Method for evaluating the bandwith of a digital link

摘要

The invention relates to a method for evaluating the bandwidth between a first point and a second point liable to exchange digital data packets in a telecommunications network including a plurality of sub-networks. The method according to the invention includes the following steps: for each transmission direction through at least one of said sub-networks, associating a same identifier with the quasi-simultaneously transmitted packets, time-stamping and recording the received packets, identifying and sorting the packets received with the same identifier, selecting the largest possible integral number m of groups of packets with the same identifier, measuring the time intervals separating the instants when the packets of the selected groups are received by the second point, calculating the bandwidth according to the number of packets of the selected groups and to said total transmission time of said packets.
