Abstract
A switched Ethernet controller (SEC) device and associated method that provides processor based intervention in the packet routing decision process is provided. The method of routing a multicast packet between a source port on a source device and a plurality of destination ports on a plurality of destination devices, utilizes a processor. The method includes the steps of the source device receiving the multicast packet via the source port, the source device sending the multicast packet to the processor, the processor examining the multicast packet, the processor determining the plurality of destination devices and corresponding the plurality of destination ports based on the results obtained during the step of examining, the processor transferring the multicast packet to the plurality of destination devices, and the plurality of destination devices sending the multicast packet to the plurality of destination ports.
