Abstract
The network switches and computer readable mediums of the present invention allocate port assignments based on load, that is, the amount of data being forwarded through each port in the group. The load balancing of the present invention is preferably dynamic, that is, packets from a given stream may be forwarded on different ports depending upon each port's current utilization. When a new port is selected to transmit a particular packet stream, it is done so that the packets cannot be forwarded out of order. This is preferably accomplished by ensuring passage of a period of time sufficient to allow all packets of a given stream to be forwarded by a port before a different port is allocated to transmit packets of the same stream. The invention may be used in a variety of different network environments and speeds, including 10Base-T, 100Base-T, and Gigabit Ethernet, and other network environments.
