<p>The invention relates to a method for congestion management in an FR network, and to a node in an FR network. In the method, frames (39) are buffered both at the input and at the output boudary of the node, and a virtual channel associated with the frame (39) to be transferred is determined. In order to provide a new, reliable congestion management method allowing rapid responding and capable of offering even the user application behind the congestion service as well as congestion management mechanisms that reduce the level of service as little as possible, network services are classified into different classes (1, 2, 3) according to delay and frame throughput probability; and frames are forwarded in the nodes through service class specific buffers (44a...44d, 45a...45d, 64a...64d).</p> |
