摘要: 针对分布式系统负载平衡问题,对动态全局最优策略进行改进,结合静态全局最优策略,提出动静结合的负载平衡策略。策略克服在较高通信开销时动态负载平衡策略的缺点,有效提高分布式系统的综合性能。仿真结果表明,使用该策略在通信开销较高和系统负载率大于40%的情况下,能够获得比动态负载平衡更小的系统预期响应时间。

关键词: 负载平衡, 动静结合, 通信开销

Abstract: This paper improves dynamic global optimal scheme according to problem of load balance in distributed systems, and proposes a new scheme which is combined with dynamic scheme and static scheme. When the system is in high communication overhead, the new scheme overcomes the disadvantage of dynamic load balance scheme and enhances the comprehensive properties of system effectively.

Key words: load balance, dynamic and static, communication overhead
