Abstract: A network communication device including port control circuitry for controlling packet flow between the ports of the device, where the port control circuitry includes a port manager that directs packets between the ports and port bonding circuitry that bonds two or more ofthe ports into a bonded port set. For each packet to be sent via the bonded port set, the port bonding circuitry selects one of the bonded ports for transmitting the packet. More than one bonded port set may be defined in a given communication device, and each bonded port set may include from two ports up to all the ports of the device, as long as each port is included in only one bonded port set. One or more port bonding registers are provided to identify which ofthe plurality ofports are bonded in each bonded port set. In one embodiment, the bonded ports are selected on a packet by packet basis so as to achieve a relatively even distribution of packets sent by each bonded port. In an alternative embodiment bonded ports are assigned to packet source identifiers so as to achieve a relatively even distribution of source identifiers among the bonded ports. If bonded ports are assigned to particular source identifiers, then the traffic is preferably monitored and the assignments are periodically adjusted to achieve even distribution of packet flow on the bonded link. The bonded ports may have different bandwidths, in which case traffic is distributed on a proportionate basis.

Abstract: PROBLEM TO BE SOLVED: To enlarge available band width between two network communication devices without substantial change and without increasing the band width of an optionally given port by selecting a bonded port and transmitting a packet. SOLUTION: A network switch 102 includes a port control circuit connected to respective ports 104 in order to control traffic flows of the ports 104. The network switch 102 includes a port bonding circuit which is connected to the port control circuit or incorporated in it. In the same way, the network switch includes a port control circuit connected to respective ports 108 so as to control data traffic and a port bonding circuit which is connected to the port control circuit or incorporated in it. Then, the switch 102 selects one of the bond ports 140 and 142 in order to transmit a packet from a bond port switch 120.
