has something called Source Path Isolation Engine (SPIE). ThereThis would be cool to see a design/whitepaper for.. Kelly?
The long version of the SPIE paper is at: http://nms.lcs.mit.edu/~snoeren/papers/spie-ton.html The two second summary that I'll probably botch: SPIE keeps a (very tiny) hash of each packet that the router sees. If you get an attack packet, you can hand it to the router and ask "From where did this come?" And then do so to the next router, and so on. The beauty of the scheme is that you can use it to trace single-packet DoS or security attacks as well as flooding attacks. The downside is that it's hardware. -Dave -- work: dga () lcs mit edu me: dga () pobox com MIT Laboratory for Computer Science http://www.angio.net/ I do not accept unsolicited commercial email.
