ABSTRACT:
A bridge circuit is provided for connecting at least two networks. The addresses of sending and receiving stations in a message received from a network are subjected to cyclic redundancy checking (CRC), and the results of CRC of the source are used as the memory addresses for storing the address information of the sending stations in the network. When a message is received, the message receiving operation is continued or stoped in accordance with the content of the memory read from the results of the CRC of the destination address. Using CRC codes frees a microprocesor in the bridge circuit from processing the storing, retrieval, comparison and judgement of the addresses of the sending and receiving stations, thereby increasing the message transferring speed between the networks.
