| Abstract | Video streaming services using Transmission Control Protocol (TCP) as a transport layerprotocol---represented by YouTube---are becoming increasingly popular and,accordingly, have come to account for asignificant portion of Internet traffic. TCP is greedy; that is, it tries to exhaust theentire bandwidth.Thus, video streaming over TCP tends to unnecessarilytake bandwidth from competing traffic. In this paper, we first investigate the data transfer mechanisms of the currentvideo streaming services using TCP and showthat they perform data transfer at much higher rates than the video playback rate.We then propose a new transfer mechanism for video streaming over TCP,one that controls the data transfer ratebased on the network congestion level and the amount of buffered video data at the receiver.Simulation results show that the proposed mechanism has two characteristics lacked bycurrent video streaming over TCP, specifically (1) a low frequency of buffer underflow at the receiverand (2) a lack of excessive bandwidth ``stealing from competing traffic. |
