Data acquisition for super colliders

This paper describes simulation studies undertaken at the Superconducting Super Collider, in which the behavior of different Data Collection protocols was investigated as a function of input data variations, bandwidth fluctuations, and input channel correlations. We have sent three kinds of input data through our models of DAQ architectures: fixed size data (every channel carries the same amount of data), exponential distributed data sizes with means coming from physics and detector simulations, and physics data directly. We find differences in the performance, depending on the input data and the DAQ-architecture we study. We conclude that DAQ models should use input data distributions which are as close as possible to reality.
