自相似混合业务流的网络性能研究

Analysis on Network Performances based on Self-similarity Hybrid Traffic Flow

针对传统业务流量模型的网络性能结论不能完全适用于多路自相似业务混合流量的智能电力通信网络,首先介绍基于分形布朗运动的单一自相似业务流模型,接着分析多路输入自相似业务的合成流量模型,然后研究多路输入自相似流的网络性能,最后给出智能电力通信网中4类通信业务的QoS要求,其中通信业务的QoS要求和多路输入自相似混合流的网络性能计算,可为智能电力通信网的进一步研究提供参考。

In view of the conclusion that the network performance of traditional traffic flow model could not be fully applicable to the intelligent electric power communication network with multi-path self-similar traffic hybrid flow model, this paper first gives the single self-similar traffic flow model based the fractional Brownian motion, then analyzes the hybrid flow model of multiple inputting self-similar traffics and discusses the network performance based on multiple inputting self-similar flow, and finally describes the QoS requirements by four communication services in intelligent electric power communication network. The QoS requirements by communication services and the network performance calculations of multi-path self-similar traffic hybrid flow could provide a reference for further studying the intelligent electric power communications network.
