基于高可靠性的重负载Ⅰ类双星网络性能评价的数学建模

摘要

充分考虑目前网络技术可靠性的大幅提升,忽略网络服务存在失败的情况,重新定义嵌入时点r系统状态的重负载条件,通过数学建模对双星网络的性能进行了再评价,求出了顾客转移概率Pij、顾客平均滞留时间等的算式,同时进行了模拟实验.与原有的性能评价相比,由于数学解析和结论简洁,本文的研究进展既有理论价值,更具有实用价值.%Taking Ml account of the high reliability of nowaday network technology,the instance of unsuccessful service can be ignored.This paper re-defined the system heavy load condition at embedding points,under which the performance of double-star is re-evaluated through the mathematical modeling. As the result,the customer transfer probability Pij and the mean detained time of the customers are given,and then the performance evaluation is done through simulation.Compared with previous performance evaluation, with the concise mathematical analysis and conclusion,this investigation has not only theoretical value,but also practical value.
