Sammanfattning
Last few years services as Internet Protocol Television (IPTV) has been in focus. Network operators see a huge potential of streaming video over IP {networks and this lays the ground for charged services as Video on Demand (VOD) and free services as YouTube. The benet over such a service can be put in to one word, exible, watch what you want, when you want and where you want. But this type of services also have some drawbacks. IPTV can be sent in logical channels by the operator, but streaming video from YouTube for an exampel have to rely on the best-eort channel. In both cases problem such as packet loss, delay and jitter in the network badly eects the quality for the custumer. This paper descripes dierent technices to estimate the dynamics of an access link. This is done by both active and passive probing. A comparison of measurement results will then be presented.
