- meeting in Brussels, Belgium:
-
- OVERVIEW
-
- P1003.8 is the IEEE POSIX networking standards committee, working on
- network standard interface definitions for POSIX. The committee is
- currently divided into six subcommittees: transparent file access,
- network IPC, remote procedure call, OSI/MAP services, X.400 mail
- gateway, and directory services.
-
- This report is a summary of the activity in the network IPC
- subcommittee, which is currently working on two potential interfaces,
- a "detailed" interface (DNI) and a "simple" interface (SNI). DNI is
- roughly (though not exclusively) at the transport level. SNI is
- intended to be somewhat simpler to use than DNI, but at roughly the
- same level.
-
- At this meeting, presentations of DNI and SNI were made at the EC
- (European Community) headquarters in Brussels. Discussions on DNI
- (definitions) and SNI (routines) continued. The main topics of
- discussion were:
-
- 1. DNI, SNI presentation to EC
-
- 2. DNI definitions
-
- 3. SNI routines
-
- 4. Schedule
-
- 5. Security

-
- DETAIL
-
- 1. DNI, SNI presentation to EC
-
- Keith Sklower and Steve Head gave presentations on DNI and SNI
- respectively to POSIX attendees at CEC (Commission of the
- European Community) headquarters. This meeting was scheduled in
- Brussels primarily to obtain European input. The presentations
- went well, and attendees included X/Open and EC representatives.
-
- No significant differences of opinion or direction were noted
- between the committee and other attendees. This indicates some
- degree of success (?). (Other networking groups, such as
- directory services, were not so fortunate.)
-
- This meeting "broke the ice" with international organizations in
- the area of networking, and we now expect increased interaction
- with those organizations.
-
- 2. DNI definitions
-
- The committee discussed DNI definitions. Steve Head presented a
- paper on the subject. Suggestions made at the meeting will be
- incorporated into a future version of the paper, which will be
- circulated via electronic mail. If no further significant
- issues are raised, it will be incorporated into the next DNI
- draft.
-
- 3. SNI routines
-
- The committee discussed SNI routines, based on a paper from
- Keith Sklower. No conclusions were reached, however, this
- particular discussion was very useful since it brought a number
- of goals and requirements for SNI into clear focus.
-
- SNI is adopting some characteristics of ISODE (the ISO
- Development Environment). This is probably beneficial since it
- means that SNI will be partially based on a working
- implementation instead of being entirely new. As such, it may
- gain importance as a migration strategy for transferring
- applications from TCP/IP to ISO. (ISODE stands for the ISO
- Development Environment, a collection of networking software
- available through public channels that runs over either TCP/IP
- or ISO transport and allows higher level applications to be

-
- oblivious to the type of transport a given system provides.)
-
- 4. Schedule
-
- The working schedule has been delayed by the need to make
- presentations at Brussels, instead of doing "real work".
- Originally, we had scheduled the topics of connection setup,
- connection tear-down, and name resolution for this meeting.
- These topics were not discussed, and our schedule has been
- shifted back a quarter to reflect this. These topics will be
- discussed at the next meeting. (See FUTURE MEETING TOPICS
- below.)
-
- 5. Security
-
- We held another joint meeting with the POSIX security group,
- P1003.6. An electronic mailing list was created for the topic
- of network security. For more info or to be put on the list,
- please contact Mike Ressler (mpr@bellcore.com or bellcore!mpr).
- A list of topics on networking security to begin discussions on
- was initiated.
-
- 6. P1003.8/2 -> full POSIX committee
-
- The decision to make P1003.8/2 a full POSIX committee was
- postponed by the POSIX executive committee (SEC). This subject
- will be re-addressed at the next POSIX meeting in January.
