	SErvice QUality across Independently Managed Networks November 2000 – June 2002
Objective(s)	To define and implement an end-to-end approach to quality of service (QoS) operating across multiple management domains and exploiting a combination of IP and ATM technology.
Achievements	Quality of Service definition based on four criteria: delay, Instantaneous Packet Delay Variation (IPDV), capacity and packet loss Specification of implementation architecture for Premium IP Creation of service level agreement (SLA) template Definition of test beds Execution of user group testing
Milestones	October 2000: kick-off meeting in Zurich to allocate tasks under the various work packages and prepare the way forward. February 2001: more than 10 interviews of network users assessing their QoS requirements were used for a definition of services. April 2001: report to the European Commission detailing the technological approach the SEQUIN team used to develop the parameterised definition of QoS based on four criteria; carrying out of equipment tests. June 2001: first draft SLA for premium IP service 2nd half 2001: carrying out of tests on test beds February 2002: workshop held to disseminate results of the SEQUIN project; to receive feedback; to provide an opportunity for the academic and research community to express requirements for network QoS in view of future planning.
