This paper proposes an approach to support integrated services Internet with RSVP over ATM shortcuts (ISAC). While similar to other LP switching approaches, our work is different in three major aspects. First, it focuses on supporting the integrated services model whereas other approaches currently support only best effort traffic. Second, our architecture adopts RSVP as the major signaling protocol and eliminates duplication of functionality in the ATM domain. Finally, while heterogeneous multicast has not yet been supported in any other approaches, it is considered in our proposal. Our design strives to achieve three fundamental objectives: (1) ensuring compatibility with existing networking standards, applications and system software, (2) maintaining data path efficiency, and (3) assuring portability for different operating system and switch control protocol. Our proposed architecture has been proven by a prototype implementation. Its operation has been verified by demonstrating a videoconferencing application. Our prototype has also been evaluated by measuring its signaling and control latency as well as the transfer delay of the data path
