摘要： Packets to be transmitted from a network device are buffered in queues in a first packet memory. In response to detecting congestion in a queue in the first packet memory, groups of multiple packets are transferred from the first packet memory to a second packet memory, the second packet memory configured to buffer a portion of traffic bandwidth supported by the network device. Prior to transmission of the packets among the one or more groups of multiple packets from the network device, packets among the one or more groups of multiple packets are transferred from the second packet memory back to the first packet memory. The packets transferred from the second packet memory back to the first packet memory are retrieved from the first packet memory and are forwarded to one or more network ports for transmission of the packets from the network device.

摘要： A switching system comprises a controlling switch and a plurality of port extenders. One of the port extenders includes: at least one upstream port; multiple downstream ports; and a forwarding engine. A forwarding database is populated with entries indicating associations between i) respective network addresses corresponding to devices coupled to downstream ports, and ii) respective local downstream ports. The forwarding database excludes entries corresponding to network addresses corresponding to devices coupled to the at least one upstream port. The forwarding engine is configured to: for a first packet received via one of the local downstream ports, and having a destination network address in the forwarding database, forward the first packet to a different local downstream port indicated by the forwarding database. For a second packet received via one of the local downstream ports, and having a destination network address not in the forwarding database, forward the second packet to the at least one upstream port.

摘要： Aspects of the disclosure provide a method for counting packets and bytes in a distributed packet-switched system. The method includes receiving a packet stream having at least one packet flow at a device of a packet-switched system having a plurality of distributed devices, statistically determining whether to update a designated device based on receipt of a packet belonging to the packet flow, and transmitting packet counting information to the designated device based on the statistical determination, where the designated device counts packets of the packet flow based on the packet counting information.

摘要： A network device includes one or more ports coupled to a network, and a time synchronization module. The time synchronization module processes (i) respective path information, and (ii) respective time synchronization information included in each of at least some of a plurality of time synchronization packets received from a master clock device over two or more different communication paths and via at least one of the one or more ports, wherein the respective path information indicates a respective communication path in the network via which the respective time synchronization packet was received. The time synchronization module determines a system time clock responsive to the processing of the path information and the time synchronization information included in the at least some of the plurality of time synchronization packets.

摘要： A memory supports a write or multiple read operations in any given clock cycle. In a first clock cycle, new content data is written to a particular content memory bank among a set of content memory banks. Also in the first clock cycle, current content data is read from corresponding locations in one or more other content memory banks among the set of content memory banks. New parity data is generated based on the new content data written to the particular content memory bank and the current content data read from the one or more other content memory banks. The new parity data is written to a cache memory associated with the one or more parity banks. In a second clock cycle subsequent to the first clock cycle, the new parity data is transferred from the cache memory to one of the one or more parity memory banks.
