N2 - In an ATM network, calls are transmitted through several nodes. At this time, quality control over multiple nodes is considered to be better than quality control for each node independently. In view of such considerations, this paper proposed two control methods regarding discard (loss) quality and call level delay over nodes by carrying quality information in the call. In controlling delay quality, a call delayed at a node is given a higher priority in the next node to recover the delay. Since a cell can remain in one node for a long time, the buffer length of each node is lengthened. This leads to a decrease in the discarding rate. In addition, in discard quality control, the variations in the discard quality of each call can be minimized by performing discard of cells inside a buffer on the basis of the discard quality information of previous nodes when the buffer is full. The effect of these control methods is illustrated by simulation.
