Abstract

With the increasing number of users of broadband digital trunking communication systems, the architecture of the digital trunking communication system is shifting from a centralized architecture to a distributed architecture. In order to balance the load of multiple media servers and reduce the delay of voice forwarding in a distributed trunking communication system, this paper proposed a load balancing algorithm for media server in distributed trunking communication system. According to the linear relationship between the load increment of the media server and the number of participants in the call, the algorithm establishes the load prediction model of the media server, predicts and adjusts the load of multiple media servers in the distributed trunking communication system in real time, and selects the media server with the least load for voice rewarding. Theoretical analysis and experimental results show that the algorithm has lower response time and better load balancing effect compared with the traditional load balancing algorithm.

分布式集群通信系统中媒体服务器的负载均衡算法

随着宽带数字集群通信系统用户的不断增加，数字集群通信系统的体系结构正从集中式体系结构向分布式体系结构转变。为了均衡分布式集群通信系统中多个媒体服务器的负载，降低语音转发的延迟，本文提出了一种分布式集群通信系统中媒体服务器的负载均衡算法。该算法根据媒体服务器的负载增量与呼叫参与人数的线性关系，建立媒体服务器的负载预测模型，实时预测和调整分布式集群通信系统中多个媒体服务器的负载，选择负载最小的媒体服务器进行语音奖励。理论分析和实验结果表明，与传统负载均衡算法相比，该算法具有更短的响应时间和更好的负载均衡效果。
