The Scaling Potential of an Optimized TDAQ System

The TDAQ Architecture has been defined and is described in the freshly submitted TDAQ TDR. The architecture described there is based on two possible deployment schemes for the Readout system and leaves a small number of fine-tuning parameters inherent to the architecture open for settlement in the post TDR phase of the project. This note tries to summarize these (few) open issues and shows how these could allow for an almost bottleneck-free architecture for Atlas TDAQ.
