Project overview

There has been an increasing interest in being able to measure available network capacity and other network performance characteristics. Internet users need measurement tools to be able to verify that their operator provides the promised service that they pay for. The network operators need measurement tool to run their networks efficiently and to be able to control the offered services. New measurement methods might also open up for new simple mechanisms for quality of service and new business models based on service differentiation.

The goal of the Evalunet project is to develop efficient and accurate methods and tools to measure available network capacity as well as other network characteristics. In the project, methods and tools for end-to-end measurements are investigated as well as methods and tools for network tomography, i.e., large-scale collaborative measurements performed by computers at the network edge. The research includes investigation of:

• how to speed up active path measurements
• how to combine active and monitor-based measurements
• methods for traffic matrix estimation and network tomography
• predictability and temporal properties of network traffic

EvaluNet is a collaboration between Mälardalen University, Swedish Institute of Computer Science and several industrial partners. The project is funded by Vinnova (the Swedish Agency for Innovation Systems) and KK-stiftelsen (The Knowledge Foundation).
