Abstract
Embodiments for a method of controlling entry of packets into a broadcast network are provided. The method includes providing a plurality of edge devices communicatively disposed on an edge of the broadcast network. Reachability information is exchanged amongst the plurality of edge devices by translating Internet Protocol (IP) packets into ZOOM packets and including the reachability information in the ZOOM packets. A ZOOM packet has a data field that is a copy of a data field of the IP packet and a header that includes the reachability information. A first edge device of the plurality of edge devices maintains a table of forward destinations reachable via the broadcast network based on the reachability information exchanged. The first edge device discards IP packets from endpoint devices if the IP packets do not have a destination that is indicated as reachable in the table of forward destinations for that edge device.
