A multi-protocol label switching network or domain (1), and method of operating the same. Label switching control paths are established for forwarding control packets between routers (E1-E4, C1-C6) according to control labels assigned to the control packets by a label assignment server (2). Control labels are assigned by assigning a respective unique control label to respective directional pairs of edge routers, each directional pair comprising a combination of an edge router pair and a direction between the edge routers of the pair. Traffic data paths are also established for forwarding traffic data packets between the routers according to traffic data labels assigned to the traffic data packets. The traffic data labels are distinct from the control labels, and the traffic data paths are different from the control paths.
