针对旧有的兼顾排队任务的资源预留策略只能提高自身节点的任务均衡,而无法在整个网络进行资源均衡使用的问题,提出了一种改进的资源预留策略。当本节点的排队任务平均等待时间剧增时,该策略通过将排队任务转化为预留任务提交到整个网络来减少排队任务的平均等待时间,而且能实现整个网络的负载均衡。实验结果表明,该资源预留策略比旧有的策略在网络资源利用率上有明显的提高。
Aiming at the problem that the old resource reservation strategy that takes into account both queuing tasks can only improve the task balance of its own nodes and can not balance the use of resources in the entire network, an improved resource reservation strategy is proposed. When the average queuing task waiting time of the local node rapidly increases, the strategy reduces the average waiting time of queuing tasks by converting queued tasks into reserved tasks and submits them to the entire network, and can load balance the entire network. The experimental results show that the resource reservation strategy has obviously improved the network resource utilization rate than the old strategy.
