  • Abstract In ATM (asynchronous transfer mode) networks, rate-based regulation-scheduling (R&S) mechanisms guarantee certain quality of service (QoS) with controlling the rate of a tagged connection serviced by the switches. The R&S mechanisms, which consider only the issues of one tagged connection itself but the situation of the scheduling queue, can behave hand-over well. However, there may be many connections hand over in identical condition and compete for the position in the scheduler queue. It makes the transmission to be distorted greatly from the hand-over. There is already a scheme, dynamic R&S, to smooth rate jitter with counting the hand-over of other connections. Dynamic R&S doesn't count the idle slots, which also make the interval between two consecutive tagged cells, and results in unnecessary misses. The new scheme proposed considers the system time and scheduler queue's length. It has less difference between transmission intervals and the premised one of a tagged connection, so that is better in rate-jitter control. This mechanism has O(1) time-complexity, so conforms to the demand of high-speed ATM networks.
