【摘要】 在分析现有集群服务器调度机制的基础上,提出一种服务器申请、均衡器调度的合作方式集群体系结构。该体系结构摒弃了传统的均衡器主动式负载均衡工作方式,将接受任务的主动权交给节点服务器,消除了高负载下服务器的“活锁”现象,提高了服务器的有效利用率;同时保留均衡器选择服务器的权利,保障了分发任务的正确性和服务器的负载均衡,给予均衡器动态优先选择任务的权利,保障服务最短响应时间和服务的公平性。更多还原

【Abstract】 Based on the analysis of the schedule mechanism used in current cluster server systems, the cluster architecture is presented, which is based on a cooperative way of server application and director distribution. The cluster architecture has abandoned the traditional director active load balancing working way, accept initiative of task for the nod server, dispel the “living locking” phenomenon of the server under high load, have improved the effective rate of utilization of the server, kept the director right of choosing server at the same time, ensured the exactness of tasks’ distribution and the load balancing of server, offer the director right of dynamic prior choice tasks, ensure serving the shortest response time and the fairness of service.更多还原
