推导出系统性能重要参数-信元丢失率、平均信元延迟、吞吐率等的计算公式

并通过数值分析对系统性能进行了考察和评价.此外

通过与仿真结果的比较验证了数字解析的正确性和合理性.

Abstract

In this paper

the priority control method

called "Hot-Spot Push Out" (HSPO)

is used for analyzing the performance of shared buffer ATM switches under a non-uniform traffic.The system performance model is theoretically analyzed and the important calculating formulas of the system performance parameters

such as "cell loss ratio" 、 "mean cell delay" 、 "throughput"

etc

are derived based on queueing theory.The system performance is examined by numerical analysis.In addition

The results compared with simulation show that the theoretical analysis is correct and reasonable.
