摘要：
Systems and methods for determining multiple paths in a multi-domain network are provided. In some embodiments, a method for determining multiple paths in a network is provided. The method may include determining a first path between a source node and a destination node and determining a second path disjoint from the first path. In some embodiments, to determine the second path includes determining which ingress nodes are available in a domain that includes the destination node, where the available ingress nodes are not part of the first path, and implementing a disjoint path algorithm for each of the available ingress nodes. To determine the first path includes implementing forward path calculations.
