Selective multicasting of traffic flows in multiprotocol label switching virtual private networks

Abstract:

A first device may receive a traffic flow to be multicasted to at least two of a set of second devices. The first device may provide first messages to the set of second devices identifying the traffic flow. The first device may identify a set of interested second devices, of the set of second devices, based on respective second messages that are received from the set of interested second devices based on the first messages. The first device may determine whether a quantity of the set of interested second devices satisfies a threshold. The first device may selectively provide the traffic flow to the set of interested second devices, using a first type of multicast distribution tree or a second type of multicast distribution tree, based on whether the quantity satisfies the threshold.
