Edge-router scaling for BGP peering with virtual private routed networks (VPRN)

摘要

An edge router in a packet network has a processor resource for processing events, at least one scheduler managing all events for processing by the processor resource, at least one ready list, and individual event pipelines dedicated to individual ones of BGP peers. Events received for processing are posted in their associated event pipelines according to the source of the events, pipelines having events to be processed insert a flag in the ready list and the scheduler repetitively scans the ready list sequentially, and releases events to the processor resource with preset limitation per pipeline.
