一种面向云计算的分态式自适应负载均衡策略
A Sub-state Adaptive Load Balancing Strategy for Cloud Computing
摘要
Abstract
In cloud computing systems, large parallel tasks may lead to overloaded for some nodes and cause the load unbalanced and inefficient for the system. A sub-state adaptive load balancing strategy is proposed for cloud computing system. The strategy judges the state of load by load degree. When a node is in the mild or severe overloading status, it spontaneously runs overload avoiding or quickly balancing method. The strategy adjusts the effectiveness degree of the node dynamically, so that mild overloading nodes can avoid severe overloading and severe overloading nodes can return to normal load quickly. The experiment results show that the sub-state adaptive load balancing strategy ensures the load balancing and efficientive performance in cloud computing systems.关键词
