Techniques are presented herein that support application layer replication to optimally deliver multicast traffic over either the public Internet or a service provider network. The presented techniques encompass extensions to Border Gateway Protocol (BGP)-based signaling mechanisms that may be employed to notify network devices (such as endpoints) of the presence of an application-aware multicast capability. The presented techniques further encompass a replicator component that a controller may dynamically launch and program. Multicast traffic, that would normally travel along a conventional delivery path, may then take a unicast path to such a replicator at which point replication may be performed more efficiently within the network.
