Abstract: A controller is configured to obtain traffic information of one or more tunnels in the network, where the traffic information of each tunnel is indicative of a protection type of the tunnel against failures, and provide configuration information to each network node that is a head-end node of a determined tunnel with a certain protection type according to the obtained traffic information of the determined tunnel, where the configuration information includes a bandwidth threshold and a load balancing configuration for the determined tunnel. A network node is configured to receive configuration information from the controller, and send the notification to the controller, if it is determined that the traffic of the tunnel is above the bandwidth threshold.

Abstract: The present disclosure relates to the field of transport networks, packet-based network systems, and load balancing in such network systems. More specifically, the load balancing is performed on a network cycle level. The present disclosure provides a network device for cycle-based load balancing, configured to obtain a load balancing policy comprising an input cycle identifier and an associated output identifier. The network device is further configured to obtain a network packet in an input cycle of the network device, determine an output of the network device based on the input cycle, the input cycle identifier, and the associated output identifier, and provide the network packet to the output of the network device.
