Abstract. In the area of network monitoring a lot of tools are already available to measure a variety of metrics. However, these tools are often limited to a single administrative domain so that no established methodology for the monitoring of network connections spanning over multiple domains currently exists. In addition, these tools only monitor the network from a technical point of view without providing meaningful network performance indicators for different user groups. These indicators should be derived from the measured basic metrics.In this paper a Service Oriented Architecture is presented which is able to perform multi-domain measurements without being limited to specific kinds of metrics. A Service Oriented Architecture has been chosen as it allows for increased flexibility and scalability in comparison to traditional software engineering techniques.

We propose the creation of a multi-domain measurement framework with dynamic characteristics identical to that of the network as a whole. Our approach recognises and facilitates the ability of independent network entities to set policies and limits on the use of measurement resources locally while encouraging and facilitating the use of such resources by users interested in network paths that traverse remote administrative domains.
