Service Quality across Independently Managed Networks (SEQUIN)

Abstract

SEQUIN was an EU-IST project involving eight partners (mainly national research network providers) in seven European countries and running from November 2000 to April 2002. The main goal of this project has been to define and implement an end-to-end QoS approach to operate across multiple management domains combining distinct network technologies. In this way, SEQUIN would ensure that researchers across Europe had access to network facilities that could be tailored to the requirements of individual groups. As an overall view, the project has been successful in defining an achievable QoS model by taking into account the user requirements and the capabilities of emerging technologies. Additionally, such a definition has been evaluated in a pilot environment involving purely experimental networks as well as production networks. During the whole project, University of Bern has supported SWITCH in two aspects mainly: test-bed set-up / measurements and tool development / configuration for QoS monitoring. In particular, QoS measurements have been performed over international test-beds. The goal of has been to determine the real capacity of the networks in place. Another task was the investigation of effective QoS monitoring tools to be used by SEQUIN. The main outcome was the demand for very specific QoS monitoring tools. This can be met by developing tailored tools or upgrading the existing ones toward the needs of this project.
