Abstract

Future integrated services networks are expected to carry various types of traffic including real-time packet video for which stringent quality of servicle (QoS) requirements must be met. In this paper, we propose a cell multiplexing scheme for providing real-time communication services in point-to-point ATM networks. Our scheme is simple enough to be used in high-speed ATM networks, yet reasonably efficient in terms of accommodating channel requests. The scheime employs the leaky bucket model as the input traffic description model and regulates the input traffic at User Network Interface (UNI) to comply with the input traffic specification. Inside the network ATM switches provide bounded local delays to individual cells using a traffic controller and a non-preemptive rate-monotonic priority scheduler.
