EPICS

'EPICS' is a software infrastructure for building distributed control systems to operate devices such as particle accelerators, large experiments and major telescopes. These systems comprise tens or hundreds of computers, networked together so they can communicate and provide control and feedback of the various parts from a control room, or remotely over the Internet.

EPICS uses Client/Server and Publish/Subscribe techniques to communicate between the various computers. Most servers (called Input/Output Controllers or IOCs) perform real-world I/O and local control tasks, and publish this information to clients using the Channel Access (CA) network protocol. CA is specially designed for the kind of high bandwidth, soft real-time networking applications that EPICS is used for, and is one reason why it can be used to build a control system comprising hundreds of computers.
