Virtual network resource allocation method and device, medium and program product

Abstract

The invention provides a virtual network resource allocation method and device, a medium and a program product, and the method comprises the steps: obtaining a virtual network in a network slice environment, reconstructing the current virtual network and a corresponding bottom layer network, and obtaining a virtual network mapping topology after the virtual network and the bottom layer network are reconstructed; minimizing the number of intermediate nodes between each virtual node and a bottom layer node in the virtual network mapping topology to obtain to-be-allocated bottom layer nodes corresponding to the virtual nodes in the virtual network mapping topology; and mapping a virtual link between the to-be-allocated bottom layer node and the corresponding virtual node through a multi-commodity flow algorithm, so that the to-be-allocated bottom layer node provides network resources for the corresponding virtual node. The invention is used for minimizing the total cost and maximizing the total revenue of the underlying network and solving the problem of network resource allocation waste of the underlying network.

Description

technical field [0001] The invention relates to the technical field of resource management of electric power communication networks, in particular to a virtual network resource allocation method, equipment, media and program products. Background technique [0002] The rigidity of the current Internet architecture makes the application of new network technologies more and more difficult. To solve this problem, network virtualization has become a very effective way. In the network virtualization environment (NetworkVirtualization Environment, NVE), the service provider (Service Provider, SP) rents the underlying network (Substrate Network, SN) resources from the underlying facility provider (Infrastructure Provider, InP) Network, VN) provides customized services to end users without requiring a large investment in the underlying infrastructure. One of the most important tasks in network virtualization technology is to efficiently allocate underlying network resources to virt...
