The present disclosure relates to a network operation and maintenance technology, and in particular to a system and method for generating network device driver files. One aspect of the present disclosure provides a system for generating network device driver files. The system includes: a network device capability model construction unit, configured to construct a capability model following a standard format on the basis of a capability set acquired from a network device; a driver function interface generation unit, configured to generate, based on the capability model, a driver function interface that can be called by an upper-layer application; and a control message generation unit, configured to receive configuration data from the upper-layer application via the generated driver function interface, and to generate, based on the configuration data, a control message for driving the network device.

Network device driver file generating system, method, device, and medium

The simulation device is provided with a user space and a network adapter. The method comprises: a simulation device obtains a serialization command of a simulation test and configures the serialization command for a plurality of MQTT client instances, controls the plurality of MQTT client instances to package the serialization command by using a simulation protocol stack of a user space so as to obtain a simulation message, transmits the simulation message to a network adapter, and the network adapter sends said message to an MQTT server for simulation testing.

A data transmission method includes: determining, by a regional access device, a message that needs to be transmitted includes M pieces of QoS information; and after the regional access device determines that a device identifier in a first piece of QoS information is consistent with a device identifier of the regional access device, updating a QoS value of the message that needs to be transmitted with a first QoS value in the first piece of QoS information, and forwarding the updated message that needs to be transmitted. The first piece of QoS information is any one of the M pieces of QoS information.

Data transmission method and apparatus

A method for creating a virtual machine and/or a container through a unified resource scheduling coordinator, a unified resource scheduling coordinator, a unified resource scheduling system and a computer storage medium. The method includes: receiving an instruction to create the virtual machine and/or the container, wherein the instruction comprises parameters of the virtual machine and/or the container; selecting a first computing node from physical nodes according to the parameters; transmitting the parameters and information of the first computing node to a virtual machine management module and/or a container management module depending on whether the virtual machine or the container is to be created; receiving resource allocation condition from the virtual machine management module and/or the container management module after creation of the virtual machine and/or the container; notifying the resource allocation condition to the container management module and/or the virtual machine management module after recording of resource change condition.
