Does anyone know, either on the east coast US, London, Stockholm, Copenhagen, Amsterdam or Helsinki transit providers which would allow edge/handoff interface control to different traffic classes using BGP communities? (for example to announce DDoS destinations

Null communities suporting organizations: GBLX, UUNET, NLAYER, et al Others who can also do null routing over bgp community, please come forward. One of my customers may be interested in doing business w/ you ;-)

and/or sources with different community which would drop the precedence of those packets to a lower level and thus de-prioritize them and allow legitimate traffic to have better performance)

I have not seen any QoS policy propagation over BGP (qppb i think is what they call it?) stuff in provider environment yet.. I dunno if qppb is even the right thing for this, but I think it is. But then again, considering most providers don't even support null community, this is like asking too much ;-) And qppb would be something new and it would put more strain on router as it has to rate limit stuff now.. -hc -- Haesu C.
