【摘要】 该文提出了一种基于VirtualClock算法的自适应成比例带宽分配算法(ProportionalAdaptiveBandwidthAllo-cationAlgorithmBasedonVirtualClock,PABVC)。该算法将所有的业务流分为绑定流和非绑定流,并根据不同流的配置加以调度,从而实现了绑定带宽同时自适应成比例分配带宽的目的。由于算法的各个部分相关性较弱,所以在保留算法框架和核心部分算法的基础上,可以灵活地加以组合,实现不同的算法变种。最后,该文分析了PABVC算法的优缺点,并且提出了今后的研究重点。更多还原

【Abstract】 A prop or tional adaptive bandwidth allocation algorithm based on VirtualClock(PABVC)is presented in this paper.In PABVC,all of the flows are divided into bounded fl ows or non-bounded flows ,and are scheduled based on their configurations.So PABVC can bound the bandwidth of the bounded flows and is a proportional adapt ive bandwidth allocation algorithm.Because the relationship between the differe nt parts of the algorithm is weak,people can easily assemble the different pa rts but reserving the algorithmic framework and kernel algorithm to realize man y different versions of PABVC.Finally,the advantages,shortcomings and resear ch focus in future of PABVC are presented in this paper.更多还原
