COMPUTING PATH INFORMATION TO A DESTINATION NODE IN A DATA COMMUNICATION NETWORK |
摘要 |
Approaches for computing path information to a destination node in a data communications network are described. A data communications network comprises as components nodes and links therebetween and comprising a core subdomain of components and a plurality of non-core subdomains of components and having a common identifier for each non-core subdomain. An apparatus comprises first logic which when executed is operable to receive reachability information for a destination node and an associated identifier; and second logic which when executed is operable to perform a computation of path information for a path in the network to a destination node dependent on a particular identifier of a subdomain associated with the destination node, and to forward data for the destination over the path according to the path information.
