Proof-by-instance is a technique that ensures the correctness of the results of a computation rather than proving correct the tool carrying out the computation. We report here on the application of this idea to check the computations relevant for analyzing time bounds for AFDX networks. We have demonstrated the feasibility of the approach by applying a proof-of-concept implementation to an AFDX network of realistic size, and we outline the roadmap towards a mature industrial toolset. This approach should lead to a reduction of the time and cost of developing analysis tools used in the design of embedded networks where certification is mandatory.
