“…The latter was driven by the need to reduce the weight of wiring and increase the bandwidth. The 1000BASE-T1 is based on an unshielded single twisted pair at 1 Gbit/s and it was initially targeting automotive [ 28 ], then it also gained high interest in avionics for medium and low DALs, such as the cabin management [ 29 , 30 ].…”

The complexity and costs of the avionics communication architecture are increasing exponentially with the increasing number of embedded computers over the last few decades. To limit the cabling complexity and the deployment costs of such a communication architecture, we specify a new Gigabit multiple-ring Ethernet network, called AeroRing, while meeting the avionics requirements. First, we describe the current Aircraft Data Communication Network (ADCN) to highlight the main characteristics and requirements that have to be fulfilled by our solution. Then, we give an overview of the most relevant solutions to improve ADCN performance and relate them to AeroRing. Afterwards, we detail the specifications and the main Performance Indicators (PIs) of AeroRing. Finally, sensitivity and validation analyses of AeroRing are conducted through a realistic avionics application, regarding the various PIs, in comparison to the backbone network of the ADCN, the Avionics Full DupleX Switched Ethernet (AFDX). The computed AeroRing performance metrics show its ability to guarantee the avionics requirements.

Abstract-Ethernet is a low-cost communication solution offering high transmission speeds. Although its applications extend beyond computer networking, Ethernet is not suitable for realtime and safety-critical systems. To alleviate this, several real-time Ethernet-based communication protocols have been proposed, such as TTEthernet, which is the focus of this paper. TTEthernet is suitable for mixed-criticality systems both in the safety and temporal domain. TTEthernet offers three traffic classes: static timetriggered (TT) traffic, dynamic traffic with bounded transmission rate (called "Rate Constrained", RC), and unbounded dynamic traffic (BE). In this paper we propose a novel worst-case endto-end delay analysis of the RC traffic for TTEthernet systems. The proposed technique considerably reduces the pessimism of the analysis, compared to existing approaches. We have evaluated the new analysis using several test cases.

Abstract-This paper focuses on the optimization of the TTEthernet communication protocol, which offers three traffic classes: time-triggered (TT), sent according to static schedules, rate-constrained (RC) that has bounded end-to-end latency, and best-effort (BE), the classic Ethernet traffic, with no timing guarantees. In our earlier work we have proposed an optimization approach named DOTTS that performs the routing, scheduling and packing / fragmenting of TT and RC messages, such that the TT and RC traffic is schedulable. Although backwards compatibility with classic Ethernet networks is one of TTEthernet's strong points, there is little research on this topic. However, in this paper, we extend our DOTTS optimization approach to optimize TTEthernet networks, such that not only the TT and RC messages are schedulable, but we also maximize the available bandwidth for BE messages. The proposed optimization has been evaluated on a space application case study. I. INTRODUCTIONThe increase in functionality that is implemented as realtime embedded applications, most often on distributed architectures, has resulted also in increased bandwidth require- TTEthernet [9] is a deterministic, synchronized and congestion-free network protocol based on the IEEE 802.3 Ethernet [6] standard and compliant with the ARINC 664p7specification [1]. ARINC 664p7 is a full-duplex Ethernet network, which emulates point-to-point connectivity over the network by defining virtual links, tree structures with one sender and one or several receivers (see Section II). TTEthernet supports applications with mixed-criticality requirements in the temporal domain, providing three types of traffic: static timetriggered (TT) traffic and dynamic traffic, which is further subdivided into Rate Constrained (RC) traffic that has bounded end-to-end latencies, and Best-Effort (BE) traffic, for which no timing guarantees are provided. TT messages are transmitted based on static schedule tables and have the highest priority. RC messages are transmitted if there are no TT messages in transmission, and BE traffic has the lowest priority. TTEthernet is highly suitable for applications of different safety criticality levels, as it offers spatial separation for mixed-criticality messages through the concept of virtual links. TTEthernet is suitable for automotive [12], avionics [15] and space [5] applications.
