| 摘 要： | 为了分析比较集群负载均衡中随机调度算法、轮转算法、加权轮转算法等3种基本算法,介绍了OPNET的建模方法,给出了基于OPNET进行网络仿真的建模层次和步骤,并运用OPNET建立集群系统模型,对其进行仿真测试.仿真结果表明:3种算法均能实现负载的平衡分配,在同构集群中,轮转算法有较好的负载均衡效果;但在异构的集群系统中,加权轮转算法具有最好负载均衡效果.

| Abstract: | In order to compare and analyze the performance of three load balancing algorithms in cluster system: Random,Round-Robin and Weighted Round-Robin,the modeling methods and steps of the network simulation based on OPNET are presented in this paper.The three algorithms are built up based on OPNET,which can realize simulation of the performance of the cluster.The simulation results indicate that all of the three algorithms can achieve a balanced distribution of workload,and the Round-Robin algorithm has better ... |
