Dynamic QoS for IP switching using RSVP over IPSOFACTO
This paper explores how dynamic quality-of-service may be supported through RSVP over IPSOFACTO within a network of ATM switches. IPSOFACTO is a methodology fur supporting IP directly over ATM switches. Application endpoints communicate exclusively via IP and no ATM signalling is involved. The application's dynamic QoS requirements are communicated by a user through a novel user interface, called CockpitView, and these are signalled through the network via RSVP running directly on ATM switches. Models to accommodate receiver heterogeneity in this environment are described. A Traffic Control module interfacing to both RSVP signalling and IPSOFACTO is presented. Finally, an experimental setup over the MAY/BALI networks integrating IPSOFACTO, RSVP and CockpitView is presented.
