“…On the basis of ensuring delay, Taubrich et al [15] used Temporal Logic of Actions (TLA) to provide AFDX redundancy management algorithms, which could improve the reliability of AFDX to a certain extent. On this basis, Li et al further proposed two redundancy management schemes applicable to different scenarios [16] , which could further tighten jitter and improve its reliability. The static priority non-preemptive queue scheduling (SPUS) algorithm of the AFDX switch cannot eliminate random jitter in the output packet.…”

Time Sensitive Software Defined Networking (TSSDN) is a new network architecture that combines Time Sensitive Networking TSN and Software Defined Networking SDN with the common advantages of both. In this paper, TSSDN is compared with different airborne networks from different perspectives and time-triggered traffic delay analysis is performed. Finally, it analyzes the advantages of TSSDN in civil aviation in general and the perspective to be improved.

“…However, there is still a potential problem,sequence inversion in redundant channels may lead to redundant transmission failure. Meng deduced and analyzed the variable jitter and delay between consecutive frames as the main factors of this problem through modelling [26], and proposed a method to mitigate its impact.…”

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.

“…NASA's Langley Research Center proposed a solution which added an independent decision module to the IMA system to monitor sharing independence among the applications of avionics resources [7]; The thesis [8] proposed a method for analyzing the impact of interrupt correlation using the AADL model. The thesis [9] inverted the risk of redundant sequences in the cumulative transmission of the AFDX protocol; an analysis was carried out, and a method to mitigate this risk by limiting the transmission length was proposed. Some scholars have shown through research [10] that the traditional safety assessment methods based on the chain-of-events model considering only compo-nent failure are not applicable to IMA, which is a softwareintensive system.…”

The reconfiguration technology, which is the significant feature of the newly designed Integrated Modular Avionics (IMA) system, enables the transfer of avionics functions from the failed module to the residual normal module, thereby enhancing the robustness of the whole system. The basic target of the IMA reconfiguration is to ensure the safe flight and correct execution of the mission. To solve the problem of lack of effective management mechanism for the IMA system development and safety assessment, a safety analysis method based on STAMP/STPA and UPPAAL for IMA reconfiguration is proposed. The method focuses mainly on system characteristics and multiparty interactions. On the basis of this approach, some studies and analyses have been carried out. Firstly, the STAMP/STPA principle is studied and used to identify unsafe control actions in the reconfiguration process. Secondly, a formal model of IMA reconfiguration is developed using UPPAAL. Finally, the accessibility analysis of the formal model is used to analyze UCAs and the corresponding loss scenarios. The method enables a detailed description of the interactions between the components and a rigorous mathematical analysis of the system, thereby diluting the effect of human factors while ensuring the accuracy and reliability of the safety constraints.
