Schematic of the data flow in AEḡIS. All devices (computers, VME and real-time) are connected to a common LAN subnet and send data to the DAQ PC as GXML Data Objects over TCP or SCP (Secure Copy Protocol). The DAQ computer permanently stores the data on hard-drives as JSON files and ROOTuples. A further backup copy of the data is generated on EOS [51] at CERN. The data can be accessed from outside CERN from EOS or directly from the DAQ computer via a dedicated gateway
