摘    要:利用IPv6报文头部的流标签字段和业务流类别字段,通过增设专门用于网络测量的“测试级”,提出了一种IPv6网络中的端到端可用带宽测量方法——Hurnble-Burst.该方法对网络中已有的业务流不产生任何影响,并且测量时间非常短.与现有网络中可用带宽测量方法相比,该方法可以真正被实际应用程序所采用,可以应用在无线网络等低带宽的网络环境,而且也适用于多媒体QoS动态调节等实时场景.实验表明,该方法简单、有效、快速,并对网络本身无影响.

关 键 词:可用带宽  瓶颈带宽  IPv6

Abstract:Making use of flow label and traffic class fields in the IPv6 header, an original end-to-end measurement method, called Humble-Burst, is presented to estimate available bandwidth in IPv6 networks. This method overcomes some of the problems common to many types of the existing probing methods, e.g., the long latency and large probe traffic; thus it can be applied to many real-time applications. This method is evaluated in different scenarios using NS2. And simulations show this method is accurate, efficient, quick and really non-intrusive, i.e., without affecting the existing traffic in the path.
Keywords:available bandwidth  bottleneck bandwidth  IPv6
