摘要
为了提高网络的服务质量,提出一种基于随机网络演算的网络服务质量分析方法。首先推导出有效的端到端积压和时延边界,使到达流通过的节点数量呈线性增长;然后引入有效带宽和有效容量以延长到达流和服务进程的随机信息保留时间,可以更有效地计算端到端随机性能值;最后采用数据进行仿真实验,测试该方法的性能。结果表明,相对与其他网络服务质量分析方法,随机网络演算方法提高了网络的服务质量。
In order to improve network services quality,we propose a stochastic network calculus-based network services quality analysismethod.First,we deduce the effective end-to-end backlog and delay boundaries,and make the number of nodes passing through the arrivalflow growth linearly;then we introduce effective bandwidth and effective capacity to extend the retaining time of random information of arrivalflow and services process,thereby it is able to more efficiently calculate the end-to-end random performance values.Finally,we carry outsimulation experiment with data to test the performance of method.Results show that compared with other analysis methods of network servicesquality,the stochastic network calculus method improves the services quality of network.
