Assume CUSTb is a web server, and CUSTa is a T1 connected client. CUSTa sends a TCP SYN, accepts an ACK, and transmits 40 bytes of a URL. CUSTb responds to the SYN, accepts and ACK (3-way handshake) and transmits, in direct response to the URL request, 200KB of data back to the CUSTa. Now, NETb has a net deficit of packets to NETa. NETa says "pay up or else" and demands a settlement from NETb; a settlement which NETb cannot collect on, as NETb has no means of assessing CUSTa, which is the cause of the traffic so generated. NETb says "bite me", correctly perceiving that they should not allow arbitrary people to write blank checks on their accounts. NETa drops peering in response to the "bite me". NETa's customer drops their connectivity contract for a material breach of their agreement (deliberate interferance with their connectivity to NETb) and shops elsewhere. Who just lost by NETas activities here? That's what I thought. -- -- Karl Denninger ([email protected])| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly / All Lines K56Flex/DOV | NEW!
