Communication Protocols for Real-Time Systems
Communication protocols for real-time systems are crucial for ensuring that data flows quickly and reliably between different components of a distributed system.
- These protocols are designed to meet the strict timing requirements of real-time applications, where delays can lead to failures and significant consequences.
- They ensure that all parts of the system can exchange information effectively, maintaining system coherence and synchrony even under challenging conditions.
Common communication protocols used in real-time systems include:
- Real-Time Transport Protocol (RTP): It is mainly used for media streaming. RTP provides end-to-end delivery services for data with real-time characteristics.
- Data Distribution Service (DDS): It facilitates scalable, real-time, pub-sub communications. DDS is known for its high performance and robustness in dynamic environments.
- Controller Area Network (CAN): It is used in automotive applications. CAN allows multiple microcontrollers to communicate without a host computer.
- Time-Triggered Protocol (TTP): It is designed for highly reliable systems requiring fault-tolerance. TTP schedules communication in a time-triggered way to avoid data collisions.
Distributed Real-Time Systems
Distributed real-time systems are networks of computers that coordinate to perform tasks instantly. These systems respond to inputs without delay, which is crucial for many modern applications. They manage data and processes across various locations in a synchronized manner. Industries like manufacturing, healthcare, and transportation depend on these systems.
