Time-sensitive networking (TSN): A group of IEEE standards that allow Ethernet to be applied for time-sensitive applications having the need of both latency and bandwidth. As a result, the critical aspects are fulfilled. The usage of TSN [28] is in various applications such as audio/video distribution, automotive and industrial. The time synchronization is enabled by IEEE 802.1AS. Hence, the behavior of TSN is determined. IEEE 802.1Qbv is the time-aware scheduling that produces the QoS facility. As a result, the coexistence of high-priority traffic is enabled. TSN can provide low latency. TSN can be used for fronthaul as well as backhaul. A TSN standard IEEE 802.1CM has the specificity toward fronthaul. There are many protocols that can run over the Ethernet without Internet Protocol, such as PROFINET and EtherCAT. 5G is integrated with TSN as TSN is interrelated to URLLC in terms of four components, i.e., latency, resource management, synchronization and reliability.

In order to minimize communication latency and communication jitter, the TSN task group is currently defining another shaper, called the time-aware shaper, which at the time of this writing is currently under standardization as IEEE 802.1Qbv Enhancements for Scheduled Traffic. It aims to translate the time-triggered communication paradigm toward the IEEE 802.1 queue-based traffic-shaping model. As in time-triggered communication, the time-aware shaper needs to address two aspects: first, components that use the time-aware shaper require access to a synchronized timebase, and second, the components need to define a communication schedule. The access to the synchronized timebase is inherently present in an AVB/TSN network through the IEEE 802.1AS clock synchronization standard. Hence, all TSN needs to define is how to link this synchronized time to the execution of the communication schedule. The second aspect, how to generate the communication schedule and how to distribute this information in the system, is still in an early phase of technical discussion. However, it is likely that the distribution of the communication schedule will require modifications of the SRP and/or the use of the IS-IS (Intermediate system to Intermediate system) protocol. An example execution trace of what the time-aware shaper is likely to look like is depicted in Figure 20.8.

The IEEE 802.1 Time-Sensitive Networking (TSN) Task Group and the IETF DetNet Working Group define the TSN standard for Ethernets and the DetNet standard for Layer 3 IP/MPLS networks, respectively. This book focuses on the DetNet technology.

Generally, the electrostatic probe measurement system is based on the Ethernet protocol for data transmission. The data link layer of the standard Ethernet uses the carrier sense multiple access with collision detection protocol, which cannot guarantee data transmission within a certain time. Unlike traditional Ethernet, Time Sensitive Networking (TSN) is a protocol that works on the physical layer and the data link layer. It communicates based on the time division multiplexing method. It has a set of clock synchronization protocols to ensure that the clock accuracy of the entire network reaches the 1- to 2-μs level and can guarantee the synchronization and low jitter of the transmitted data.

In recent and upcoming years, most of the network applications are in need of Ultra Low Latency (ULL) transmissions [1]. Some of the applications are given for reference such as Industrial Internet of Things (IIoT) [2] and tactile Internet [3] whereas the end-to-end latency should be on the order of sub-milliseconds. The most typical application is 5G mobile frounthaul where the latency requirements are based on the support of functionality splits, e.g. 100 μs [4] and 250 μs. The IEEE 802.1 standard designed for Time Sensitive Networking (TSN) [5] provides ULL in link layer. The TSN standardization comprises of different processes like flow management, synchronization, control and integrity.
