Bandwidth measurements
by Andrei Sukhov 14 Jul '10

14 Jul '10

Hi Henk, It is again me, Andrei Sukhov. Earlier our team tries to add mechanism of bandwidth measurements to RIPE Test Box data. We found a method how to calculate an available bandwidth from delays of different sizes of packets. Our report has been submitted in Berlin and Lisbon RIPE meetings. After Lisbon we have made additional experiments and compare our results with well-known pathload utility. The area of applicability of our method will be also found. All our results are included in paper that is attached to this letter. I would like to ask how our method may be used in RIPE Test Box for calculation of available bandwidth. Probably we should to make a report on IETF session (in Beijing ?). Please, give us an advice. Sincerely, Andrei Sukhov
