1821: Integration of Real-time Services in an IP-ATM Network Architecture.

The IETF is currently developing an integrated service model which is designed to support real-time services on the Internet. Concurrently, the ATM Forum is developing Asynchronous Transfer Mode networking which similarly provides real-time networking support. The use of ATM in the Internet as a link layer protocol is already occurring, and both the IETF and the ATM Forum are producing specifications for IP over ATM. The purpose of this paper is to provide a clear statement of what issues need to be addressed in interfacing the IP integrated services environment with an ATM service environment so as to create a seamless interface between the two in support of end users desiring real-time networking services.
