IP Phone系统中组播通信Agent的设计与实现

The Design and Implementation of Multicast Communication Agent in an IP Phone System

提出了一个具有实时负载均衡和快速异常处理功能的组播通信Agent(MCA)。该Agent充分利用组播通信的优点,通过负载均衡算法,对IPPhone系统中各个服务器进行资源分配和调度,并且对异常情况做到快速处理和恢复。首先给出了MCA的组成结构,然后重点描述各模块的功能和实现,最后通过模拟实验,对MCA进行了性能分析。

This paper proposes a multicast communication agent (MCA), which has the capabilities of realtime load balancing and rapid exception processing. The agent makes use of the advantages of multicast communication, by means of load balancing algorithm, distributes resources and schedules to each server in an IP Phone system, and rapidly processes and recovers when occurring exception. In this paper, we firstly introduce architecture of MCA, then emphatically describe the function and realization of every module, finally analyze the performance of MCA by way of simulative experiment.
