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.

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: 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 device for controlling network routing configurations is configured to obtain a predicted traffic matrix and a plurality of traffic matrices, and to determine, from a plurality of clusters, arranged in a hierarchical structure over the predicted traffic matrix and the plurality of traffic matrices, a first cluster allocated to a lower hierarchy level that contains the predicted traffic matrix. Each of the clusters is associated with a routing configuration, and the plurality of clusters are allocated to at least two different hierarchy levels. The device selects, from the plurality of clusters, a second cluster allocated to a higher hierarchy level that includes at least the first cluster and a third cluster allocated to the lower hierarchy level that contains a current traffic matrix, determine a second routing configuration associated with the second cluster; and activate the second routing configuration as a network routing configuration.

Abstract: A method, an apparatus and a non-transitory computer-readable storage medium for determining multiple disjoint constrained paths in a communications network are disclosed. The method includes selecting upper bounds QoS metrics for each path in a disjoint combination of paths having two or more disjoint paths between a source node and a destination node; determining a minimum-cost disjoint path combination, and a minimum-QoS metric disjoint path combination; computing a maximum QoS metric by summing the QoS metrics of each minimum-cost path in the minimum-cost disjoint path combination, and computing a minimum QoS metric by summing the QoS metrics of each minimum-QoS metric path in the minimum-QoS metric disjoint path combination.
