Protocol stack-based telecom emulator

The paper describes the concept and implementation of a telecom emulator that features both reconfigurability and high-speed processing. The emulator can be easily transmuted into any telecom system as a real node. It has two innovative system design concepts. The first is to divide the specification into simplified processes based on the open system interconnection (OSI) reference model. The second is the use of a sophisticated hardmacro and its software-callable driver. We implemented a prototype system called ATTRACTOR and applied it to some telecom applications. The applications were able to be implemented in a short design time and were operated in real computer network environments.
