ABSTRACT:
A routing device includes a memory for storing routing entries in a routing table and a cache memory for storing some of routing entries present in the memory together with a mask length of a destination address as a cache entry. A high-speed retrieval section retrieves the cache entry corresponding to the destination address by referencing the cache memory based on the destination address of an input packet. An ordinary retrieval section retrieves the routing entry corresponding to the destination address by referencing the memory. A processing section writes the cache entry into the cache memory based on the routing entry retrieved by the ordinary retrieval section. The router device enables routing without using a routing entry that should not be used in the routing originally even when part of the routing table is cached.
