摘要:
A method and a system for congestion management in a frame relay network, which includes a) buffering of data at the input boundary of a subscriber node to virtual-channel-specific buffers, b) transmitting congestion notifications in a backward direction from the network nodes to the subscriber node of the moment, and c) controlling the amount of traffic supplied towards the network from the subscriber node buffer.
摘要:
The invention relates to a method for congestion management in an FR network. The method comprises determining the virtual channel associated with a frame to be transmitted when it is received from a subscriber connection at a subscriber node. In order for the load in the network to be reduced, (a) data is buffered at the input boundary of the subscriber node to virtual-channel-specific buffers (62.sub.1 . . . 62.sub.n), (b) the fill rate of said buffers is monitored continuously, and (c) when a frame is received in a virtual-channel-specific buffer which is full, substantially all the contents of the buffer are discarded.
