CURRENT_MEETING_REPORT_ Reported by Jim Forster/cisco RREQ Minutes The Router Requirements Working Group split their work into two documents; Link Requirements and Router Requirements. The group further considered rewriting and consolodating the IP and ICMP specifications. There was consensus that this was a good thing, but there were doubts as to whether there was time or energy to do it. The router requirements document was edited on a comprehensive full pass. Issues discusses included: o Whether a router should support a public SNMP session. It was decided to pass this to the Interconnectivity Working Group. o The concept of minimum configuration was rejected for this document. The vendor must make sure that when a router comes on line, it does not begin a routing function, without being correctly configured. There needs to be a sanity check on certain parameters. o There was a discussion of routing preference order between routing protocols, such as IS-IS, and OSPF. The larger question was: Should we specify a routing entry preference? How should a router use a forwarding table and how should it be ordered? There was no consensus on this point. The only thing nearly everyone agreed on was that internal routes ought be preferred over external routes, and that RIP is unsatisfactory. Further, there must be a switch to determine which routing protocol is in charge. o Congestion control. Note that choosing to drop the last packet on the queue is the worst possible choice via three different experiments. The document will recommend that a router ought to have 2 * bandwidth delay product buffer space in every router along a path. We need to note that a lot of the problem of congestion is poor site engineering. Note that queue length ought not be allowed to rise too long. One needs to go into congestion avoidance if this is occurring. How one then throttles a host is still a problem. We note that there is no benefit to source quench.
