Abstract

Abstract:

Time sensitive networking (TSN) is a set of standards developed on the basis of audio video bridging (AVB). It has a promising future in the Industrial Internet of Things and vehicle-mounted multimedia, with such advantages as high bandwidth, interoperability and low cost. In this paper, the TSN protocol stack is described and key technologies of network operation are summarized, including time synchronization, scheduling and flow shaping, flow management and fault tolerant mechanism. The TSN network model is then established. Its performance is illustrated to show how the frame priority works and also show the influence of IEEE802.1Qbv time-aware shaper and IEEE802.1Qbu frame preemption on network and time-sensitive data. Finally, we briefly discuss the challenges faced by TSN and the focus of future research.

Key words: TSN, AVB, the industrial internet of things (IIoT)
