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?
