Abstract
An apparatus and method for defining content distribution paths in a content distribution network integrate unicast and multicast connections. Content engines in the content distributed network are organized into channels with a master content engine maintaining specific content. The content distribution network is further organized into a distribution hierarchy based on network topology and channel definitions, first by establishing unicast paths through the content distributed network and then by integrating multicast paths into the unicast hierarchy. The further organization of the content distribution network establishes distribution trees from the channel masters to the network edges.
