QoS and fault isolation in BGP traffic, address families and routing topologies

摘要

A method is disclosed for routing BGP traffic. In one embodiment, according to the method, an association is formed between a first process and a second process. The first process includes a first BGP process on a first peer and the second process includes a second BGP process on a second peer. The association is formed using a reliable datagram-oriented IP transport protocol. Traffic sent from the first BGP process is segregated into a control traffic type and an update traffic type and any more finer classifications that can further classify BGP traffic. The traffic from the first BGP process is sent to the second BGP process in accordance with a priority allocation assigned to the traffic types based on the association.
