Abstract	For new detector and trigger systems to be installed in the ATLAS experiment after LHC Run 2 a new approach will be followed for front-end electronics interfacing. The FELIX (Front-End Link eXchange) system will interface to links connecting to front-end detector and trigger electronics instead of the RODs (ReadOut Drivers) currently used. FELIX will function as a gateway to a commodity switched network built using standard technology (either Ethernet or Infiniband). In the paper the new approach will be described and results of the demonstrator program currently in progress will be presented.
