N2 - Distributed Integrated Modular Avionics (DIMA) develops from Integrated Modular Avionics (IMA) and enables distributed integration of multiple sub-function areas through Time-Triggered Ethernet (TTE). End-to-end delay analysis for Time-Triggered (TT) and Rate-Constrained (RC) traffic with comprehensive consideration of processing partitions and communication network is necessary to ensure the implementation of complicated functions in DIMA systems. This paper constructs a general DIMA system model embedded with hybrid partition-and network-level scheduling design, analyzes the complete transmission of TT and RC traffic from producer partitions to consumer partitions, and proposes an improved analysis approach based on network calculus. Experimental results present that the partition-level end-to-end delay of TT traffic is significantly optimized by 87.4% compared to traditional separated network scheduling design and the worst-case end-to-end delay of RC traffic at the network level is also optimized by 27.4% compared to traditional analysis approach.
