Abstract:
A capability is provided for supporting fault-resilient propagation of traffic in networks using redundant multicast trees (RMTs). Fault-resilient propagation of traffic from a first node to a second node is supported using one or both of a pair of RMTs rooted at the first node and a pair of RMTs rooted at the second node. The pair of RMTs rooted at the first node includes a pair of node-disjoint paths from the first node to the second node. The pair of RMTs rooted at the second node includes a pair of node-disjoint paths from the second node to the first node. The first node propagates multicast traffic toward the second node using at least one of the RMTs in the pair of RMTs rooted at the first node. The first node propagates unicast traffic toward the second node using at least one of: at least one of the RMTs in the pair of RMTs rooted at the first node, or at least one of the RMTs in the pair of RMTs rooted at the second node.
