Abstract
A switch device for a network element includes a transfer system (110) for transferring data from ingress line interfaces of the network element to egress line interfaces of the network element in accordance with control information associated with the data. The transfer system includes a control section (111) configured to compare data traffic load to capacity available to the data traffic load at one of the egress line interfaces so as to generate a congestion indicator expressing whether a data flow (113) representing the data traffic load is a potential cause of congestion at the one of the egress line interfaces. The control section is further configured to direct a congestion control action to the data flow if the data flow is a potential cause of congestion. Thus, the congestion management related to the ingress and egress line interfaces can be carried out by the switch device.
