Multidomain End to End IP QoS and SLA

This paper present the SEQUIN approach to the problem of providing end to end QoS services in the European framework of the GEANT, the European 10Gb/s network backbone, which connects more than 30 National Research and Education Networks (NREN). A multidomain Premium IP service, based on the EF PHB, has been specified and implemented for that environment. Its architecture is summarised here and early experimental results are reported.
