A distributed protocol to schedule and monitor ATM real-time traffic

A service discipline for real-time ATM traffic is presented. End-to-end delay and delay variation bounds are provided by transmitting cells within link-level frames. The service discipline does not require per VC queueing, and thus can be implemented using a fast and simple FIFO architecture. Finally, the service discipline is distributed, thus conformance to the end-to-end delay/jitter bounds can be monitored and controlled on a per node basis.
