Abstract

The invention provides a MAC address matching processing device and method. The device includes: a cache module for buffering messages to be matched; a matching control module including a detection unit, a matching unit, a state unit and a control unit connected in sequence: the matching unit includes a plurality of comparators respectively connected to the detection unit, The status unit includes a plurality of status registers, and each status register corresponds to each comparator; the control unit is connected to the buffer module; the detection unit is used to obtain the destination MAC address of the message to be matched, and send the destination MAC address to a comparator In the device; multiple comparators are used to store the destination MAC address respectively, and perform MAC matching on the destination MAC address stored separately according to the local MAC address table; multiple status registers are used to respectively The corresponding matching status information is set; the control unit is used to process the buffered messages to be matched according to the matching status information.

Description

technical field [0001] The present invention relates to a data communication technology, in particular to a media access control (MediaAccess Control, abbreviated: MAC) address matching processing device and method. Background technique [0002] During the transmission of Ethernet data packets, the routing device working on the Ethernet filters the received packets by setting the local MAC address table, and matches the MAC addresses of the received packets to Messages are filtered out to avoid receiving redundant messages to increase the processing burden of the system. [0003] Usually, according to the destination MAC address of the received message, the routing device scans the entire table in the saved MAC address table to match the MAC address. If there is a matching address that is the same as the destination MAC address, the MAC address is matched successfully. If the entire MAC address table is scanned and no matching address is found that is the same as the destin...
