摘　　要：近年来,因特网上P2P文件交换的流行,使网络的时延和拥塞的情况增加,对实时音频和视频等时延敏感的应用提出了巨大的挑战.研究了P2P流、音频流和视频流的共存问题,提出了网络控制和用户控制2种P2P带宽控制的方法.In the recent years, the use of Peer-to-Peer （P2P） applications for file exchange has increasingly gained popularity in the Interact., which increase the congestion level and delay in the network. The coexistence of these greedy applications with delayed sensitive applications such as real - time audio or video is very challenging. This pape studies the coexistence of P2P traffic with audio and video applications and analyzes two ways for controlling the P2P bandwidth consumption： network-controlled and user-controlled ways.
