+The design concepts of modern data acquisition systems share many similar features. Among them are
+high bandwidth data transport, synchronization of front-ends and slow-control. This talk focuses 
+on the achieved synergy in data acquisition networks between several experiments of the FAIR project 
+and beyond. The TrbNet protocol developed for the upgrade of the HADES DAQ system is now also
+employed in various prototype set-ups for detectors of the CBM and PANDA experiments. Additionally,
+a modified implementation of the network is foreseen to be used for time synchronization and fast 
+control system for the full PANDA detector setup.

+The synchronization of all sub-systems on the order of nanoseconds can be achieved by implementing
+message transportation with precisely defined latency. Here, it is vital to fix all delays
+introduced in the data transmission blocks on the transmitter and receiver sides. The length of the
+optical cable between two nodes can be evaluated by measuring the round-trip time of a datagram.
+A precision of few nanoseconds down to 20~ps using the well-established FPGA-based TDC technology
+can be reached.
