On The Way to a Unified Communication Framework

Modern data-acquisition systems in particle physics put high demands on data throughput and tight constraints on trigger accuracy and timing resolution. Several CERN experiments, e.g., ATLAS, COMPASS, CMS, or LHCb [1] implement their DAQ systems with separate high-speed links for data, trigger distribution and control. The underlying topology of separate links connecting the front-end to the FPGA stages and the computer farms at the back-end is the same. This split topology already raises the question why there is no unified communication interface that can handle data, trigger, and control via a single link. Such a channel would reduce the amount of separate links, simplify the DAQ topology, reduce the number of error sources, and reduce development time.
