- MINUTES
-
- This was the third meeting of the MTU Discovery Working Group.
-
- Jeff Mogul started with a review of where we had been in the past 5
- months, including all the failed approaches. He then presented the
- current proposal, originated by Steve Deering. Summary: send all
- packets with the DF bit set. Routers that cannot forward these packets
- return a slightly modified ICMP message that indicates the appropriate
- MTU. (Current routers return ``0'' in the field meant for this purpose.)
- The sending host revises its estimate of the Path MTU, and retransmits
- the dropped datagram.
-
- There was no objection to the basic design. Some discussion ensued
- concerning details of the implementation and the relation between Path
- MTU discovery and transport protocol actions.
-
- This design solves many problems with the previous designs, especially
- because it is compatible with existing hosts and routers, and is quite
- simple to implement.
-
- ACTION ITEMS
-
-
- 1. Jeff Mogul and Steve Deering will change some details in the
- current draft and submit it as an Internet Draft.
- 2. The Router Requirements working group should be notified that we no
- longer care how fragmentation is done, since we don't rely on the
- sizes of fragments. We will also recommend that support for MTU
- Discovery be made a requirement.
-
-
- SCHEDULE
-
- We expect never to meet again. Progress towards standardization will go
- as fast as possible, unless serious objections are raised.
