With UDP and custom FPGA IP for handling the packets the processing works fine. Network behavior is made easier as the IO board will mostly be used in a dedicated point-to-point Ethernet connection. Our opinion is that Ethernet is easier to analyze using tools such as Wireshark, in addition to being easier to run in a cable between different PCAs. It also allows the IO board to be easily networked for communicating with development tools to reprogram the FPGA memory, debug issues, do testing from a developer machine etc without concern for driver issues on various host operating systems.
