Abstract
In this paper, we formulate the problem of constructing an onboard switched network of minimum complexity required for real-time transmission of periodic messages, as well as propose algorithms for its solution (generating the network structure and system of virtual links). Results of the experimental evaluation of the proposed algorithms for constructing onboard AFDX networks are also presented.

Notes
According to the standard [4], redundancy is achieved by using two independent networks. For each virtual link, the end system sends a data copy to both the networks. In this paper, we analyze data transmission only through one network with the results for the other network being similar.
This constraint stems from the recommendations described in the standard [4].
At this step of the algorithm, it is not required to delete links used in the network with subsequent reconfiguration of virtual routes because the routing procedure takes into account not only the length of the links, but also their involvement in the transmission of the already allocated messages; thus, at each iteration of the procedure, the complexity of the network either does not change or increases only slightly.
