ATM Specific Measurement Equipment

Objective

This project studies aspects of the measurement and verification technologies required to support the introduction of asynchronous transfer mode (ATM) technology to IBC networks.

A set of measurement and verification equipment will be specified, consisting of: ATM traffic generator (ATG), ATM traffic analyser (ATA), equipment controller, providing functions such as measurement of cell loss, cell delay and cell delay variation. The project will undertake an investigation of the requirement for and possible realisation of, traffic and terminal emulation. A single prototype variant will be realised for each of these equipments.

The project also aims to coordination the use of this equipment in the integration and verification stages of the related system projects (R1012, R1014, R1022).
This project studies aspects of the measurement and verification technologies required to support the introduction of asynchronous transfer mode (ATM) technology to integrated broadband communications (IBC) networks.

A set of requirements and measurement methods based on a unified testing strategy has been produced. Extensive studies on traffic simulation have been carried out resulting in a highly flexible traffic model for the ATM traffic generator. The detailed functional specification of the test tool based on structured analysis methods has been transformed into a modular implementation concept based on the VXI bus. The implementation of basic modules for ATM traffic analyser and ATM traffic generator has started.
Technical Approach

Based on contributions from cooperating ATM projects (eg R1012, R1014, R1022), consensus has been obtained on the requirements for the test equipment. Specification and implementation of the PARASOL test tools have been strongly supported by the use of structured techniques for system analysis and design.

Key Issues
. Development of measurement methods.
. Specification of test equipment for ATM.
. Implementation of prototypes.

Achievements
A set of requirements and measurement methods based on a unified testing strategy has been produced with the projects R1012, R1014 and R1022.

Extensive studies on traffic simulation have been carried out resulting in a highly flexible traffic model for the ATM traffic generator.

The detailed functional specification of the test tool based on structured analysis methods has been transformed into a modular implementation concept based on the VXI bus.

The implementation of basic modules for ATM traffic analyser and ATM traffic generator has started.

Information exchange within the test environment is discussed with other verification projects in order to reach consensus on common solutions for communication protocols.

The work has so far resulted in twelve publications.

Expected Impact
The results are important for integration tests in the demonstrator projects. The common requirements for testing will also have a harmonising effect on the partner projects regarding interfaces and test access points.

The project is contributing to CFSs on network performance and QOS monitoring.
