| 摘 要： | 为了改进在分布式环境下用于QoS控制的基于模糊逻辑的动态资源调配算法(FDRA),提出了基于双阈值和双指针的自适应动态控制资源算法--EFDRA(Enhanced FDRA),解决了当网络资源紧张时,FDRA算法更新指教上升过大的问题.仿真结果证明,该算法以牺牲少量的阻塞率指标为代价,换来了更新指数指标的显著改善,提高了网络的可扩展性能.

| Abstract: | Although the algorithm of fuzzy-logic based distributed dynamic resource allocation (FDRA) demonstrates a good performance,it has the problem of updating rate increase when the network is short of resources.To overcome this problem,an enhanced adaptive dynamic resource allocation algorithm,enhanced FDRA (EFDRA),is proposed based on the idea of dual-threshold and dual-pointer.Simulation result and analysis are presented.They show that the proposed algorithm substantially reduces the updating rate at the cost... |
