摘　　要：以音视频为代表的流媒体业务目前已经超过了传统的语音和数据业务,成为挑战城域网承载能力的最大考验。针对流媒体业务的特点提出了一种基于业务类型的统计复用技术,利用此技术可以大大提高城域网的带宽利用率,高效地传输流媒体业务,同时不影响传统语音和数据业务的传输。Instead of traditional voice and data service, streaming media services with audio and video services as representatives has become the biggest challenge for carrying capacity of metropolitan area network. This paper brought forward a service-type based statistics multiplexing technique according to the characteristic of streaming media service. Using this technique, utility of bandwidth in metropolitan area network can be improved greatly and streaming service can be transmitted smoothly without degrading of traditional audio and video service.
