Abstract

The invention discloses a method and a device for measuring a bottleneck bandwidth. The method comprises the steps of receiving m data packet sets which are sequentially sent from a second data end to the first data end by the first data end, wherein m is greater than or equal to 1; by the first data end, obtaining a section of continuous data packets with the sending interval satisfying a preset interval from each data packet set to serve as a first sub-set of the data packet set so as to obtain m first sub-sets; and, by the first data end, obtaining a bottleneck bandwidth between the first data end and the second data end based on the total byte number of each first sub-set and time taken for receiving each first sub-set. According to the method and the device for measuring the bottleneck bandwidth, the technical problem of a relatively big measurement error of the bottleneck bandwidth between the two ends is solved.

Description

technical field [0001] The present invention relates to the Internet field, in particular to a method and device for measuring bottleneck bandwidth. Background technique [0002] In the process of testing the transmission speed of the network, the method of packet pair speed measurement can be used. Packet pair speed measurement means that one data terminal sends a pair of data packets at intervals, and the transmission speed of the network is determined according to the time when another data terminal receives the pair of data packets. Using the method of packet pair speed measurement, if two data packets are back-to-back at the bottleneck link, the two packets need to wait in line when passing through the link bottleneck, and there will be a certain interval between the receiving time of the two packets. This interval is determined by the packet size and The bottleneck bandwidth is determined, therefore, the transmission speed of the network can be determined according to...
