- MINUTES
-
- The PPP WG met on July 24, 25 and 26 at the IETF meeting at Stanford.
- Review of the latest draft of the specifications required discussion on the
- following areas:
-
-
- 1. An "Executive Summary" needs to be written for the beginning.
-
- 2. The PPP document should have less details of the HDLC protocol and have
- references to the appropriate documents on HDLC. The PPP document
- should include text of specifications that are unique to the PPP
- protocol application of HDLC.
-
- 3. All discussion of LAPB will be dropped from the document. The Enable
- LAPB option will also be removed.
-
- 4. There was again discussion of what protocol numbers to use, the
- ethernet numbers or new numbers. It was decided to let Jon Postel make
- the final decision with arguments presented for each case.
-
- 5. There was clarification of the wording in steps 3 and 4 of the
- description of the LCP sequence.
-
- 6. The Configure Request Request packet and the Character Generator
- Request/Reply packets were determined to be unnecessary and would be
- dropped.
-
- 7. A better description of Async Character Mapping is needed and how it
- relates to sync lines.
-
-
- Many other minor editing changes were suggested and will be incorporated in
- the next draft.
-
- The state diagram of the configuration exchange was examined in detail and
- the final form will be written up.
-
- There was a lengthy discussion on the best method for doing keepalives. The
- final conclusion was that a keep-alive request would be sent to the remote
- end containing the number of packets sent. The remote end would send a
-
- keep-alive reply containing the difference in the number of packets sent and
- the number of packets received. Policy on when to take the line down could
-
- be determined at each end independently based on the information provided by
- the keep-alive packets. A more detailed description of the mechanism will
- be written.
-
- There was discussion on what is the minimal implementation of PPP. The
- conclusion was: the minimum would be LCP configuration exchange with no
- options included. This would be followed by an IP configuration exchange
- with no options. The line would then be ready for IP traffic.
-
- Areas in need of further work are:
-
-
- o Stronger Authentication Protocols
-
- o Definition of encryption methods
-
- o Stronger IP address exchange methods
-
- o Definition of the use of other high level protocols
-
-
- The group plans to have a document with the agreed specifications finalized
- in two weeks followed with a video conference for verification of the text.
