I always assumed that taking in more traffic was a bad thing. I've heard about one sided peering agreements where one side is sending more traffic than the other needs them to transport. Am I missing something? Would this cause a shift in their favor allowing them to offload more customer traffic to their peers without complaint? 2011/12/15 Jeff Wheeler <jsw () inconcepts biz>

While not quite as obvious, some large transit ASes, like Level3, reset the origin to I (best) sometime between when they learn it and when they announce it to their customers and peers. This similarly causes them to suck in a bit more traffic than they might otherwise. -- Jeff S Wheeler <jsw () inconcepts biz> Sr Network Operator / Innovative Network Concepts
