Performance Analysis of Critical Traffic of Airborne Integration TTE Network

Abstract

With the deep integration and intelligence of air-borne electronic system, airborne network gradually tends to integration. Integration Time-Triggered Ethernet (TTE) contains standard TTE and micro-TTE (µTTE) network, in which the standard TTE network as the backbone network provides a high-precision fault-tolerant clock synchronization mechanism and supports mixed-critical traffic transmission functions. Besides, µTTE network greatly simplifies the design of the standard TTE network, and provides network functions such as clock synchronization and deterministic unconfigured forwarding for simple devices. Integration TTE network is expected to become one of the main solutions of future airborne integration network. In order to better design and apply the integration TTE network, the extended trajectory method is used to analyze the worst-case end-to-end delay of Time-Triggered(TT) and Rate-Constrained (RC) traffic to ensure the quality of service of critical traffic in the integration TTE network. Besides, comparing the worst-case end -to-end delay of R C traffic in the standard TTE network and the integrated TTE network respectively, the results provide the REFERENCES for the design of the integration TTE network.
