Integrated services internet with RSVP over ATM short cuts: Implementation and performance evaluation
This article describes the architecture and initial experiences in implementing an integrated Services Internet with RSVP over ATM short Cuts (ISAC). Our design combines link-layer switching and network-layer routing technologies to provide high throughput data transport and support the Integrated Services model. Our proposed architecture adopts resource reservation protocol (RSVP) as the major signaling protocol and eliminates duplication of functionality in the ATM domain. It also considers the native RSVP heterogeneous multicasting issue. Our proposed ISAC router consists of a core ATM switch connected to a router controller. The controller is responsible for the native IP routing, RSVP signaling and resource management whereas the underlying ATM switch is solely responsible for switching data packets. We have built a prototype network using off-the-shelf ATM switches and workstations. To verify its functionality, we have demonstrated an end-to-end videoconferencing application. We have also conducted preliminary performance evaluation on signaling and control latency as well as transfer delay of the data path. (C) 1999 Elsevier Science B.V. All rights reserved.
