Claim Text:
1. In a packet network having a mesh physical topology, a method of controlling traffic forwarding between a source node and a destination node of the packet network, the method comprising: controlling at least one physical node of the packet network to forward an end-to-end traffic flow between the source node and the destination node using a chain of interconnected network primitives extending between the source node and the destination node, the chain of interconnected network primitives including: wherein the controlling comprises detecting, by a physical node associated with a first network primitive in the chain of interconnected network primitives, a network failure affecting the end-to-end traffic flow between the source node and the destination node, and a Ring Protection Link (RPL) owner of the first network primitive restoring the end-to-end traffic flow by clearing a channel block of the first network primitive.
