摘　　要：通过改进瓶颈带宽测量基本算法得到了在IPv6环境下基于减法模型的非对称包对算法。该算法充分利用了IPv6环境下的新特性,使用IPv6包头的流标签来实现测量报文序列的严格路径控制,克服了以往带宽测量算法中测量数据报文路径不一致的缺陷,同时消除了数据包排队和网络协议对带宽测量带来的影响。In this paper,the asymmetric algorithms package （Asymmetric Packet Pair Under Subtraction Module,APP） was obtained by improving bottleneck bandwidth measuring method,based on the subtraction module. Subtration based APP takes full advantage of the new features of IPv6. The flow label in the IPv6 packet head structure is used to ensure that the measured path is unique. This overcomes the defect caused by multi-channel of network path,such as,measuring all the links of bandwidth along the measured path,and eliminates the uncertainty caused by packet queuing and all kinds of network protocols.
