  • Method for pruning a multicast branch, protocol independent multicast router, and layer-2 exchange
    Patent number: 9497034
    Abstract: According to an example, a multicast source may be connected to a first hop Protocol Independent Multicast (PIM) router via one or multiple layer-2 switches that has PIM functions. A first hop PIM router may receive a multicast flow initiated by the multicast source, send a PIM prune message via a port from which the multicast flow is received in response to a determination that the multicast flow is not to be received, or the first hop PIM router may receive a PIM prune message for a multicast flow from a downstream PIM router or a multicast group leave message for a multicast flow from a client connected to the first hop PIM router and delete a port via which the PIM prune message.
