We experience a lot of types of attacks ("education/research network" = "easy hacker target"). With DDoS incidents, it seems we are more often an unknowing/unwilling participant than the target, partly due to owning big chunks of IP address space. We most frequently are the zombie/reflector participants in an attack that originates outside our network, to a target outside our network. As many as 8,000 hosts on our network are reflecting SYN floods in the current attacks.
I finally found a paper on this type of attack. http://grc.com/files/drdos.pdf and http://grc.com/dos/grcdos.htm describe the attack and a few possible defenses, though they are about as ineffective as most other DDoS defenses. Pete.
