| 摘 要： | 提出一种与现有带宽测量方法(包对法)不同的探测理论——基于链路状态的带宽测量方法。源端向目的端发送一系列小的探测报文,通过对探测报文的时延参数进行数理统计得到链路忙闲状态,进而获得链路可用带宽。采用此方法也可用于计算各种链路容量和链路空闲率。在实际测量中为解决探测报文与背景业务之间的相互影响,利用IPv6基本报头中流标签和业务类型字段设计专门的测试流和测试级。仿真证明方法正确。

| Abstract: | A novel approach to available bandwidth measurement based on the link status is proposed, which is different from the packet train method. The source sends small packets as probes instead of sending packet pair/train back-to-back to achieve the link status and the available bandwidth. This method can measure the capacity and idle ratio of the targeted link. Meanwhile, in order to resolve the influence of cross traffic, the "test stream" and "test level" are designed using the corresponding fields in the IPv6 basic header. This approach is verified through simulations. |
