We see similiar problems, functional capability for interactive
applications like telnet is MUCH better through the CIX than through
the NSFNet. When "SaltLakeCity" has its normal problems (we've seen
about a dozen in January, and we're not looking really) then it goes
through the roof.
Leveraging off another posting elsewhere, I was wondering how hard it
would be for cisco to change their architecture to have multiple routing
tables and slightly modify their protocol prioritization scheme so that
telnet/rlogin is not just prioritized but goes out a different path
(specifically the CIX path).
