      abstract     = {The European XFEL beam delivery defines a unique time
                      structure that requires acquiring and processing data in
                      short bursts of up to 2700 images every 100 ms. The 2D pixel
                      detectors being developed produce up to 10 GB/s of 1-Mpixel
                      image data. Efficient handling of this huge data volume
                      requires large network bandwidth and computing capabilities.
                      The architecture of the DAQ system is hierarchical and
                      modular. The DAQ network uses 10 GbE switched links to
                      provide large bandwidth data transport between the front-end
                      interfaces (FEI), data handling PC layer servers, and
                      storage and analysis clusters. Front-end interfaces are
                      required to build images acquired during a burst into pulse
                      ordered image trains and forward them to PC layer farm. The
                      PC layer consists of dedicated high-performance computers
                      for raw data monitoring, processing and filtering, and
                      aggregating data files that are then distributed to on-line
                      storage and data analysis clusters. In this contribution we
                      give an overview of the DAQ system architecture,
                      communication protocols, as well as software stack for data
                      acquisition pre-processing, monitoring, storage and
                      analysis.},
