摘要
A method in a network utilizing a distributed connection-oriented control plane includes signaling a first path for a first connection from a first source node; storing call information for the first connection at any intermediate nodes in the first path; signaling a second path for a second connection from a second source node; checking at any intermediate nodes in the second path if there is absolute route diversity between the first connection and the second connection responsive to a requirement therein; and responsive to detecting a diversity violation at an intermediate node of the any intermediate nodes in the second path, signaling a crankback to the second source node with the call information for the first connection included therein; and recomputing the second path exclusive of the first path based on the call information responsive to receiving the crankback. A network and node are also described.
