Development of Emulators and Simulators

Objective

. To identify the areas of the IBC in which the application of emulation/simulation will have an impact.
. To cater for the requirements of the telecommunication management network (TMN) area for emulators and simulators.
. To identify other areas in RACE which could need such systems and cater for their requirements.
. To develop suitable emulation/simulation systems to support the prototyping and testing of selected RACE projects.
The project identifies needs for the application of emulation/simulation through cooperation with projects undertaking systems design. The architecture of a generic emulation/simulation system has now been defined.

The identification of integated broadband communications (IBC) areas which need emulation/simulation and a review of relevant existing techniques, methods and tools have been carried out. Work has started for the production of recommendations on the use of emulation/simulation (E/S) in the testing of IBC.

A general architecture of a parallel high performance transputer based system has been defined. A number of prototype systems based on state of the art, high performance, transputer arrays has been produced. MIME has defined the platform for the development of suitable emulator/simulator hybrid (ESH) systems based on de facto standards such as UNIX, X-Windows transmission control protocol/interface protocol (TCP/IP).
Technical Approach

The project identifies needs for the application of emulation/simulation through cooperation with projects undertaking systems design. The architecture of a generic emulation/simulation system has now been defined. A review of available techniques will indicate those applicable to general and specific problems; the specific needs of the TMN will be used as a starting point for this.

Prototypes for ATM network emulators/simulators will be developed, incorporating important functions of the IBC as required by selected projects. These will be used to support the testing of TMN prototypes. With suitable adaptation, the systems will also support the testing of prototypes from other areas of RACE, such as the Verification and CPN areas. Continuous contacts with other interested RACE projects will lead to a revision of the emulation/simulation architecture used by the project.

Key Issues
The project addresses various ATM network issues in order to develop high performance emulation/ simulation systems. The development of common interfaces with selected RACE projects will also be addressed.

Achievements
The identification of IBC areas which need emulation/simulation and a review of relevant existing techniques, methods and tools have been carried out. Work has started for the production of recommendations on the use of E/S in the testing of IBC.

Following the first year of work, the consortium was in a position to offer for assessment a preliminary view of a proposed emulator/simulator hybrid system (ES).

A review of all RACE projects led MIME to establish close cooperation with a number of RACE projects (R1005, R1082, and R1087).

A general architecture of a parallel high performance transputer based system has been defined. A number of prototype systems based on state of the art, high performance, transputer arrays has been produced. MIME has defined the platform for the development of suitable ESH systems based on de-facto standards such as UNIX, X-Windows, and TCP/IP.

The work has so far resulted in eleven published papers in international forums.

Expected Impact
Availability of emulators/simulators of IBC elements will promote validation techniques for the development of IBC components. In addition, an early availability of emulators/simulators of IBC elements will support the testing of prototypes in RACE projects. MIME is the only RACE project having as its primary goal, to produce ATM based simulators essential for the testing of conformance and performance of networks.
