Abstract
Methods and apparatus for network multicasting using hierarchical replication are disclosed. An example method disclosed herein to send multicast data associated with a source to a plurality of receivers in a network comprises replicating the multicast data received at a first network node, the multicast data received via a first unicast path, the first network node being associated with a first hierarchical level of a replication hierarchy, sending copies of the multicast data to a plurality of network nodes associated with a second hierarchical level of the replication hierarchy via second unicast paths, and replicating a copy of the multicast data received via one of the second unicast paths at a second network node to send the multicast data via a third unicast path for receipt by a receiver in the plurality of receivers, the second network node being in the plurality of network nodes associated with the second hierarchical level.
