Thank you to everyone who has offered different explanations.. Yes, all it take is one party pooper to spoil a good party... So now the question is (public or private) what is the best practices to protect the network ? :) Faisal Imtiaz Snappy Internet & Telecom ----- Original Message -----

(unless purely malicious or in error).I'm sure others will reply as well, but in case it helps someone googling in years to come... Let's look at ParasiteNet, a content heavy network with three BGP peerings: - Transit provider A via 100Mbps - Transit provider B via 100Mbps - Peer P via 1GBps (who also buys from provider B at 10G) If ParasiteNet needed to push more than 100Mbps to provider B, they might be tempted to route the traffic to peer P, even though peer P didn't advertise those routes. ParasiteNet gets a free ride if peer P doesn't notice what is going on (until they need more than 100Mbps inbound). I've been told of an occurance of this when a private network started peering with an edu network. Once the link was up, an absurd amount of traffic went across the link -- all destined for "the Internet" rather than the edu network. When the edu network shutdown the link, they were threatened with lawsuits...
