Selection technique for preventing a source port from becoming a destination port in a multi-port bridge for a local area network

摘要: A selection technique for filtering packets in a multi-port bridge local area network, thus, preventing source port packet from becoming destination the packet. The includes memory storing and plurality of ports. Each receive buffer, transmit buffer pointer buffer. is received by port. As still being received, look-up table utilized to determine which one or ones ports are appropriate assigned respective signal lines communication bus. product utilizing tables referred as bit-map logic level each line wherein indicative whether corresponding placed on bus monitored If designated bit-map, this indicates that nodes same segment network (intra-segment communication). From bit map, also determines any other no destination, discards incoming packet, thus If, however, continues receiving transmission such
