Time-sensitive networking (TSN) is an Ethernet extension defined by the Institute of Electrical and Electronic Engineers (IEEE) designed to make Ethernet-based networks more deterministic. Industries like automotive, industrial and performance audio use real-time communication with multiple network devices and will benefit from the TSN standard.
The consumer and enterprise world of Ethernet and wireless Ethernet communication is bandwidth oriented. For example, while browsing the Internet you accept a varying amount of delay before video playback starts. Although there is a preference for quick interaction, for the average user it is acceptable if one out of 100 clicks perform an order of magnitude worse. However, if a video is bad quality or even halted the typical consumer will be frustrated.
Even infrequent delays are unacceptable in control systems such as those inside automobiles, production lines or concert halls. The most important aspects for these systems are latency and jitter or variation in the latency of control data through the network. The maximum time a packet takes to reach the destination in the system defines the communication cycle or control frequency in the network.
