The present invention relates to a multi-layer cloud application oriented high-availability virtual network mapping method and apparatus, and belongs to the technical field of multi-layer cloud application. The method provided by the present invention comprises: firstly, acquiring multi-layer application requests sent by a user; secondly, performing, according to a quantity of virtual machines required by each layer, descending sorting on the requests sent by the user; then, allocating virtual machine resources to each layer in a descending order of the quantity of virtual machines required by each layer, which is specifically: firstly calculating a feasible vector Se and a minimum feasible value, as shown in the specification, and a corresponding target vector Pe and a corresponding target value, as shown in the specification, of all allocation solutions according to a tree-shaped topology structure of a current cloud platform for the quantity of virtual machines required by the request of the layer, and then acquiring an optimal allocation solution of each link for the layer; and finally, outputting the optimal allocation solution of the multi-layer application requests of the user. Compared with the prior art, in the resource allocation solution provided by the present invention, both resource utilization and feasibility are considered, and efficiency of a whole system is improved while feasibility is ensured.
Description
technical field [0001] The present invention relates to a virtual network mapping method and device, in particular to a high-availability virtual network mapping method and device for multi-level cloud applications, belonging to the technical field of multi-level cloud applications, and specifically to the fields of virtual network availability and resource utilization . Background technique [0002] In recent years, more and more service providers have migrated their multi-tiered applications to public cloud networks. In the traditional cloud network environment, the cloud provider owns physical equipment and can provide virtual network resources to service providers. After each service provider obtains a separate virtual network resource, it can provide certain services for each user. . Virtual network embedding realizes the mapping from virtual network to real physical network. In order to achieve better application service quality, service providers usually have speci...
