Abstract:
A method for multicast packet transmission, executable in a software defined network having at least one input port, at least two output ports, and at least one network node. Switching rules are generated for transmitting at least one packet of a multicast group from an input port to an output port. For a given external traffic consumer, which is the first to request the multicast group, a shortest path from a given input port to a given output port, associated with the given external traffic consumer, is determined. For a subsequent external traffic consumer requesting the at least one multicast group, a shortest path from a network node closest to an output port of the subsequent external traffic consumer, where the switching rules for the multicast group are set, is determined.

Claim (Index 1):
A method for multicast packet transmission, the method executable in a software defined network, the software defined network having:\n at least one input port configured to receive packets from at least one external traffic source; at least two output ports configured to receive requests from at least one external traffic consumer; and at least one network node configured to generate switching rules; the method comprising:\n receiving, via the at least two output ports, a request to receive packets from at least one multicast group from at least one external traffic consumer; \n receiving, via the at least one input port, at least one packet of the at least one multicast group from an external traffic source; and \n generating, by the at least one network node, switching rules for transmitting packets of the at least one multicast group, the generating being executed such that:\n for a given one of the at least one external traffic consumer, the given one of the at least one external traffic consumer being the first to request the at least one multicast group, determining a shortest path from (i) a given one of the at least one input port associated with the given one of the at least one external traffic consumer to (ii) a given one of the at least one output port associated with the given one of the at least one external traffic consumer; \n for a subsequent external traffic consumer, requesting the at least one multicast group, determining a shortest path from a network node closest to the at least one output port of the subsequent external traffic consumer where the switching rules for the at least one multicast group are set; and \n \n causing the at least one packet of the at least one multicast group to be transmitted from the at least one input port to the at least one output port according to the switching rules.
