Abstract
Systems and methods to distribute media content are provided. A particular method includes receiving first link weighting factors and second link weighting factors at a router of a node of a multicast network and determining a primary path to a next hop node based on the first link weighting factors. Additionally, the method includes determining a backup path from a router of the primary path to the next hop node based on the second link weighting factors. The backup path does not overlap any primary path between two nodes of the network. Further, the method includes receiving a data packet from a parent node and routing a copy of the data packet from the router to the next hop node via the backup path, when a network link related to the router has failed. The method also includes routing data packets via a re-configured multicast tree that excludes the failed link.
