To achieve the real time, low latency and deterministic nature required for Industrial use, many Ethernet protocols use specialized Ethernet Media Access Control (Ethernet MAC). This is achieved using hardware acceleration and special data packaging for high-speed encoding and decoding. As a result, users can choose either hardened ASICs or FPGAs for implementation. Some protocols are not offered in ASICs, such as Powerlink and Sercos III, making FPGAs the only viable solution.
