Time Sensitive Networking
A time-sensitive network (TSN) is a set of Ethernet standards that will allow time-synchronized low latency streaming services through 802 networks. TSN focuses on creating a convergence between information technology (IT) and industrial operational technology (OT) by extending and adapting existing Ethernet standards. It adds the concept of time to networks so that messages can be delivered within a specific time frame.
TSN technology aims to standardize features on OSI-Layer 2 in order that different protocols can share the same infrastructure.
TSN as a communication system can achieve its full potential. The three basic components are:
1. Time synchronization: All devices that are participating in real-time communication need to have a common understanding of time
2. Scheduling and traffic shaping: All devices that are participating in real-time communication adhere to the same rules in processing and forwarding communication packets
3. Selection of communication paths, path reservations and fault-tolerance: All devices that are participating in real-time communication adhere to the same rules in selecting communication paths and in reserving bandwidth and time slots, possibly utilizing more than one simultaneous path to achieve fault-tolerance
