The present invention refers to a method and arrangement for controlling congestion of a network node capacity shares used by a set of data flows in a communications network, especially a tagged communications network having links and nodes. The data flows include non-terminated data flows having specific characteristics. The network has different states of functionality, wherein in a first state when congestion or congestion anticipation in the specific characteristics substantially within the node of the network occurs, admission of new data flows having the specific characteristics is disabled, a number of flows are selected and a service level of the selected flows is changed. The arrangement mainly includes a classifier arrangement, a load meter, first and second lists, first, second and third selectors a queue arrangement and scheduler.
