SWITCHING BLOCK STUDIES, NETWORK PERFORMANCE EVALUATION AND TRAFFIC ENGINEERING FOR ATM

This paper summarizes the work done in RACE project 1022 ''Technology for ATD'' on performance studies of ATM switching block architectures and the studies on network performance within a small ATM network, the so called RACE ATD Technology Testbed (RATT). The aim of the studies was to investigate the behaviour of a typical ATM network under nomina l load. By using the tromboning links in the RATT we were also able to study long distance connections even in the limited size of the RATT network. Special attention has been given to define a traffic scenario which can also be set up for the planned experiments. The goal of the planned experiments is to validate the performance results predicted in our studies.
