PSAD - A Protocol for Synchronization of Distributed Actions
Real-time systems are present in people’s life and are used in several applications like industrial automation and robot motion control. These applications in distributed systems are challenging due to non-deterministic behavior of system elements and communication channels. This paper proposes a protocol called PSAD to deal with action synchronization through system elements. This protocol is based on services for clock synchronization, reliable group communication and real-time task scheduling. An experimental evaluation using local networks shows that it can be used for synchronized applications that need rates around 10 requests per second and jitter around few tens of milliseconds.
