- Area Summary reported by Dave Piscitello/Bellcore and Erik
- Huizer/SURFnet
-
- The OSI Integration Area of the IETF is attempting to bring OSI to the
- Internet. OSI applications, especially The Directory, offer features
- that are necessary to sustain the astonishing growth of the Internet;
- Message Handling Services and Office Documentation offer features that
- are both new and complementary to existing Internet applications.
- Working groups in the IETF, in collaboration with RARE working groups,
- continue to experiment with and deploy these applications in production
- networks, over OSI as well as TCP/IP.
-
- During the early deployment of OSI applications, hybridization of OSI
- and TCP/IP was necessary and has proven to be useful in obtaining
- experience and acceptance for OSI. Experimentation with OSIs transport
- services is important as well; the continued efforts of the NOOP Group
- to expand CLNP connectivity across regional and international networks
- may well prove essential to the growth of the Internet. Currently, this
- effort requires hybridization of a different sort: SNMP management over
- OSI is as desirable here as X.500 over TCP/IP. For this reason, and the
- more far-reaching need to integrate additional protocols and
- architectures into the Internet, the first multi-protocol Working Group
- was formed under the joint directorship of the SNMP and OSI Integration
- Areas. Based on the success of the Working Group, it may not be the
- last of its kind.
-
- Introduction
-
- The OSI Integration Area currently consists of the following working
- groups, (working group Chairs/affiliation in parentheses):
-
-
- o Network OSI Operations (Sue Hares/Merit)
- o X.400 Operations (Alf Hansen/SintefDELAB, Rob
- Hagens/Univ.Wisconsin)
- o OSI Directory Services (Steve Hardcastle-Kille/UCL)
- o Office Document Architecture (Peter Kirstein/UCL)
- o MHS-DS (Kevin Jordan/CDC, Harald Alvestrand/Sintef DELAB)
- o SNMP over a Multiprotocol Internet (Theodore Brunner/Bellcore)
- o OSI General (Ross Callon/DEC)
-
-
- The DISI Working Group, in the User Services Area, also has strong ties
-
-
- 1
-
-
-
-
-
- into the OSI Integration Area.
-
- The following BOFs related to the OSI Integration Area were held in San
- Diego:
-
-
- o MIME to MHS Mapping BOF (Marshall Rose/DBC)
- o Wais and Directory integration (Steve Hardcastle-Kille/UCL)
-
-
- Network OSI Operations Working Group (NOOP)
-
- The NOOP Group continues work towards compiling a compendium of OSI
- support -- applications and in particular, support of CLNP -- in
- regional networks. The existing questionaire was reviewed and revised.
- Work continues on the compilation of a list of available OSI diagnostic
- tools (Tools RFC), and requirements for OSI support in the SNMP. The
- Working Group heard presentations from John Curran of NEARNet (New
- England Academic & Research Network) and Steve Deering NEARNets on OSI
- NSAP address assignment plans. Work continues as well on the Security
- RFC, in particular, on an OSI Packet Filtering document that discusses
- the issues associated with filtering OSI by application type in the
- context of using packet filtering to restrict OSI connections (i.e., to
- establish firewalls).
-
- The Working Group is investigating sharing test suites and coordinating
- test pilots with RARE, especially for inter-domain routing and
- applications.
-
- X.400 Operations Working Group (X400OPS)
-
- The composition of the Working Group that met in San Diego illustrates
- the increasingly international flavor of the IETF. Among the 29
- participants were 7 Europeans and 3 Koreans.
-
- The routing coordination document has been reviewed again and was now
- judged suitable for submission as an experimental (or if possible as a
- prototype) RFC.
-
- Three other documents are still under discussion and need another round
- of review:
-
-
- o ``Operational Requirements for X.400 Management Domains''
- o ``Mapping between X.400 (1984/1988) and Mail-11 (DECnet mail)''
- o Use of DNS to store RFC -987 mapping data
-
-
- Experiments with the protocols described in these last two drafts are
- under way.
-
- The Working Group will produce several documents in the very near term,
-
-
- 2
-
-
-
-
-
- including:
-
-
- o Minimum Level of Service
- o Table update procedures
- o National Character set usage in X.400
-
-
- In addition, two documents in the standards track are under review by
- the IESG/IAB and on the verge of becoming proposed standards:
-
-
- o ``X.400 1988 to X.400 1984 downgrading''
- o ``Mapping between X.400(1988) / ISO 10021 and RFC 822''
-
-
- During the Working Group session, there was an extensive discussion on
- MHS communities. Noteworthy was that there was participation from a
- public service provider.
