Bob,

The NSFNET fuzzbugs presently use an MTU of 576. With the latest fuzzware
the thugs can be set higher, while still using the buffer pool efficiently.
I chose 576 partly in defense of the buffer pool (tinygrams still sat
in a full packet buffer, but not any more) and partly to keep delays
small. In a rash moment, I've even thought about dynamic fragmentation
with preemption - a 20K monstergram getting sliced when a high-priority
tinygram arrives. For two dollars, I bet you don't remember where and
when that suggestion first came up (hint: it was at an overseas meeting).
The fuzz now have the hooks for schedule-to-deadline service. Thoughts
of stream-type service are prancing through my disheveled mind, but I
need to sweep out some other junk first.
