Abstract: An edge device is for a distributed traffic engineering system with quality of service control of a plurality of flow groups routed over a set of overlay links. The edge device is configured to receive one or more service-level agreement requirements for the plurality of flow groups from a network controller, receive first control information from one or more other edge devices in the distributed traffic engineering system, obtain monitoring information for the plurality of flow groups and the set of overlay links, and adjust a plurality of queuing parameters for the plurality of flow groups based on at least one of the first control information, the monitoring information, or the one or more SLA requirements.

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.
