Advanced architecture for INTER-domain quality of service MONitoring, modelling and visualisation (InterMON)

Abstract

InterMON was an EU-IST project with 12 participants from several European countries within the 5th Framework Program of the EU. It aimed to develop an architecture for monitoring, modeling, simulation and visualization of inter-domain quality of service. University of Bern was leading work package 5, which was concerned with developing efficient modeling and simulation techniques to support scalable simulation of large inter-networks.

The main focus of the work package 5 during this final phase of the project was on the integration of the various tools in the Intermon simulation toolkit with the global architecture, and on evaluation of these tools. The deliverable "Evaluation of Inter-Domain QoS Modeling, Simulation and Optimization" describes the evaluation work. Contributions to several other deliverables have also been made, see Intermon deliverables at technical reports section.

The "hybrid simulation" concept developed by the University of Bern achieves scalability by combining analytical models for network domain clouds (usually autonomous systems) and inter-domain links with classical packet-based simulation techniques. A mechanism to integrate these analytical models into the packet-based ns-2 simulator has been implemented. The resulting hybrid simulator and its integration into the Intermon architecture have been successfully tested and evaluated using two testbed networks, located at Salzburg Research and the University of Bern, respectively.
