Synchronize Your Watches: Part II: Special-Purpose Solutions for Distributed Real-Time Control

The ability to carry out coordered activities in distributed applications is currently considered a basic requirement in most industrial scenarios as well as in many areas with demanding real-time constraints, such as modern electric power systems, the automotive/avionic domains, and some types of networked embedded control systems. For this reason, the majority of the networks that were conceived recently for use in these environments provide some means to deal with distributed clock (DC) synchronization.
