Abstract(in English) | To estimate available bandwidth of high-speed lines with high accuracy, we propose PathRefiner, a bandwidth estimation method with two functions: (1) packet concatenation and (2) iterative resolution refinement. It is one of the so-called packet train methods that estimate usable bandwidth by transmitting multiple estimated packets. (1) The packet concatenation method can virtually generate large packets necessary for estimating available bandwidth on high-speed lines by concatenating multiple packets of MTU size or smaller. (2) The iterative resolution refinement method improves the resolution of estimation and enables highly accurate estimation of available bandwidth while minimizing the communication load for estimation by finding the optimal number C of large-sized virtual packets to be concatenated. As a result, the average value of the relative error between the true value and the estimated value was relatively small (16.8%), confirming that PathRefiner can accurately estimate the available bandwidth of 1 Gbps high-speed lines. |
