Claim One:
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: at least one ring network primitive comprising a model of bi-directional traffic forwarding through at least two neighbour nodes interconnected in a ring topology; and at least one sub-ring network primitive comprising a model of bi-directional traffic forwarding through at least two neighbour nodes interconnected in a linear topology between first and second end-nodes, and between the first and second end-nodes via a virtual link mapped through at least one other network primitive.
