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.
