基于多服务器的轮询接入控制协议分析

Analysis of polling access control protocol based on multi-server

为解决现有轮询接入控制协议网络时延高、系统性能差的问题,提出一种同步方式的多服务器轮询接入协议。使用多服务器并发处理的方式实现负载均衡,多个服务器调度时,利用同步控制策略解决多服务器在各个站点之间的轮询问题;在单服务器分析的基础上,运用轮询系统的基本理论和随机过程对系统的平均时延等参数进行解析。通过仿真实验,对理论分析进行验证并对该协议的运行状况进行分析,实验结果表明,该协议比传统的轮询协议性能更好,平均时延更低,网络效率更高。

To solve the problems of high network delay and poor system performance of the existing polling access control protocol,a synchronous multi-server polling access protocol was proposed.Multi-server concurrent processing was used to achieve load balancing.When multiple services were scheduled,synchronization control strategy was used to solve the problem of multi-server polling among various sites.Based on the single server analysis,the average delay and other parameters of the system were analyzed using the basic theory of polling system and stochastic process.Through simulation experiments,the theoretical analysis was verified and the operation status of the protocol was analyzed.Experimental results show that the proposed protocol has better performance,lower average delay and higher network efficiency than the traditional polling protocol.
