Abstract 1. Field of the Invention Data structures, a method, and an associated transmission system for multicast transmission on network processors in order both to minimize multicast transmission memory requirements and to account for port performance discrepancies. Frame data for multicast transmission on a network processor is read into buffers to which are associated various control structures and a reference frame. The reference frame and the associated control structures permit multicast targets to be serviced without creating multiple copies of the frame. Furthermore this same reference frame and control structures allow buffers allocated for each multicast target to be returned to the free buffer queue without waiting until all multicast transmissions are complete.
