METHOD AND APPARATUS FOR HANDLING MULTICAST TRAFFIC

摘要

Aspects of the disclosure provide method and apparatus for managing multicast traffic in a domain, such as a G.hn domain. A method includes storing, at a first node of a domain, a plurality of next nodes for transmitting messages in the domain, forwarding, from the first node to the plurality of next nodes, a probe message transmitted from a second node in response to a request from a third node to join a group to receive a multicast flow that enters the domain from the second node, and storing, at the first node, a list of nodes in association with the multicast flow. The list of nodes is determined at least in part based on a path through which the probe message is transmitted from the second node to the third node.
