摘要： A network device includes memory having memory banks, and a packet processor module configured to receive bursts of packets and segment a received packet into a plurality of sections corresponding to the memory banks. The memory is configured to store a first section of a first received packet at a first one of the memory banks, continue storing remaining sections of the first received packet in remaining ones of the memory banks, and begin storing sections of a second received packet at a second one of the memory banks. The second one of the memory banks is offset from the first one of the memory banks by at least one of a number of memory banks that is less than a total number of memory banks required to store the first received packet, and a number of banks that is randomly selected for each of the packets.

摘要： An embodiment of the present invention reduces certain memory bandwidth requirements when sending a multicast message from a network device such as a router, bridge or switch. Separate output buffers are provided for different groups of egress ports, and incoming messages are written to some or all of the output buffers. A processing determination is made as to which egress ports will forward the message. Buffers associated with non-forwarding ports are released and the message is queued at the forwarding egress ports. When the message is forwarded, data is read from the output buffers associated with the forwarding egress ports.

摘要： Aspects of the disclosure can provide a network switch having reduced power consumption. The network switch can include a plurality of ports that are configured to receive and transmit network traffic. The plurality of ports can be configured in a power-on mode and a power-off mode. Further, at least a first port among the plurality of ports can be configured to remain in the power-on mode and to receive power control instructions. In addition, the network switch can include a power controller. The power controller can change the power modes of selected ports among the plurality of ports in response to the power control instructions received through the first port.
