一种多媒体计算机网络互连节点动态流控模型分析

摘要

This paper proposes a new dynamic traffic controlling police on interconnecting node,based on various rate controlling serving scheme to meet QoS requirements as multi-media being transported,this controlling model is formed by asymmetric dual-queuing exhausting polling system.. Furthermore this paper gives exactly performance analysis about the model,by the embedded Markov chain and the probability generation function method. The formula of the mean cell waiting time and mean queue length are obtained as well as the simulation results are given. This indicates that the model is much effective for image/voice integrated transmission,and has more importance for traffic control on integrated service Internet.%文章提出一种基于信息分组变速率控制服务机制的网络互连节点流控策略，以适应多媒体网络传输的QoS要求，节点模型按照非对称双队列周期查询式完全服务排队系统构成。利用嵌入马尔可夫链理论和概率母函数的分析方法，还给出了信息分组的平均排队队长和平均时延的解析表达式，并进行了计算机仿真实验，结果表明该模型能较好地实现图像/声音的集成传输，这对进一步研究综合业务Internet中的流控机制有积极意义。
