The invention provides a resource allocation control method, device and system, wherein the method comprises the steps that: a primary base station obtains indication information used for indicating transmitted buffer data; the primary base station obtains the resource state indication information of the primary base station and the resource state indication information of a secondary base station; according to the resource state indication information of the primary base station and the resource state indication information of the secondary base station, the primary base station determines a first physical resource used for processing the buffer data in the primary base station, and a second physical resource used for processing the buffer data in the secondary base station; the primary base station notifies the secondary base station to reserve the second physical resource; therefore, the secondary base station sends a second scheduling command corresponding to the second physical resource to a terminal; and the primary base station sends a first scheduling command corresponding to the first physical resource to the terminal. By means of the resource allocation control method, device and system provided by the invention, the problem that the resource utilization rate is relatively low due to the fact that carrier aggregation is carried out between cells in the related technology can be solved; and thus, the resource utilization rate when carrier aggregation is carried out between the cells is increased.

The invention discloses a method for defending distributed denial of service attack of an industrial network system, and belongs to the technical field of network security defense. According to the method, deep learning and software defined network technologies are fused to construct an industrial network for preventing DDoS attacks. The deep learning technology for attack detection has the characteristics of flexibility and accuracy, and the SDN realizes the overall network management and flow control of the industrial network. According to the invention, a deep learning classification algorithm is constructed based on AC-GAN, the generator can generate data for a specific label, and the discriminator improves the quality of the generated data by reconstructing label information. According to the method, the sensitivity of the model is improved by generating the adversarial attack sample, and the accuracy of detecting the adversarial DDoS attack in the software defined industrial network is improved. According to the method, real-time flow information is extracted and monitored through the SDIN controller, when attack flow is detected, the system can automatically trigger an attack relieving function, add firewall rules and issue abandoned flow table entry strategies, and therefore DDoS attacks are relieved in time.
