Re: Update identification and length

I don't know if I'm an opponent of Routing Over TCP, but I seem to
remember Dennis Ferguson mumbling something to the effect that the
VJ TCPs back off so aggressively in response to congestion that you
get some undesirable delay or timeout effects if backoff kicks in,
so you either don't want to use links as slow as 56kb or should use
priority mechanisms to protect the routing traffic.  This was something
he observed somewhere real, but I don't recall specifics.

Personally I think priority to protect the routing traffic is a rather
reasonable idea, and I also have this attitude that TCP backoffs per
accepted VJ religion may be more aggressive than is good for us, but
this kind of statement alarms the converts to binary exponential backoff.
However I note that the theory of these things does not say that you have
to have K**N with K=2 to recover, but rather K>1.  But I digress...
