摘　　要：长期以来,人们一直关注着网络瓶颈带宽的测量,提出了诸如变长包序列(VariablePacketSize,VPS)模型、包对(PacketPair)模型的算法,但由于网络中存在着许多不确定的因素,它仍然一直是困扰人们的一大网络难题。文章针对目前已有的算法及测量工具中存在的缺陷,如测量开销过大、测量时间过长及对网络设备的考虑不够等方面,提出综合VPS和包对模型的算法,并结合实际网管系统的开发,完成初步的设计与实现,最后就测量结果进行分析,并提出应用与推广。The bottleneck bandwidth of the network is cared about all along and many models such as VPS(Variable Packet Size)and Packet Pair are put forward.Because of many unstable factors,it yet is a puzzling problem.The article presents algorithms integrating the idea of VPS and Packet Pair,in allusion to many limitations such as too much bandwidth overhead,too long time and inadequate consideration of devices,in existed algorithms and tools.Then it pre-sents initial design and realization according to the development of network management system.Finally,it makes some measurements and analyses,and brings forward some applications and extension.
