- Minutes of the PktWay-WG meeting, at IETF'39, Aug-1997
- ======================================================
- (Reported by Marc Fidler and Mark Littlefield)
-
- The PacketWay working group met at IETF'39 in Munich, Germany on
- Friday, August 15. The list of attendees is attached.
-
- Danny Cohen opened the meeting by asking all attendees introduce
- themselves and provide their background.
-
- Danny next presented an overview of PacketWay and the meeting agenda that
- included:
- Status of the documents)
- PktWay and SRVLOC
- Interoperability testing
- MPI over PktWay
-
- Thomas Narten (AD-INT) iterated the need to accelerate the work on the
- various documents, which are the expected delivery of the PktWay-WG.
- Thomas also provided much needed guidance about various aspects of the
- required work.
-
- A number of document action items were discussed. The PacketWay
- specification is now split into multiple documents:
-
- 1. EEP The goal is to finish editing the document by the end of
- the month and submit for proposed standard status by the end of
- September, including a two-weeks last-call period.
-
- The EEP handling of destination-designation (using Hoffman Coding)
- has to be better explained than the way it is in the current document.
-
- The EEP document will have a new section about address assignment,
- which will be a recommendation, not a part of the PktWay standard
- (just as IP address assignment is NOT a part of RFC0791).
-
- 2. The enumeration appendix will be removed into a separate document,
- to be eventually maintained by IANA.
-
- 3. RRP This document will be split into three documents:
- a. Basic RRP
- b. Capability handling
- c. Dynamic routing table exchange
-
- The enumeration appendix will be removed from the RRP document and a
- separate document created as mentioned above).
-
- The goal is to submit the RRP documents for proposed standard status
- by the December IETF meeting.
-
- Marc Fidler and Robert George suggested to add to the PktWay standard
- also a "compressed header" of 8B only. The consensus was that such a
- compressed PacketWay header should be proposed in a separate document
- (probably as a new version of the EEP).
-
- Robert George proposed a certain format for the "compressed header"
- which he will circulate soon via a message to the mailing list.
-
- The following milestones were judged by the working group as realistic:
-
- Aug-97 EEP interoperability demo (done, between MSU and LMMS)
-
- Sep-97 Submit the updated EEP Internet-Draft as a Proposed-Standard
-
- Sep-97 Submit the RRP specification as an Internet-Draft
-
- Oct-97 Demo test interoperability of the RRP
-
- Nov-97 Submit the updated RRP as a Proposed-Standard
-
- Dec-97 (IETF-DC) Submit initial specification of the PktWay REDAP
- (Resource Discovery and Allocation Protocol) as an
- Internet-Draft
-
- Mar-98 Demo the PktWay REDAP
-
- Apr-98 Submit the updated REDAP as a Proposed-Standard
-
-
- Danny reported about the differences between SRVLOC and the way PktWay
- handles CAPAbilities. In spite of the differences, some coordination is
- planned between the two working groups. PktWay will add to its
- capabilities a SRVLOC-server, and some effort will be made to unify the
- capabilities code. Danny will work on it with Erik Guttman of SUN, the
- co-chair of the SRVLOC-WG.
-
- Robert George gave a presentation on PacketWay interoperability testing
- between Mississippi State University and Sanders. Successful testing of
- level A (EEP) fields was outlined. The implementations of MSU and LMMS
- not only were independent, but also use different computing models, as
- MSU maximizes the share of the host in implementing PktWay, whereas LMMS
- minimizes it, pushing tasks to the network interface processors.
-
- This test covered most of the EEP features, but not all. Among the
- features that were not tested yet are the endianness field, padding
- length, symbols, and priority.
-
- The interoperability test was very successful.
-
- Robert then presented a specific proposal for a compressed PktWay
- header. The header was 8 bytes in length as opposed to the 16 byte
- EEP header. It was requested that this header be sent to the PacketWay
- reflector to solicit comments from interested parties.
-
- Robert also mentioned that the working group plans to commence RRP
- interoperability testing by October.
-
- Since Robert already described the interoperability tests conducted with
- LMMS, Marc Fidler (of LMMS) did not deliver the presentation that he
- prepared of the same tests. Marc reiterated the need to clean up the
- PktWay documents.
-
- Shane Hebert gave a presentation dealing with the commercial need for
- PacketWay. He detailed MPI-Software-Technology's desire for PacketWay,
- along with the value of an IETF standardization for PacketWay.
-
- In summary, Danny reiterated the need to push the EEP document through
- editing, while, in the process, work on the RRP documents.
-
- All were encouraged to use the mailing list (the "PktWay-reflector").
- Danny thought that something was broken with the current reflector.
- He apologized for it, and promised to get it fixed soon.
