Abstract
A method and a network architecture for mapping Internetworking Protocol (IP) multicast and Integrated Services (i.e. differing levels of quality of service) over asynchronous transfer mode (ATM) networks, based upon multicast switches, allowing IP/resource reservation protocol (RSVP) applications running on ATM hosts to seamlessly participate in Internet-wide multicast sessions. The method and architecture employ ATM capabilities to support features such as receiver heterogeneity, shortcut routing and scalability.
