| 摘要 |
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, specially a tagged communications network comprising links and nodes, said data flows including non-terminated data flows having specific characteristics. The network has different states (201-204) of functionality, wherein in a first state (201) when congestion or congestion anticipation in said specific characteristics substantially within the node of said network occurs, admission of new data flows having said specific characteristics is disabled, a number of flows are selected and a service level of the selected flows is changed. The arrangement mainly comprises a classifier arrangement, a load meter, first and second lists, first, second and third selectors a queue arrangement and scheduler.
