摘要： 为了实现服务网格系统内负载的均衡分布，提高资源利用率和系统的吞吐率，设计并实现了一种基于服务网格环境的动态负载平衡系统。提出了层次式负载平衡调度模式，给出了本系统结构形式，设计并实现了一种综合考虑各局部代理作业数和各个局部代理性能以及当前的负载情况的动态双阈值作业分配算法。实验结果表明，此算法能有效地基于负载分派作业，达到了提高网格内分布资源的利用率和减少作业调度时间的目的。

Abstract: In order to realize load balance distribution and improve resource availability and throughput rate of a service grid system, a dynamic load balance system is designed and implemented. A hierarchical load balance scheduling mode is proposed and the system structure is presented. A dynamic double threshold algorithm for job assigning is designed and implemented by considering the number of jobs and the current load in local agents as well as the performance of these local agents together. The test results show that the algorithm can assign jobs effectively based on load to acquire the improvement of the availability of the distributed resource in the grid system and the decrease of the overall runtime of job scheduling.

Key words: Service grid, Load balance, Load, Job assignment
