即时通讯系统中负载均衡策略的研究

Study of Load Balancing Strategy in Instant Messaging System

通过对Zomaya遗传算法的改进,设计了针对即时通讯系统的负载均衡策略。介绍了基于遗传算法的负载均衡策略的实现过程和负载均衡系统的结构和主要部件。最后通过仿真试验的结果证明,该负载均衡策略能够较好地解决在大任务量的情况下,即时通讯系统中异构节点间的负载平衡问题,提高系统的整体处理能力、反应速度和稳定性。

By improving the Zomaya genetic algorithm, A load balancing strategy aiming at instant messaging system is presented. The realization process of load balancing strategy which is based on genetic algorithm is introduced, as well as its structure and major components. The emulation experiment in the end of the paper proves that the load balancing strategy can solve the problem of load balaneing among heterogeneous nodes in the instant messaging system under heavy workload, and the holistic processing capacity, reaction speed and stability of the system can be improved with the strategy as well.
