Abstract: Disabling mutually recursive routes is disclosed. An event that results in a routing table update is received. A next hop table is updated to reflect the event. It is determined whether the event is associated with an exterior protocol route. The next hop table is used to perform a recursion check if it is determined that the event is associated with an exterior protocol route.

Abstract: A technique is disclosed for detecting a memory leak. A request to allocate or deallocate memory is received. In a memory leak table that is bounded in size, an entry that is associated with a call path with which the request is associated is accessed. The entry in the memory leak table is updated.

Abstract: 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.
