DATA RELAY APPARATUS, ASSOCIATIVE MEMORY DEVICE, AND ASSOCIATIVE MEMORY DEVICE UTILIZATION INFORMATION SEARCH METHOD

摘要

It is possible to effectively input a search request command to an associative memory (CAM) device. When a packet is input, a search request (10) is generated by a network processor (1) and passed to the associative memory device (2). In the associative memory device (2), structure of the search request (10) is analyzed and a plurality of search conditions are generated. In the associative memory device (2), search is performed according to the search conditions and a memory address (21) corresponding to the search object information detected is output to a memory device (3). From the memory device (3), a search result candidate corresponding to the memory address (21) is passed as a search result (22) to the network processor (1).
