对网络系统中的时延等性能指标问题,利用随机网络演算对单节点服务器建立ON/OFF到达模型和常速率服务器模型,建立了单节点服务器的时延分析框架,求解得到时延的边界,并通过NS2仿真工具进行实验分析验证了框架的有效性。该方法得到的时延的违约概率在5s之内,对计算机网络性能的分析和随机网络演算的应用具有指导意义。
On account of delay on the network system performance indicators, a framework of analyzing delay of single node server is constructed by setting up ON/OFF Markov traffic model and constant rate server service model based on stochastic network calculus. Numerical analyses are conducted to prove the effectiveness of the framework by using NS2. The delay in the violation probability is within 5 s. This research will provide a guidance for performance analysis of network and application of stochastic network calculus.
