Abstract:

IPTV data transport quality monitoring is one of the most important technologies that must be studied for the deployment of this application. According to the access network with tree topology, this paper proposes a new method for transport quality monitoring based on perhop delay variation detection. With the realtime and continuous attributes of IPTV streams, this method can be used to measure the output port queue lengths and congestion points in a switch. Our analysis shows that this method is scalable and easy to be deployed in the network.
