The present application relates to the field of communication technology, and more particularly to a kind of northbound interface command processing method and system, method includes: through user service and upper system docking, receive the northbound command issued by upper system, parse northbound command and convert into uniform northbound message, then according to the mapping relationship table of equipment network element and service, uniform northbound message is sent to the service corresponding to equipment network element;Through service, uniform northbound message is processed, the conversion of service data is carried out and is issued to equipment network element, and the decomposition and reorganization of service flow are carried out and are sent to equipment network element and execute.The user side and service side function of northbound service are separated in the present application, different types of northbound interface service reuse same service, reduce the cost of opening maintenance and deployment, can make network management system in high concurrency and high throughput, with higher reliability, can reduce the node congestion phenomenon caused by single user or equipment failure.

The invention discloses a load balancer source address conversion control method based on OpenStack Octavia and an SDN (Software Defined Network) technology. The load balancer source address conversion control method comprises the following steps of: configuring a fail provider = sdndriver in a configuration file of an octaviaapi service of the OpenStack Octavia, wherein the fail provider = sdndriver; the method comprises the following steps of: introducing an enable snat parameter into OpenStack Octavia; packaging each northbound interface of the SDN controller by using an sdndriver to carry out calling; the method comprises the following steps: analyzing an enable snat parameter sent by an sdndriver of OpenStack Octavia through a northbound interface of an SDN controller, selecting a southbound interface protocol according to a model of a load balancer, and issuing configuration for enabling or disabling source address translation to a monitor instance of the load balancer, thereby realizing accurate enabling or disabling of source address translation according to a monitor dimension on the premise of being compatible with an OpenStack Octavia native function.

The application relates to a management method and device of a server GPU device, and the method comprises the following steps: after the server is started, a basic input / output system (BIOS) writes GPU static asset information into a H2B PCIE shared memory; a baseboard management controller (BMC) obtains the GPU static asset information and extended static asset information of the GPU device through the H2B PCIE shared memory, and polls each GPU device; if a remote client initiates an information acquisition request of the GPU device, a northbound interface of the server obtains and feeds back the GPU device information through a callback function. The BIOS directly preferentially transmits the GPU device information to a GPU device information region shared memory which is predefined with the BMC in a starting stage, so that the time from the starting of the BIOS to the obtaining of the GPU device basic information by the BMC is shortened.
