Is anyone else having trouble maintaining their peer relationships
with the core? We are seeing excessive problems with high packet
loss and eventually being dropped.
Greg, There is an arpanet/internet 'event' happening which shows up as long
queues in both directions between the PSNs and the core gateways. Also, the
psn-gateway connection is broken frequently which causes all the queued
packets to be discarded. Does your gateway on the arpanet get clogged also?
One change that may have affected the system is the introduction of fragmented
NR messages (EGP updates), which now take 2 arpanet messages each longer than
128 bytes; the fragments are about 1000 bytes and 200 bytes, and growing.
Some facets of the problem that are being explored are the differences between
the arpanet PSN software release 7 and the old release 6, speeding up the
processors in the core systems (upgrade lsi-11/23 to /73), and checking the
timing on the EGP implementations.
