A DATA SWITCH, AND COMMUNICATION SYSTEM USING THE DATA SWITCH

摘要

A data switch includes a first processor (31) for routing data packets including a MAC address, using a MAC address table stored in a writable memory (35). The switch further includes a second processor (33) for routing data packets including an IP address using an IP address look-up table (15) stored in the writable memory (35). The writable memory (35) consists of a single memory fabric which is allocated between the MAC address table and the look-up table by a memory control unit (39) according to a setting stored in a non-erasable memory unit (37).
