摘要： The present invention provides a method of controlling data flow within a network device. The method includes the steps of snooping a data packet before the data packet is stored in a memory buffer of the network device to determine a packet size, aggregating the packet size to generate a total number of data packets within a burst if the packet size exceeds a predetermined packet size. The method also includes the steps of lowering a threshold of the memory buffer to a reset threshold if the total number of data packets exceeds a predetermined number of consecutive data packets and activating a pause frame based upon the reset threshold to temporarily suspend transmission of incoming data packets to the network device.

摘要： An Asynchronous Transfer Mode ATM receiver is disclosed. The ATM receiver comprises an input that receives an ATM cell. A first-in first-out (FIFO) is coupled to the input. The FIFO stores the ATM cell received from the input. A header error correction (HEC) checking circuit is coupled to the input. The HEC checking circuit starts to check a header in the ATM cell for an error at substantially the same time when the ATM cell is being stored in the FIFO.

摘要： A network switch that includes an address resolution table and a VLAN table. The address resolution table comprises a VLAN identifier (ARL VID) in less significant bits, a MAC address, and an action code, wherein each VLAN identifier in the address resolution table is unique. The VLAN table is used for storing information related to frame forwarding. The VLAN table includes a VLAN identifier (VLAN VID) in more significant bits, a forward map and an un-tag map. The ARL VID is used to access an associated entry in the VLAN table.
