“…Motivated by these Ethernet shortcomings, the Institute of Electronics and Electrical Engineers (IEEE) and the Internet Engineering Task Force (IETF) have proposed new definitions to introduce deterministic network packet flow concepts. The IEEE has pursued the Time Sensitive Networking (TSN) standardization [62] focusing mainly on physical layer (layer one, L1) and link layer (layer two, L2) techniques within the TSN task group in the IEEE 802.1 working group (WG). The IETF has formed the DETerministic NETwork (DETNET) working group focusing on the network layer (L3) and higher layer techniques.…”

Many network applications, e.g., industrial control, demand Ultra-Low Latency (ULL). However, traditional packet networks can only reduce the end-to-end latencies to the order of tens of milliseconds. The IEEE 802.1 Time Sensitive Networking (TSN) standard and related research studies have sought to provide link layer support for ULL networking, while the emerging IETF Deterministic Networking (DetNet) standards seek to provide the complementary network layer ULL support. This article provides an up-to-date comprehensive survey of the IEEE TSN and IETF DetNet standards and the related research studies. The survey of these standards and research studies is organized according to the main categories of flow concept, flow synchronization, flow management, flow control, and flow integrity. ULL networking mechanisms play a critical role in the emerging fifth generation (5G) network access chain from wireless devices via access, backhaul, and core networks. We survey the studies that specifically target the support of ULL in 5G networks, with the main categories of fronthaul, backhaul, and network management. Throughout, we identify the pitfalls and limitations of the existing standards and research studies. This survey can thus serve as a basis for the development of standards enhancements and future ULL research studies that address the identified pitfalls and limitations.

“…The IEEE 802.1 TSN enables transmission of various types of critical data over a bridged Ethernet network. Transmitted data can be of different Quality of Service (QoS) levels, regardless of the low latency end-to-end connectivity provided by the TSN [10].…”

Network softwarization enables the novel concept of Local 5G Operator (L5GO) networks, for deploying localized 5G solutions to serve case and location specific communication needs. This paper proposes a L5GO network architecture for delay critical future telehealth services, considering two use cases on augmented reality assisted and robotic aided surgery. The paper compares the latency performance of the proposed L5GO architecture with a traditional legacy network and a network equipped with Multi-access Edge Computing (MEC). The results highlight the unique advantages of utilizing an L5GO to cater the communication needs of delay critical telehealth, compared to a traditional network.

“…IEEE working group 802.1 has a Time-Sensitive Networking (TSN) working group and standards [34] and considers multiple stream flows and latency that meet control loop frequency requirements. For example, a time-critical flow may have guaranteed time slot assignment, routing rules implemented by a fast programmable logic controller, and priority over other traffic [35].…”

Distributed smart and connected community applications of the present and future will continuously sense perishable data on which they make decisions. We say the data are perishable when they represent information sensed at a past point in time, possibly at a distant part of the distributed application, and for which the ground truth could have since changed. This paper discusses actions the sensing source, the network, and the controller can take to make the best possible decisions given that we know only a delayed version of the truth. Some of these actions to preserve freshness of data are based on known real-time techniques such as Time Sensitive Networking. To these we add Information Theory applied on a message-by-message basis and cross-layer coordination between content and network handling. Both the unexpectedness (surprisal) and timeliness (freshness) properties of perishable information can be encoded using a Shannon information entropy framework. Examples of smart community systems of the future for which these concepts are relevant are given.
