    摘要: A switch is configured to block packets from being transmitted through designated ports. The switch has port bitmap generator configured to obtain a port bitmap and a table is configured to store a block mask indicating which port the packet should not be transmitted. A block mask lookup is configured to determine the block mask for the packet from the table, and a transmit port bitmap generator is configured to determine which ports the packet should be transmitted using the port bitmap and the block mask.

    摘要: A method for managing congestion in a stack of network switches includes the steps of receiving an incoming packet on a first port of a network switch for transmission to a destination port and determining if the destination port of the packet is a monitored port. Thereafter, the method determines a queue status of the destination port, if the destination port is determined to be a monitored port, and preschedules transmission of the incoming packet to the destination port if the destination port is determined to be a monitored port.

    摘要: A method of distributing data across a network having a plurality of equal-cost paths. Also, a device for distributing data over a network according to the method. The data, which is typically contained in data packets, may be distributed based on at least one attribute of each of the packets. The data may also be distributed according to a weighted distribution function that allows for unequal amounts of traffic to be distributed to each of the equal-cost paths.

    摘要: A network switch and a method thereof for network communications include a first data port interface and a second data port interface supporting a data port transmitting and receiving data at a first data rate and a second data rate, respectively. The switch has a CPU interface to communicate with a CPU and a memory management unit to communicate data from at least one of the first and second data port interfaces and a memory. The switch includes a communication channel communicating data and messaging information between the first and second data port interfaces and the memory management unit and lookup tables, including an address resolution lookup table and a VLAN table. The first or second data port interfaces determine an egress port for an incoming data packet from a search of the address resolution lookup table and the VLAN table using a VLAN ID from the incoming data packet.
