| Abstract: | 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. |
