Abstract:
1. A method comprising: receiving in a first network interface of a router a first request for a first type of multicast traffic in a first multicast routing protocol, storing in the router for the first network interface and the first type of multicast traffic a second type of multicast traffic, transmitting from the router using a second multicast routing protocol requests for the first and second types of multicast traffic, receiving in the router the first and second types of multicast traffic comprising first and second IP packets, respectively, modifying in the router one or both of the IP source address and the IP multicast destination address of some or all of the second IP packets so that the IP source address and the IP multicast destination address of some or all of the second IP packets are the same as the first IP packets of the first type of multicast traffic and transmitting the first IP packets and the modified second IP packets via the first network interface, wherein the router transmits in a first time interval a portion of the first IP packets via the first network interface, transmits in a second time interval following the first time interval all or a portion of the modified second IP packets via the first network interface, and transmits in a third time interval following the second time interval some or all of the remaining portion of the first IP packets via the first network interface.
