一种基于移动代理的P2P系统主动负载均衡算法

An Active Load Balancing Algorithm for P2P System Based on Mobile Agent

负载均衡是P2P系统的研究热点,针对现有负载均衡算法的不足,提出了一种基于移动代理的主动负载均衡算法.该算法使用移动代理收集负载信息、生成负载迁移决策,降低了系统的通信开销,而且避免了单点失效问题和"颠簸"现象.通过引入对用户请求的评估和迁移,预见性的处理负载问题,提高了系统的服务质量.

Load balancing is the research focus of P2P system.Aiming at the shortage of existed load balancing algorithm,an active load balancing agent based on mobile is proposed.The algorithm collects load information using mobile agent,generates load migration decisions,reducing the system＇s communication costs,and avoid single point failures and the ＂bumps＂ phenomenon.In order to processing load problem predictability,the assessment and migration of user requests are introduced,which improve system quality of service.
