IP multicast is one of the leading technologies which has an important influence on the contemporary development of new multimedia applications to be used in the internet. Due to the high complexity and the incomplete or possibly unavailable implementations, the operation of IP multicast is still very expensive. In addition, only a few people have the knowledge to operate large multicast networks. Additionally, many multimedia transmissions suffer from the best effort transport model of IP. High quality of service (QoS) demands can be determined in emerging multimedia applications.
Today, it is generally considered that the solution of this problem lies in the development of automation procedures designed to rapidly locate the problem areas in the IP multicast network. The primary goal is a fully automatic test of the multicast functionality including a current network quality of service analysis, with the possibility of an extended service quality forecast.
The goal of the MQM is to introduce a novel approach to solve the mentioned questions which is based on a completely new analysis of the problem. The primary goal is to test the multicast infrastructure starting with the requirements of the most important applications. The functionality, i.e. the connectivity within the network, is measured as well as the quality of service. With the gathered information and measurement results, it will be possible to predict the quality of scheduled applications.
