Abstract
A method for measuring delay parameters in a packet switched network between node A and node B, each having a clock, is disclosed The method includes the steps of: measuring a first relative one way delay (ROWD1) from node A to node B, measuring a second relative one way delay (ROWD2) from nude B to node A and calculating the difference between the first and second relative one way delays for providing a relative one way delay (ROWD) parameter. Methods for improving TCP protocol and detecting congestion in a packet switched network using ROWD measurements are also provided.
