Traffic-Controlled Rate-Monotonic Priority Scheduling of ATM Cells

Future integrated services networks are expected to carry various types of traac including real-time packet video for which stringent quality of service (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 eecient in terms of accommodating channel requests. The scheme employs the leaky bucket model as the input traac description model and regulates the input traac at User Network Interface (UNI) to comply with the input traac spec-iication. Inside the network ATM switches provide bounded local delays to individual cells using a traac controller and a non-preemptive rate-monotonic priority scheduler.
