Effective priority control scheme according to cell loss probability in ATM

This paper present a new priority control mechanism which is to balance the cell loss rate by measuring, in real time, the number of discarded cells in the queuing system with a different loss priority for each class of service such that each class of service meets its cell loss rate requirements. To reduce the delay rates we modified the existing cell scheduling scheme. Throughout the computer simulation, the existing schemes and proposed scheme is compared with respect to cell loss rate and average delay time. The proposed scheme has improved performance more than the other schemes with respect to cell loss rate and average delay time.
