Convergent control manner and convergent control unit

摘要

PURPOSE: To perform the control for restoration from the congested state in the level of the lower-order level, where communication information is transferred, by detecting the fall. of a node system to the congested state to change a prescribed threshold value. ;CONSTITUTION: The service quality of cell traffic belonging to a connection 121 is set to a cell traffic control part 200 as the monitor parameter of cell traffic transferred on the connection 121. When a node system 112 falls to the congested state, EFCI (explicit forward congestion indication) is set to the header of a cell to be sent from the node system 112 to a terminal 101. When the cell traffic control part 200 detects whether EFCI is set or not to discriminate that the node system 112 falls to the congested state, the monitor parameter is so changed that the number of cells flowing to the node system 112 through the connection 121 is reduced.;COPYRIGHT: (C)1995,JPO
