IP multicast was developed and implemented for the use of the real time transmissions over the Internet e.g. audio- or video transmission. In order to guarantee these new services, a minimum quality of service is necessary for the transmission of those high quality multimedia data. Measurements of the quality of service in multicast network is necessary, in order to become simply overview of the current behavior of the communication network, e.g. in order to answer the question whether a real-time application can be used in desired quality. For the measurement of quality of service characteristics of IP multicast networks was a Tool the Multicast Quality Monitor (MQM) introduced, MQM consists of two different concepts. The MQM Ping mechanism of it initiates the different hosts, which have an active MQM, to answer the requests of other MQMs or to send a request message to an IP multicast address. The valid timestamps of the sending process are registered in the messages, therefore all receivers of these response messages know the relevant timestamps of sending and receiving. These timestamps are used for measuring transmission times to state the quality and functionality of the IP multicast network. The master thesis gives a short introduction to the three important QoS characteristics, which are limited the multicast IP world. Subsequently, the concept and the implementation of the tool MQM are described. Finally the MQM mechanism is implemented in two simulation environments Anylogic and OMNeT++ and plotted with the help of the MQMs collected information the number of MQM messages in a multicast net with different loss rate of the individual connections. The OoS characteristics One Way Delay and paket loss ratio come thereby also into view.
