CONTROL OF OVERLOAD SITUATIONS IN FRAME RELAY NETWORK

摘要

PCT No. PCT/FI94/00534 Sec. 371 Date Sep. 24, 1996 Sec. 102(e) Date Sep. 24, 1996 PCT Filed Nov. 29, 1994 PCT Pub. No. WO95/15636 PCT Pub. Date Jun. 8, 1995The 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 (621 . . . 62n), (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.
