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。
Through the improvement of Zomaya genetic algorithm, a load balancing strategy for instant messaging system is designed. The implementation process of load balancing strategy based on genetic algorithm and the structure and main components of load balancing system are introduced. Finally, the simulation results show that the load balancing strategy can better solve the problem of load balancing among heterogeneous nodes in instant messaging system under the condition of large workload, and improve the overall processing capacity, response speed and stability of the system .
