TCP/IP Communication for Real-Time and Embedded Systems

Many embedded systems in industrial automation, machinery, robotics, and other industries communicate data via Ethernet or via a real-time Fieldbus interface such as PROFIBUS or EtherCAT. Often, the embedded system is part of a network that includes sensors or other computers that provide data via TCP/IP. TCP/IP does not lend itself to real-time operation because it is a connection-based protocol that uses a client/server model in which data is retrieved via a series of requests and responses.
