Abstract
In one embodiment, a method includes identifying a packet at an upstream node in communication with a source and in communication with a downstream node through equal cost multiple paths including first and second multi-access networks, the packet transmitted on the first multi-access network and associated with a multicast group, and transmitting from the upstream node a request to the downstream node to join the group on the second multi-access network, if the upstream node is already transmitting data to the group on the second multi-access network, or a bandwidth utilization at the first multi-access network exceeds a specified threshold. An apparatus is also disclosed.
