Application prospect of time-sensitive network in airborne communication network

Abstract

TSN (Time Sensitive Network) is a real-time Network communication technology being promoted by the international industry. It has the characteristics of more flexibility and high real-time performance. This paper firstly introduces the background of airborne network and real-time network. Then, TSN and the mainstream airborne communication network technology are compared and analyzed from the aspects of synchronization mechanism, scheduling strategy, redundancy and reliability mechanism. Finally, the prospect of TSN in the field of civil aviation is analyzed in general, which makes the application route of TSN in the airborne communication network more clear.

TSSDN aviation prospect analysis

“…However, in order to further improve the resource utilization efficiency of avionics system and the degree of resource distribution, researchers proposed the distributed integrated modular avionics architecture DIMA, which separated IO and application processing modules on the basis of decentralized placement of general processing resources to improve resource utilization [7,8] . All modules in DIMA architecture are connected and provide high fault tolerance, which puts forward higher requirements for real-time and deterministic airborne network technology [9] , and time-triggered technology begins to enter the research field related to airborne network [10][11][12] . In the general field, timesensitive software-defined network TSSDN, which combines time-triggered technology and software-defined network technology, has strong advantages in real-time and deterministic aspects.…”
