Abstract:
Methods, apparatus, and articles of manufacture to provide a multicast virtual private network (MVPN) are disclosed. An example method to transmit multicast data over a communication network includes: determining an upstream hop of a multicast transmission based on a received hierarchical ingress replication route; storing a downstream hop and the upstream hop of the multicast transmission in a multicast routing table; monitoring the multicast transmission occurring via an area border router; in response to detecting at least one of a) a threshold fan-out of the multicast transmission or b) a threshold data rate from a source of the multicast transmission, converting a logical topology of the multicast transmission; and in response to receiving a multicast data packet of the multicast transmission, replicating the multicast data packet with the processor based on the downstream hop.
