After the network is infected by virus, it is necessary to optimize the communication networking of the routing nodes to ensure the stability and robustness of the network communication. A optimal node communication network technology based on VMEbus bus rotation scheduling control after the network invasion is proposed. In combination with embedded control technology, the optimization design of node communication networking control system after network intrusion was done. The man- machine communication module is composed of the serial port, VXI bus and can bus. The clock synchronization technology is used to realized program control of communication node networking and regulation of adaptive networking to make layering grid level scheduling of malicious nodes in the ring buffer RAM. In the design of hardware module, AD sampling filtering circuit, re- set circuit, clock trigger circuit, central control circuit and peripheral interface circuit are designed. In the embedded platform, the software development of the system is carried out. The optimal control of optimal node communication networking selection af- ter network intrusion was realized. The simulation results show that the system can improve the anti-jamming ability of network intrusion, reduce the bit error rate of network data transmission, and guarantee the network security.
