Analysis of a priority cell discarding method for ATM networks

One of the most important problems that must be solved in ATM networks is the priority cell discarding (PCD). A two priorities cell discarding method is suggested and analyzed under conditions of discrete time cell arrival. By introducing the operator, an iterative algorithm that can accelerate the speed of convergence when calculating the cell loss probability is suggested. The effectiveness of the PCD in ATM networks is proved by the numeric results.This work was supported in part by the National Key Laboratory of ISN.
