| Abstract(in English) | In the Internet, video streaming service in which users can enjoy videos at home is becoming popular. Video streaming with HDTV or UHDV class quality will be also provided in future. However, the transmission bit-rate of HDTV or UHDV is quite large, so traffic flows generated by this service will cause link congestion. To alleviate the impact caused by this bandwidth-demanded service on the Internet, it is important to mitigate the traffic concentration and balance the load on each link in the network. One simple approach to achieve this goal is to provide multiple video servers over the network and download video from multiple servers to one user. However, the effectiveness of parallel download will strongly depend on the network topology. In this paper, we numerically evaluate the performance of parallel download using the actual topologies of 23 commercial ISP backbone networks. We clarify the conditions required for network topology to effectively decrease the variation of link load without increasing the average link load. |
