摘要
目前建立的网络仿真模型分析的网络延迟变化基本状态范围较小,难以确定通信网络信道通信过程,导致目前方法分析网络延迟精度低,针对这一问题,提出非同步多点通信网络延迟特性SystemView仿真分析。采用SystemView仿真平台,根据非同步多点通信分布式拓扑结构,确定网络端点之间的连通方式,构建通信网络仿真模型;计算通信网络节点距离和信道信号频谱,在通信网络仿真模型中建立非同步多点通信网络信道;分析通信网络通信周期、通信层次和通信顺序,确定通信网络信道通信过程,采用gamma分布拟合非同步多点通信网络延迟时间,仿真描述非同步多点通信网络延迟特性。实验结果表明研究方法相较两组目前方法,受通信网络数据包、占空比、网络延迟等变化影响较小,具有较高的网络延迟分析精度。
The traditional network simulation model has low accuracy in analyzing network delay. In this paper,the simulation analysis of the delay characteristics of asynchronous multipoint communication networks was designed using System View simulation platform. Based on the distributed topology of asynchronous multipoint communication,the connection mode between network endpoints was determined, and the communication network simulation model was established. In the communication network simulation model, the communication network node distance and channel signal spectrum were calculated, and the asynchronous multipoint communication network channel was also founded. The communication cycle, communication level and communication sequence of the communication network were investigated in detail to determine the communication process of the communication network channel. Gamma was utilized to fit the delay time of asynchronous multipoint communication networks. The delay characteristics of asynchronous multipoint communication networks were characterized by simulation. The experimental results show that the communication network packet, duty cycle, network delay and analysis accuracy of this method are superior to those of the traditional method.
