Path protection of high priority traffic is provided between network nodes in a packet network carrying lower priority traffic in addition to the high priority traffic. First and second traffic paths are provided between the nodes, the high priority traffic being allocated to the first path and the lower priority traffic to the second path. In the event of a failure or degradation of the first path carrying the high priority traffic, this traffic is switched from the first path on to the second path and the lower priority traffic is switched to the first path.
