TSN is an attractive solution for latency-critical frame transmission built upon IEEE 802 architecture. Traffic scheduling and shaping in TSN aim to achieve bounded low latency and zero congestion loss. However, the most widespread solution (i.e. Time-Aware Shaper) requires a networkwide precision clock reference and only targets on cyclical traffic flows. This paper focuses on the performance evaluation of the ATS, which applies shaping algorithm to any flows and requires no clock reference. Simulations are proposed for evaluation and comparison. Metrics including end-to-end delay, buffer usage and frame loss rate are collected to assess the shaping performance. Results show that ATS achieves effective traffic shaping and switching without synchronous mechanisms, while there is an evident trade-off for using these specific algorithms.

“…As alternative to CBS and TAS shaping, a preshaping approach at the senders has been explored in [166]. A complementary analysis of the ATS shaper has bee conducted in [167]. Pre-shaping has been found to be effective for a low number of hops.…”

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.

“…In addition to the shapers described above, other traffic control mechanisms including asynchronous traffic scheduling algorithm such as UBS [84] and ATS [85], [86], preshaping [87] and frame preemption [88], [89], [134] are analyzed, focusing on the worst-case performance such as end-to-end delay and jitter of critical traffic.…”

The automotive E/E architecture has undergone a paradigm shift in the past century. Particularly, the new requirements of automated driving are severely challenging the existing architecture, which has led to ongoing revolutionary innovation in E/E architecture. In this paper, we reviewed the evolution of E/E architecture and outlined the requirements-driven developments. We illustrated the stateof-the-art E/E architecture, including network topology, standards, simulator and software platform. We also discussed the next generation of E/E architecture from the perspective of different OEMs and suppliers. The analysis shows that software-defined, hierarchical, reconfigurable and customized E/E architecture is universally accepted. Furthermore, the automotive industry has been experiencing several transitions related to OEMs and suppliers. With the emergence and maturation of automated driving, we analyzed the new requirements on E/E architecture and proposed prospective development trends.
