- Description of Working Group:
-
- The objective of this group is to decide how to best address known
- problems in existing implementations of the current TCP standard(s) and
- practices. The overall goal is to improve conditions in the existing
- Internet by enhancing the quality of current TCP/IP implementations. It
- is hoped that both performance and correctness issues can be resolved
- by making implementors aware of the problems and their solutions. In
- the long term, it is felt that this will provide a reduction in
- unnecessary traffic on the network, the rate of connection failures due
- to protocol errors, and load on network servers due to time spent
- processing both unsuccessful connections and retransmitted data. This
- will help to ensure the stability of the global Internet.
-
- Examples of detected problems:
-
- o TCPs that retransmit all unacknowledged data at a single time.
- This behavior greatly adds to Internet load, at a time when
- the network is already under stress. The combination can
- lead to congestion collapse.
-
- o TCPs that misinitialize the congestion window, leading to
- potentially enormous bursts of traffic when new connections
- begin. Such burstiness can greatly stress Internet routers.
-
- In the BOF, it was generally agreed that problems of this class need
- to be fixed.
-
- Scope:
-
- The scope of this group must be carefully defined in order to ensure
- timely progress. To this end, TCP issues that still remain areas of
- research are considered out of scope for the WG. For example new
- improvements in congestion control algorithms are not within the WG
- scope. The WG will solicit input from the End-To-End research group of
- the IRTF on questions of whether a TCP implementation issue is
- considered research.
-
- The major objectives of this group will be to :
-
- Produce a compilation of known problems and their solutions. This will
- raise awareness of these issues.
-
- Determine if any problems found are the result of ambiguities in the
- TCP specification. If necessary, produce a document which clarifies
- the specification.
-
- Catalog existing TCP test suites, diagnostic tools, testing
- organizations, and procedures that can be used by implementors to
- improve their code, and produce a document enumerating them.
-
-
- Goals and Milestones:
-
- Feb 97 Working group formation. Decide on document editors.
-
- Apr 97 Define schedule for producing the test suite catalog
-
- Apr 97 First Internet-Draft of problems and fixes, and very rough
- first draft of catalogue of test suites.
-
- Jul 97 Issue revised Internet-Draft documents.
-
- Sep 97 Cut-off for determining whether clarification document is
- needed. If necessary, have interim meeting to focus effort on
- clarification document.
-
- Dec 97 Submit Internet-Draft of test catalogue to IESG for publication
- as an RFC.
-
- Dec 97 Submit Internet-Draft of problems and fixes to IESG for
- publication as an RFC.
-
- Mar 98 Submit Internet-Draft clarifying RFCs 793, 1122, and 1323 to
- IESG for publication as an RFC.
-
- Mar 98 CLose WG down.
