Abstract: In a multicast networking device having a plurality of output ports, a hierarchical packet scheduling tree is generated for a first port. The hierarchical packet scheduling tree is generated from a transmission queue for the first port. A sequential search of the hierarchical scheduling tree is performed to determine a packet pointer to a first packet in the transmission queue of the first port. Based on the packet pointer, packet data for the first packet is obtained and the first packet comprising the packet data is transmitted to a destination device via the first port.

Abstract: An improved method and apparatus for making forwarding decisions in a switching device. The invention reduces the flooding of frames to particular network segments connected to the switch. To insure a device sees a frame addressed to it, if a switch does not know what segment a device address is connected to for a unicast frame, the switch typically floods the frame to all segments in the broadcast domain. This invention allows segments to be identified as having a predefined maximum number of device addresses that will be associated with it. When that number of addresses is already in the forwarding table the switch will not flood unicast frames to that segment since no more devices should be connected to that segment.

Abstract: First data units corresponding to a first multicast group (MCG) and second data units corresponding to a second MCG are stored in a first queue of a network switching device. At least one first data unit retrieved from the first queue and at least one second data unit retrieved from the first queue are aggregated into a first frame. The first frame is transmitted by the network switching device to a superset MCG that includes at least the first MCG and the second MCG. Only third data units corresponding to a third MCG are stored in a second queue of the network switching device. Third data units retrieved from the second queue are transmitted by the network switching device to the third MCG.
