“…In [8], the academic version of TTEthernet is introduced to integrate TT and ET traffic together. In [9], an academic version of TTEthernet switch is developed which preempts ET message transmission when a TT message arrives to guarantee a constant transmission delay of TT messages caused by the switch regardless of the load of ET traffic on the network. In [10], a prototypical TTEthernet controller is described and implemented in an FPGA.…”

Abstract. When designing cyber-physical systems (CPS), virtual prototyping can discover potential design flaws at early design stages to reduce the difficulties at the integration stage. CPS are typically complex real-time distributed systems which require networks with deterministic end-to-end latency and bounded jitter. Time-triggered Ethernet (TTEthernet) integrates time-triggered and event-triggered traffic, and has been used in many CPS domains, such as automotive, aerospace, and industrial process control. In this paper, a TTEthernet model in SystemC/TLM is developed to facilitate the design and integration of CPS. The model realizes all the necessary features of TTEthernet, and can be integrated with the hardware platform model for design space exploration. We validate the model by comparing latency and jitter with those obtained using a commercial software-based implementation. We also compare our model with the TTEthernet modeled in OMNeT++ INET framework. Our model provides startup and restart services that are necessary for maintaining synchronized operations in TTEthernet. We evaluate these services and also the efficiency of the simulation.

“…At one extreme (E), scheduling and admission is completely uncontrolled while at the other extreme (A), admission is strictly controlled by assigning periodic access times as done in earlier versions of TTE. Later versions of TTE (B), allow three classes of service enabled by special bridges [8]. Prior work based on QoS information in Ethernet headers can provide some improvement (D), again with appropriate bridges.…”

The problem addressed in this paper is the limitation imposed by network elements, especially Ethernet elements, on the real-time performance of timecritical systems. Most current network elements are concerned only with data integrity, connection, and throughput with no mechanism for enforcing temporal semantics. Existing safety-critical applications and other applications in industry require varying degrees of control over system-wide temporal semantics. In addition, there are emerging commercial applications that require or will benefit from tighter enforcement of temporal semantics in network elements than is currently possible. This paper examines these applications and requirements and suggests possible approaches to imposing temporal semantics on networks. Modelbased design and simulation is used to evaluate the effects of network limitations on time-critical systems.

“…This corresponds to a basic form of time-triggered communication as it is defined by Time-Triggered Ethernet switch. 44 The switch supports time-triggered (according to SAE AS 6802), rate-constrained (AR-INC 664, part 7), and COTS Ethernet (IEEE 802.3) traffic flows. Time triggered domain needs to be shared among all TTEthernet participants and switches.…”

The Quality of Service (QoS) offered by a network is based on criteria such as delay, jitter and message loss. QoS management is crucial to ensure that the network respects the communication constraints defined by the application requirements. The network must dynamically manage QoS according to the evolution of network usage. To control QoS, the network implements mechanisms to schedule and regulate traffic. The main issue is identifying the relationship between these mechanisms and their effects on QoS values. The objective of this paper is to propose a method, based on fuzzy logic, for identifying this relationship and reusing it to dynamically control QoS. This study only focuses on the impact of the Weighted Round Robin (WRR) scheduler on the delay in a switched Ethernet network. The fuzzy controller is implemented in a network simulation tool (Riverbed Modeler) to efficiently manage the delay in the network.
