Abstract: A storage node cluster access method includes that a tenant inputs an identifier of an application of the tenant and an identifier of a compute node of the tenant into a binding interface provided by the cloud management platform. Next, the cloud management platform creates a binding relationship among the identifier of the application, the identifier of the compute node, and an identifier of storage space serving the application, and enables the compute node to run the application. Then, the cloud management platform deploys the binding relationship in a proxy node. Subsequently, when receiving an access request from the compute node, the proxy node verifies the access request based on the binding relationship. If information carried in the access request conforms to the binding relationship, the proxy node creates the storage space in a storage node cluster or completes data processing in the storage space.

Abstract: A method of forming a convex hull encoding method is provided. The method includes the step of providing a source video clip; splitting the source video clip by a video splitter with a similar scene; slicing each video shots to a preset length video shots; providing down-sampling process, encoding process, decoding process and up-sampling process to obtain the analysis video shots; calculating a quality index between the video shots and the analysis video shots to obtain quality metrics; selecting convex hull points and calculating slopes between the convex hull points; picking operation points with similar slopes to form operation point series and predicting quantizer parameters; encoding the source video clip by the quantization parameters and the corresponding resolutions to obtain a compressed video.
