Patent

CA 2109787

Apparatus and methods used in a network for translating names into network addresses. Source nodes in the network receive names and have name caches for translating the names; destination nodes have have local name tables containing correspondences between names and the network addresses served by the destination node. There is further a name server accessible to the nodes which contains current correspondences between names and network addresses. A name is translated by first presenting it to the name cache in a source node; if there is no entry for the name in the cache, name cache maintenance code in the source node obtains information about the name from the name server; once there is an entry, the name is translated and a call set up message containing the name and the network address is sent to the destination node, which checks whether the name and network address are its local name table. If they are, the destination node returns a call complete message to the source node. Otherwise, it returns an unknown destination message to the source node. The name cache maintenance code responds to the unknown destination message by invalidating the cache entry and obtaining the correct information from the name server.
