A network security management method is provided. In the method, configuration data that includes at least one access control policy for a network asset of a target cloud tenant is received. The network asset includes a private network, a subnet of the private network, and a cloud instance of the subnet. A network management and control unit and an access control policy set corresponding to the network management and control unit are determined according to the configuration data. The network management and control unit includes one or more of a private network-level management and control unit, a subnet-level management and control unit, and an instance-level management and control unit. The access control policy set of the network management and control unit is transmitted to the cloud instance that is associated with the network management and control unit to manage network traffic of the cloud instance.

The present disclosure provides a coordinated multiple access method for multi-cell ground-to-air data transmission, and belongs to the technical field of wireless communication. The method comprises the following steps: S, constructing a model of a coordinated multiple access system for multi-cell ground-to-air data transmission; S, calculating a transmission rate of an aircraft, and constructing a multi-cell airspace and power domain resource allocation optimization problem by taking maximizing a system transmission rate as an optimization objective; S, constructing a Markov decision process model; S, solving the optimization problem using a multi-agent deep reinforcement learning algorithm. The system transmission rate is maximized under the condition that the aircraft can decode the signal correctly and satisfy the constraint of minimum transmission rate, thereby realizing ground-to-air high-speed data transmission. The present disclosure adopts the coordinated multiple access method for multi-cell ground-to-air data transmission, which can realize fast online decision, satisfying the requirements of ground-to-air high-speed data transmission in the high dynamic flight scenario of the aircraft.

The present invention relates to a gasification burner comprising a main burner, N-stage sub-burners arranged on the inner side of the main burner, where N is an integer greater than or equal to 1, the main burner and each stage of the sub-burners have independent fuel channels and oxidant channels respectively, the main burner and each stage of the sub-burners are arranged in a coaxial sleeves from outside to inside; the inner diameter of the main burner is larger than the outer diameter of the first stage of the sub-burners, and the inner diameter of each stage of the sub-burners is larger than the outer diameter of its next stage of the sub-burners; the gasification burner can ensure fuels and oxidants to be mixed fully and evenly in limited reaction space and residence time, accelerate combustion reaction rate, thereby improving fuel conversion rate and gasification performance; meanwhile, it can flexibly adjust flame shape without reducing the load of gasifier furnace by adjusting the load of the main burner and each stage of the sub-burners, thereby effectively avoiding overheating of the gasifier furnace to meet different production load requirements of project sites.
