An architecture for QoS analysis and experimentation

We have prototyped and have begun to experiment with an extremely flexible ATM cell store. The cell store accommodates 16 K ATM cells and allows complete software control of the buffer management strategy. The prototype was designed to serve as an output port in an experimental ATM switch, but has also been used as a stand-alone component in several research ATM networks. It is envisioned that the cell store will aid in the realization of queueing strategies capable of supporting emerging ATM and IP service models. This paper describes the motivation, background, detailed design, and an application of the ATM cell store.
