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.
