“…In TTE based networks, several studies have been carried out to monitor and improve end-to-end delays in TT traffic performance [1] in avionics networks and other fault-tolerant networks. As our focus is integrated avionics module (IMA) or Distributed Avionics Modules (DIMA), In this paper, we look to explore methods for externally synchronizing TTE networks for fault-tolerant applications in avionics and study their impact on quality of service (QoS) focusing on end-to-end latency in the network.…”

“…Although our focus is avionics, we look to explore methods in an externally synchronized TTE network for fault-tolerant applications in avionics to develop and study their impact. Current research focuses on utilising TTE networks based on internal clocks and discusses methods to improve delays in endto-end traffic [1] [6]. Furthermore, a considerable barrier exists when analyzing the TTE network with external clocks being synchronized for TT messages.…”

Significant developments are made in unmanned aerial vehicles (UAVs) and in avionics, where messages sent in the network with critical Time play a vital role. Several studies in Time-Triggered Ethernet have been carried out, but these studies. Still, these improving QoS such as latency in end-to-end delays of an internally synchronized TTE network. However, no one monitors integrated modular avionics. We proposed a framework that enables TTE to be externally synchronized from a GNSS to overcome this problem. We have incorporated our proposed Algorithm in the TTE protocol based on specific parameters and multiple existing algorithms. The proposed Algorithm gives us the ability to control and synchronize the TTE network. Also, we have a developed scenario for analyzing the performance of externally synchronized end-to-end latency of TT messages in a TTE network.We simulated scenarios in our framework and analyzed QoS but, more specifically, the latency that affects the performance of time-triggered messages in externally synchronized TTE networks. The result shows that our proposed framework outperforms existing approaches.
