The abstract of the patent published by the U.S. Patent and Trademark Office states: "In one embodiment, a method includes receiving a join message from a receiver at a receiver edge router, the join message identifying a source and a group, and creating at least two forwarding trees for transmitting multicast data streams comprising duplicate data to the receiver edge router. The forwarding trees include a root at a source edge router in communication with the source, and different network paths. The method further includes receiving a packet from one of the forwarding trees and processing the received packet to determine if the packet is a duplicate of another packet received at the receiver edge router. If the packet is a duplicate packet, it is discarded. If the packet is not a duplicate, it is forwarded to the receiver. An apparatus is also disclosed." The patent application was filed on Aug. 28, 2009 (12/584,008).
