Abstract :
We focus on RSVP-based resource reservations in a heterogeneous environment which includes ATM networks. We describe a method for establishing shortcuts for the data flow through an ATM network which avoids the performance penalty associated with layer 3 processing in the classical IP over ATM approach. For the guaranteed and controlled-load types of services we show how to map the RSVP flow characteristics to ATM call parameters, and thus enable end-to-end quality of service. Finally, we discuss some concerns which have been raised regarding the use of RSVP in establishing shortcuts
