This
- default provides a useful and helpful option without
- constraining any individual entity to keep what the
- default provides for them.
- ii. Future Work
- A.GOSIP V2
-
- Work with the GOSIP user's group to rewrite the X.400
- ORAddress section.
- B.822 <-> X.400 gateway operation
- o Table Maintenance
- o Locating a Gateway
- o ORAddress Structure
- C.X.400 operation
- o Default naming
- o Taxonomy of issues Write a memo which describes the
- needs of X.400 addressing, X.400/RFC 822 address
- mapping, and utilization of an X.500 directory
- service. (In Progress).
- (b) Registration and Naming
- i. Accomplishments and Agreements:
- See "NREN".
- ii. Future Work
- oNSAP administration See NSAP administration under
- Network Layer.
- oNSAP and ORAddress relationships Explore the
- relationship between NSAP addresses and X.400
- ORAddresses. Should the NSAP address field
- "oganization" under ICD 0005 be used in the X.400
- ORAddress "organization" field to reduce administration
- complexity?
- oEstablishing Ownership Identify necessary steps we must
- take to assert that the name "NREN" belongs to the
- FRICC.
- (c) Directory Services
- i. Accomplishments and Agreements
-
- None.
- ii. Future Work
- A.X.500 and Internet DNS
-
- Explore coexistence/interactions between X.500 and the
- Internet DNS
- B.Missing Pieces
-
- Locate missing pieces required by a production system
- (format of objects, choice of dis- tinguished names,
- etc.)
- C.Requirements of a dual protocol internet
-
- o Application Gateways Identification of application
- gateways needed for communication between
- heterogenous, pure stack hosts. In addition, support
- for the deci- sion to gateway (i.e., forward as X.400
- message or translate into RFC 822).
- o Stack Choice Identification of optimal protocol stack
- choice for dual hosts (based upon the destination sys-
- tem).
- (d) VTP
- i. Accomplishments and Agreements
-
- None
- ii. Future Work
-
- Look for problems with Telnet/VTP interaction.
- (e) FTAM
- i. Accomplishments and Agreements
-
- None
- ii. Future Work
-
- Look for problems with FTAM/FTP interaction.
- (f) Network Management
- i. Accomplishments and Agreements
-
- None
- ii. Future Work
-
- oCMIP
- oOSI MIB
- 8. General Future Work
- (a) Mixed Stack
-
- GOSIP prohibits a mixed stack approach. Do mixed stacks have
- enought merit that they should be allowed?
- (b) Mixed Technology
-
- Can OSI problems be solved with internet technol- ogy? Will
- the Internet incorporate OSI technology? For example, can
- X.400 routing utilize the DNS, in the absense of X.500?
- (c) Document Review
- o GOSIP
-
- o ANSI specifications
- o FRICC Multi-Protocol Implementation Plan
