Abstract
A distributed system with an architecture based on synchronized clocks that provides accurate coordination of control functions. The distributed system includes a set of nodes coupled to a communication link. Each node has a clock which holds a real-world time. The nodes participate in a synchronization protocol on the communication link for synchronizing the real-world time in each clock. The architecture of the distributed system is such that the synchronization of control functionality in the distributed system is based upon the real-world time in the clocks. A variety of examples of applications for this architecture are set forth.
