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. The resulting measurement framework will be
applied for measurements in the European Research Network (GÉANT) and connected National Research and Education Networks in
Europe as well as in the United States.
