ABSTRACT:
Systems, apparatus, methods, and computer program products for multicast access control are provided to analyze incoming data based on a source zone and a destination zone of the incoming data. Appropriate access control rules are applied to incoming data based on the results of the analysis. Additional implementations of a multicast access control include using a proxy rendezvous point operable to function as a rendezvous point in place of a physical rendezvous point.
