Aiming at the needs of the reconstruction of distributed integrated electronic systems based on time- triggered Ethernet, this paper proposes a static network blueprint reconstruction algorithm for virtual link preconfiguration, and uses the virtual link preconfiguration technology to generate the corresponding static network blueprint according to the system blueprint reconstruction strategy, and combines with the message merging algorithm to optimize message preconfiguration, and validates and analyzes the static network blueprint reconstruction algorithm, builts the omnet++ software modular simulation platform to realize the rapid activation of the preconfigured virtual link when a preset network failure occurred.

After Time-triggered Ethernet migrates faults due to node failure, it is necessary to recalculate and schedule the messages that have been migrated. Because there are messages that have completed initial scheduling in the network, scheduling conflicts may occur in incremental scheduling of newly added backup nodes, resulting in failure of solution. In order to solve this problem, this paper proposes a step-by-step incremental scheduling backtracking algorithm based on impact factor. If the incremental scheduling does not find a feasible solution, the strategy of step-by-step backtracking is adopted. According to the size of the impact factor, the messages on the non fault nodes and the message incremental scheduling planning is carried out together with the existing messages to be scheduled.
