Abstract: The present disclosure relates to smart policy routing in a network. To this end, a network entity is configured to obtain policy information from a controller. The policy information can include one or more global intents and information about at least one SLA requirement for each of the plurality of flow groups. Furthermore, each global intent is indicative of one requirement of a network operator. The network entity further makes one or more routing decisions for the plurality of flow groups based on the policy information. In some examples, a controller is configured to provide policy information to the network entity.

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.
