    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 receiving, at a first machine, a multicast data packet from an ingress provider edge router of the communication network, the multicast data packet associated with a multicast route, and transmitting a first replication of the multicast data packet from the first machine to a second machine via a first unicast path. The first replication of the multicast data packet includes a first label provided by the second machine to identify the multicast route in the second machine. Example methods further include receiving the first replication of the multicast data packet at the second machine via the first unicast path, and replicating the multicast data packet from the second machine to an egress provider edge router of the communication network.

    Abstract: A method, apparatus and computer-readable storage medium distribute a non-live content stream in a network. An initial meta-file is transmitted in response to a request for the content, which identifies a division of the content stream into blocks, and available sources for delivery of the blocks. The initial meta-file can identify a first multicast and a second multicast server, assigning a first and second portion of the blocks for delivery using the first and second multicast source server, respectively. The first and second portions are transmitted using the first and second multicast source servers, respectively. The first and second portions correspond to distinct non-overlapping portions of the non-live content stream. The initial meta-file can also identify a unicast source server, assigning a third portion of the blocks for delivery using the unicast source server, the third potion being transmitted by the unicast source server.

    Abstract: Methods, apparatus, and articles of manufacture to provide a multicast virtual private network (MVPN) are disclosed. Example methods to transmit multicast data in a network disclosed herein include monitoring, with a first network node, a multicast data flow to determine a characteristic for triggering a switch from a first logical topology for the multicast data flow to a second logical topology for the multicast data flow. Disclosed example methods also include, after the switch to the second logical topology, accessing a multicast data packet associated with a first multicast route generated for the multicast data flow from a second network node, and transmitting a first replication of the multicast data packet to a third network node via a unicast path, the first replication of the multicast data packet to include a first label provided by the third network node to identify the first multicast route.
