| Abstract: | Packet delay traces are important measurements for analyzing end-to-end performance and for designing traffic control algorithms in computer networks. Several algorithms to estimate and remove the relative clock skews from delay measurements based on the computation of convex hulls are presented.These algorithms are greatly improve the accuracy of measurements,and can be used both online and offline. |
