Abstract: A method of measuring bandwidth of each link in a remote network is proposed. The idea of bandwidth measurement is introduced. The steps of collecting exploring data and getting bandwidth based on those data are listed. Some key problems including how to structure exploring data, how to reduce the number of exploring packets, the parallel schedule mechanism and the steps of regression are discussed. Experimental results are presented, based on which the influence of exploring speed and the queue strategy of packet on the accuracy of the result are analyzed.

Key words: bandwidth measurement, linear regression, parallel schedule
