Abstract
Systems and methods according to these exemplary embodiments provide for methods and systems for interworking between an Internet Group Management Protocol (IGMP) and a MAC address Multiple Registration Protocol (MMRP). For example, an IGMP join or leave message which is received at node is translated into an equivalent MMRP message for forwarding into an MMRP portion of a network.
Claims16
A method for interworking between an Internet Group Management Protocol (IGMP) and a MAC address Multiple Registration Protocol (MMRP) comprising:
- receiving an IGMP message related to members of a multicast group at a node;
- translating said IGMP message into an MMRP message, wherein said step of translating further comprises:
- determining an originating virtual local area network (VLAN) associated with said IGMP message;
- transmitting said MMRP message from said node;
- and
- wherein multicast traffic is directed to the members of the multicast group.
A node which provides for interworking between an Internet Group Management Protocol (IGMP) and a MAC address Multiple Registration Protocol (MMRP) in a communications network, said node comprising:
- a communications interface which receives an IGMP message at said node;
- and
- a processor which translates said IGMP message into an MMRP message, and transmits said MMRP message from said node, wherein said processor determines an originating virtual local area network (VLAN) associated with said IGMP message.
