Research on complex network consistency performance evaluation based on block matching

During the process of avionics system design and deployment based on avionics full duplex switched Ethernet （AFDX）, the network performance evaluation and optimization is the key to the system functionality verification and certification. The network performance evaluation indicator system is established based on network simulation and network calculus, and the overall evaluation method on real- time guaranteeing capability on the basis of network delay rate category is proposed. Then the distribution condition of network communication task delay rate has been effectively summarized; at the same time, network performance consistency evaluation method is proposed according to density distribution, thus the consistency degree evaluation on network simulation and network calculation is acquired.
