THE VALIDATION AND INTEGRATION OF THE TRIBUNE TEST-BED

The RACE project TRIBUNE is focused on a number of issues pertaining t o the introduction of the Integrated Broadband Communication. The proj ect has implemented a broadband test-bed with a fully standardized Bro adband User Network Interface (B-UNI) according to the latest ITU-T re commendations. A lot of effort was therefore spent on the specificatio n, implementation and verification of the B-UNI and the integration of the test-bed. This paper is intended to focus on the evaluation of th e innovative methods used and experience gained during the three year period of specification, implementation and verification. In this pape r we will start with focusing on the specification of the B-UNI. Parti cularly the decision to use formal specification languages (-SDL'88) w ill be evaluated. The actual implementation of the B-UNI is discussed in the second past, specially the experience and result of the use of automatic code generation modules. We will elaborate on how the verifi cation of the implementation of the B-UNI was managed in the third par t of this document. Specially the use of the Ferry Clip method and the automatic generation of test suites will be focused upon. Finally, we will show that the taken steps in the previous phases have led to rel atively short and easy integration phase of a complex test-bed around a B-UNI.
