摘要： In one embodiment, a load-balancing algorithm ensures that both network nodes at endpoints of a group of physical links aggregated into a logical channel are using the same load-sharing algorithm and also ensures that the load-sharing algorithm is normalized so that the same flow traverses the same physical link in both directions.

摘要： Only one point to multipoint virtual circuit (p2mp VC) is used within a router to handle all of the sources for a particular multicast group when other particulars of the multicast group are identical within that router. The router receiving a multicast packet for a particular multicast group identifies the source and the group number by reading fields of the incoming packet, identifies the input port of the router, and identifies the output port list. The input port of the router, the group number G, and the output port list are used by the router in establishing and identifying a point to multipoint VC within the router. The invention identifies all packets arriving at that particular input port, having the same multicast group number G, and having the same output port list, and transfers them to the identified VC. The VC is associated in the routing table with the output list of ports from which copies of the multicast packet are transmitted. Accordingly, only one VC is needed to transfer packets arising from any source of the multicast group so long as the multicast packets arrive on the same port of the router and have the same output port list.

摘要： A method for providing BGP route updates in an MPLS network is disclosed. The route update is performed at a router having a forwarding information table containing BGP routes and an internal label, and an adjacency table containing BGP/VPN labels and said internal label. The internal label corresponds to at least one IGP route and has an adjacency associated therewith. The method includes updating the adjacency associated with the internal label following an IGP route change.
