另外，根据本文提出的视频流量模型实现了一个内嵌于ns - 2的视频流量产生器，并用它进行了网络仿真验证。

Moreover, this paper implemented a video traffic generator embedded in NS-2 according to the model proposed in this paper. And it is applied to network simulation.

视频业务流量模型是网络性能仿真的一个重要前置环节，但由于视频内容的千差万别，使得很难建立统一的视频业务流量模型。

Modeling video traffic is an important prerequisite for any network performance simulating, but it is very difficult to build an uniform model for video traffic since video contents are variable.

以视频码流流量的实测包络为基础，提出了一种流量描述模型。

Based on the empirical envelope of a compressed video stream, a traffic description model was developed.
