Method and device for cloud service downlink in edge-cloud computing environment, and equipment

Abstract

The invention discloses a method and device for cloud service downlink in an edge-cloud computing environment, and equipment. The method comprises the following steps: establishing a model of a downlink cloud task of issuing an award R to an edge node i by a cloud node; defining the utility-ui of the edge node i and the utility u0 of the cloud node; establishing a Stackelberg game model for simulating an excitation mechanism; defining a Stackelberg equilibrium SE, an optimal resource strategy ci * and an optimal reward strategy based on the utility ui of the edge node i, the utility u0 of thecloud node and the Stackelberg game model; obtaining an effective algorithm obtained according to the Stackelberg equilibrium SE, the optimal resource strategy ci * and the optimal reward strategy inthe dynamic environment; establishing a model for reconstructing a downlink cloud task according to an effective algorithm; and executing cloud service downlink by utilizing the model for reconstructing the downlink cloud task. According to the method, the cloud nodes and the edge nodes are efficiently stimulated to cooperate, and heterogeneity and resource capacity of the edge nodes are considered, and an actual dynamic environment is supported.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a cloud service downlink method, device and equipment in an edge-cloud computing environment. Background technique [0002] In an edge-cloud computing environment, many cloud providers intend to downlink cloud services to edge nodes in order to provide high-quality services for data-intensive and latency-sensitive applications, but few edge nodes do so without any return. Under the voluntary provision of resources, few edge nodes join the cloud computing environment, and the heterogeneity of resource capacity among edge nodes makes this incentive mechanism more challenging. Contents of the invention [0003] In view of this, the purpose of the present invention is to propose a cloud service downlink method, device and equipment in an edge-cloud computing environment to solve the problem of the lack of edge nodes in the cloud computing environment in the prior art and ...
