Abstract:
1. A method of monitoring the quality of a real-time communication in a packet network comprising at least two test points, wherein the method comprises the steps of: accessing a packet stream pattern; injecting the packet stream pattern at a first test point; receiving a degraded racket stream pattern at a second test point after transmission of the packet stream pattern through the packet network; determining characteristics of the degraded packet stream pattern; comparing the characteristics of the degraded packet stream pattern with corresponding characteristics of the packet stream pattern injected at the first test point; and evaluating, based on the comparison result, data concerning a signal quality degradation caused by transmission through the packet network by a simulation of a transmission quality of the real-time communication, wherein said comparison result is applied to media streams of a real-time application by modifying a pattern of the media stream, such that it complies with the analysed comparison results and applying the degraded application signal to a method to assess the quality of a deteriorated real-time transmission experienced by a user.
