【摘要】:针对分组传送网承载电力通信时分复用业务存在时延抖动问题,提出了随机封装和固定封装两种分组封装模式,建立了两种模式的单节点和串联路径端到端时延抖动数学模型.根据创建的两种模型,仿真研究了背景流量、网络节点数量、节点吞吐量和封装模式等参数对时延抖动的影响.结果表明,合理配置这几个参数可以优化网络性能,为去抖动缓存的设置提供依据;而且固定封装模式具有较强的抗抖动能力.
[Abstract]:In order to solve the problem of delay jitter in time division multiplexing (TDM) service in packet-transport networks, two packet encapsulation modes, random encapsulation and fixed encapsulation, are proposed. The mathematical models of end-to-end delay jitter in two modes are established. According to the two models, the background traffic and the number of network nodes are simulated. The effect of node throughput and encapsulation mode on delay jitter. The results show that the reasonable configuration of these parameters can optimize the network performance and provide the basis for the setting of de-jitter buffer. And the fixed encapsulation mode has strong anti-jitter ability.
