摘要： An arrangement for scheduling scans of internal network nodes for reachability events by a border node of a network domain, schedules the scans according to the rate at which reachability notifications are received by the node. As the rate at which notifications are received increases, the interval between scans also increases. Conversely, as the rate of notifications decreases, the interval also decreases.

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.
