Provisioning of RSVP-based Services over a Large ATM Network

In this work we address the problem of ow establishment with QoS constraints and reservation of resources in an IP network that spans over ATM networks. Speci cally, we study the interaction and integration of the RSVP protocol using Integrated Services ow speci cations with the ATM signaling. Among the issues raised by such an integration are: the interaction between the ow/call establishment protocols, and the translation between ow/call characteristics. For these issues we sketch several possible solutions rather than focus on a particular design. Finally we discuss the extensions to RSVP and to the ATM signaling required for the implementation of these solutions. Part of this work was done while visiting the IBM T.J. Watson Research Center
