为了准确地分析、判断无线网络传输控制协议(TCP)性能上界,以提高无线网络在数据传输上的服务质量(QoS),在综合分析无线网络特性的基础上,运用马尔科夫理论对无线网络TCP数据流的随机延迟上界、随机延迟抖动上界以及随机吞吐量理论上界进行了建模,并提出了一种基于随机网络演算的无线网络TCP性能上界的模型。该模型可以简化无线网络流量复杂性分析,而且能够给出网络数据流到达曲线、服务曲线、延迟上界、延迟抖动上界及吞吐量上界。研究表明,用这一模型,可以准确地预测无线网络TCP性能边界情况,这对进行无线网络TCP性能分析有重要意义。 In order to accurately analyze and judge the performance upper bound of TCP (TCP) in order to improve the quality of service (QoS) of data transmission in wireless networks, based on the comprehensive analysis of wireless network characteristics, The upper bound of random delay, the upper bound of random delay jitter and the theoretical upper bound of random throughput of TCP traffic are modeled, and a model of upper bound of TCP performance for wireless network based on stochastic network calculus is proposed. The model can simplify the analysis of wireless network traffic complexity, and can give the network data stream arrival curve, service curve, delay upper bound, delay jitter upper bound and throughput upper bound. The research shows that using this model, we can accurately predict the performance of the wireless network TCP performance boundary, which is of great significance for the wireless network TCP performance analysis.
