Method and router for improved updating of a routing information base

摘要

Method for use in updating a routing information base of a node of a network, said routing information base comprising for each destination node of a number of destination nodes in said network a number of paths; wherein an update message with routing information is sent in said network from a first node to a peer of the first node, said first node having a first routing information base; wherein the update message comprises: a selected path for a first destination node of said number of destination nodes, said selected path comprising a next hop node adjacent the first node; at least one routing topology variable derived from the number of paths available for said first destination; said at least one routing topology variable being a measure for the risk on bottlenecks in the selected path.
