Example Embodiment
[0036] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.
[0037] figure 1 It is a flowchart of a remapping method based on dynamic changes in virtual network resource requirements according to an embodiment of the present invention. Such as figure 1 As shown, the method shown includes the steps:
[0038] S100: First, a physical network model, a virtual network model, a physical network available resource model, and an original virtual network mapping model need to be established.
[0039] Physical network model: abstract the physical network as a weighted first undirected graph G S =(N S , E S ), where N S Is the collection of all physical nodes, E S It is the collection of all physical links. When describing the resources in the physical network, CPU capacity is used ...
