That is DAMNED impressive. I've never seen a router which can take a
Gigabit of traffic to its CPU and stay up. What kind of router was
this? You mentioned Juniper and Cisco before, but I know a cisco will
fall over long before a gigabit and a Juniper either does or drops
packets destined for the CPU (but keeps routing).
Perhaps it was rate limiting the # of packets which reached the CPU,
and the session stayed up because the "magic" packet was dropped in the
rate limiting?