-
- OSI Directory Services Working Group (OSIDS)
-
- The Working Group met in San Diego with the following results:
-
- Several documents were reviewed and are to be submitted to the IESG for
- consideration a draft RFCs:
-
-
- o ``Naming Guidelines for Directory Pilots''
- o User Friendly Naming
- o String representation of Distinguished Names
-
-
- Experiments continue (and reports were given) in the following areas:
-
-
- o Quality of service parameters
- o JPEG photo attribute
-
-
- New experiments to be started:
-
-
- o European character sets in X.500
- o DIT counting
-
-
- Other noteworthy decisions and discussions:
-
-
- o Naming Schema document maintenance is now moved to a small
- committee
- o The naming schema document will be restructured
-
- 3
-
-
-
-
-
- o Discussion on deployment of DNS through X.500
- o O=internet will be put directly under the root
- o Discussion on registration vs Listing
- o Discussion on Skinny OSI stack, Lightweight protocols and Simple
- OSI Stack.
-
-
- Office Document Architecture Working Group (ODA)
-
- The ODA Working Group met at San Diego with the following results:
-
- It was reported that 5 Implementations are available and under test. So
- far these implementations run only on top of X.400. Service is to be
- launched during next few months.
-
- MHS - DS Working Group (MHSDS)
-
- This Working Group met for the first time in San Diego.
-
- There were two input documents:
-
-
- o PP use of directory Services (implementation specific)
- o The ISO proposal on this issue.
-
-
- After an extensive debate, it was proposed that seven documents be
- drafted based upon the PP input document:
-
-
- 1. Table and tree handling by DS
- 2. O/R name representation as Distinguished Name
- 3. Routing info in DS
- 4. X.400/822 mapping tables in DS
- 5. tMailing list expansion using DS
- 6. RFC-822 routing based on DS
- 7. Simple application profile
-
-
- The next Working Group meeting will be in Innsbruck, Austria in May
- 1992.
-
- SNMP over a Multiprotocol Internet Working Group (MPSNMP)
-
- The Working Group was chartered with defining the mapping and SNMP
- encapsulation for three transport domains -- OSI, Appletalk, and
- XNS/IPX. Since it was envisioned that at a future time, additional
- transport domains might be identified, the Working Group agreed to
- produce a how to RFC, identifying a checklist of issues to consider in
- specifying an encapsulation of SNMP.
-
- The Working Group considered three existing documents:
-
- 4
-
-
-
-
-
- o The informational RFC 1298, entitled ``SNMP over IPX'',
- o The internet draft (draft-ietf-appleip-snmp-00.txt) entitled ``SNMP
- over AppleTalk''
- o The experimental RFC 1283, entitled ``SNMP over OSI''
-
-
- In all cases, the committee determined that a connectionless TS similar
- to UDP was desirable (architecturally appropriate). Security, maximum
- packet size, and addressing considerations for each transport domain
- were discussed. Authors of each of the documents were present, and
- agreed to make appropriate changes, and further agreed to post the
- documents to the mailing list for a three week review. If a consensus
- is reached following the posting period, the Working Group agreed that
- the three SNMP over foo documents be submitted to the IESG for
- consideration as draft RFCs.
-
- OSI General Working Group (OSIGEN)
-
- This Working Group did not meet in San Diego.
-
- The Area Directors will propose that this Group will disband.

-
- MIME to MHS Mapping BOF (MIMEMHS)
-
- There were two input documents for this BOF on mapping between MIME and
- X.400. A third one was announced but not tabled.
-
- There was a consensus that the mapping could be easily constructed for
- some of the bodyparts and not be constructed for others. It was
- therefore proposed to create a short lived Working Group to create two
- documents:
-
-
- o Basic mapping
- o Specific bodypart mapping
-
-
- This deals with an initial set of registered conversions. The
- registration will have to be maintained.
-
- WAIS and Directory Integration BOF (WAIS)
-
- This meeting followed discussion at the ``Living Documents'' BOF the
- previous evening, and was more focussed in its discussion.
-
- The WAIS, World-Wide Web, Prospero systems for network information
- retrieval (NIR) were presented (the Gopher protocol was presented in
- plenary the following day). The X.500 Directory was presented in the
- light of NIR needs, as were two proposals to use the directory to refer
- to documents. A discussion followed as to how to allow these systems to
- interoperate, and on requirements for name spaces. A working group was
- proposed to define the format for a generalized printable format for a
- name or address in any of these systems.
