With increasing demands of deterministic and real-time communication, network performance analysis is becoming an increasingly important research topic in safety-critical areas, such as aerospace, automotive electronics and so on. Time-triggered Ethernet (TTEthernet) is a novel hybrid network protocol based on the Ethernet standard; it is deterministic, synchronized and congestion-free. TTEthernet with a time-triggered mechanism meets the real-time and reliability requirements of safety-critical applications. Time-triggered (TT) messages perform strict periodic scheduling following the offline schedule tables. Different scheduling strategies have an effect on the performance of TTEthernet. In this paper, a performance analysis framework is designed to analyze the end-to-end delay, backlog bounds and resource utilization of network by real-time calculus. This method can be used as a base for the performance evaluation of TTEthernet scheduling. In addition, this study discusses the impacts of clock synchronization and traffic integration strategies on TT traffic in the network. Finally, a case study is presented to prove the feasibility of the performance analysis framework.

There has been a considerable amount of research in the area of network performance evaluation. However, little of the research is focused on the evaluation of real-time safety-critical WANs, a need that motivated this research. Over the years, networks have been evaluated by different disciplines from different perspectives. Many of these evaluations focus on network technical performance, or an organization's performance when using a network, or individual users' performance when using a network. In this study, network performance was measured using empirical data from an operational WAN and by utilizing well-defined and well-known network performance metrics such as reliability, availability, and response time. In general, increased use of a real-time WAN in this study was associated with negative impacts on WAN performance and increased redundancy was generally associated with positive impacts, allowing greater system usage and higher network workload, as intended. The impacts of increasing redundancy on MTBF were mixed, as were the MTTR impacts; availability values varied considerably by port. The network performance data thus shows mixed empirical results from increases in network usage and redundancy, which highlights the importance of managing and measuring network performance at both the system and the local level.
