Abstract
A communication control apparatus includes an input and output unit responsive to reception of a packet, for generating a search request and a destination address of the packet to receive a resultant route data, and for transmitting the packet based on the resultant route data. A memory stores a route tree table having a tree structure of a plurality of nodes, each of which has a node data. A route searching circuit refers to the route tree table in response to the search request to determine a route data of a final node data as the resultant route data from the destination address, and outputs the resultant route to the input and output unit.
