    摘要： Methods for routing control are disclosed. The methods may be performed, respectively, in network nodes and a controller node of a communication network, wherein the network nodes are operationally connectable to the controller node. A network node maintains a wireless communication link to another network node, wherein the link is subjectable to temporary performance degradations of a first type and a second type, temporary performance degradations of the first type having a first typical time duration which is shorter than a second typical time duration of temporary performance degradations of the second type. The method for the network node comprises detecting the link being subjected to a temporary performance degradation of the second type and transmitting (responsive to the detection) a report indicative of the temporary performance degradation to the controller node. The method for the controller node comprises receiving a plurality of reports from respective network nodes, wherein the reports are indicative of respective links being subjected to a temporary performance degradation of the second type, using the reports for a decision regarding temporary performance degradation of the second type, and using the decision regarding temporary performance degradation of the second type for routing control. Corresponding arrangements, network node, controller node, and computer program product are also disclosed.
