摘要
目的 提出一种分布式的边对边QoS测量方法,以获取QoS参数信息。方法 提出边对边DS流模型,在DS域中构造DS流,通过DS流中的网络中间节点获取QoS参数信息,并对其进行聚合得出DS流的QoS参数特性。结果 通过ns 2网络模拟器模拟的结果证明该方法测量结果良好,并且使用较少的网络资源。结论 是一种有效的QoS信息获取的方法,同时对QoS管理也具有重要的意义。
Aim A distributed edge-to-edge method which will be used to measure QoS parameters is proposed.Methods First an edge-to-edge DS flow model is established, which will be used to construct DS flow in a DS domain. And then get QoS parameters from the nodes forming the DS flow and aggregate them for the characteristics of DS flow. Results Based on the ns-2 emulator, the method has been proved that the measured results from the method is more efficient and waste less network resources. Conclusion The method is a good way to get QoS information, and it can also be meaningful to QoS management.
