本文对非均匀业务下共享存储器ATM交换机采用热点推出(HSPO)优先级控制策略方案建立了系统模型.文章通过排队理论对系统模型进行了数学解析
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.
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.
