Abstract: A method for operating a network having a plurality of terminals and a plurality of switches connected to one another via data lines has the first step of transmitting a multicast MMRP data packet from a data source via at least one of the switches and one of the data lines to a predetermined terminal intended to receive the multicast data packet. Then one port of a switch to which is connected another terminal that is not MMRP-capable is fed the multicast address as a static entry of the terminal connected to the one port. The multicast address is then transmitted to the at least one switch connected thereto.

Abstract: Described embodiments provide a method of processing packets of a network processor. One or more tasks are generated corresponding to received packets associated with one or more data flows. A traffic manager receives a task corresponding to a data flow, the task provided by a processing module of the network processor. The traffic manager determines whether the received task corresponds to a unicast data flow or a multicast data flow. If the received task corresponds to a multicast data flow, the traffic manager determines, based on identifiers corresponding to the task, an address of launch data stored in launch data tables in a shared memory, and reads the launch data. Based on the identifiers and the read launch data, two or more output tasks are generated corresponding to the multicast data flow, and the two or more output tasks are added at the tail end of a scheduling queue.
