摘要

几家欧洲xDSL运营商已经或准备推出视频over DSL服务，其中DSL链路由数据服务(IP、UDP和TCP)和视频通道(通常是MPEG-2流)共享。由于视频通常通过分配更高的优先级(通过基于类的调度规则)来获得青睐，TCP使自己适应视频流的分形特性，众所周知，视频流具有高水平的分形。本文建立了ns-2仿真，分析了DSL链路中视频和数据流量的相互影响，验证了分形传播现象。本文还解释了从一个交通流传输到另一个交通流的数据的分形。

On the mutual influence of data and video traffic in video-over-DSL services

Several European xDSL operators have launched or are going to launch video-over-DSL services in which the DSL link is shared by a data service (IP, UDP and TCP) and a video channel (typically an MPEG-2 flow). Since video is usually favored by assigning a higher priority (via a class-based scheduling discipline), TCP adapts itself to the fractal properties of the video flow, which is known to have a high level of fractality. This paper sets up a ns-2 simulation for the analysis of the mutual influence of video and data traffic in a DSL link and verifies the fractality propagation phenomenon. This paper also explains the fractality of the data transmitted from one traffic flow to another.
