Virtual network mapping method and device

Abstract

The invention belongs to the technical field of network virtualization, and particularly relates to a virtual network mapping method and device. The method comprises the steps of firstly, extracting initial input characteristics of a virtual network request to be mapped and initial input characteristics of a corresponding physical network; inputting the initial input characteristics of the virtualnetwork request to be mapped and the initial input characteristics of the corresponding physical network into the trained virtual network mapping model to obtain a mapping result; and finally, mapping the virtual network request to be mapped to a corresponding physical network according to the mapping result. According to the method, the characteristics of the virtual network request can be accurately captured; and the physical network is dynamically managed and allocated under the condition that the requirement of the virtual network request is met, so that each virtual node of the virtual network request matches a physical node.

Description

technical field [0001] The invention belongs to the technical field of network virtualization, and in particular relates to a virtual network mapping method and device. Background technique [0002] After decades of development, the Internet is no longer a pure connection network, but has gradually transformed into a content-based network. In the case of increasingly insufficient network equipment and network resources, specialized resource protocols are particularly important for diverse needs and service solutions, so it is necessary to make appropriate modifications to the current Internet architecture, but the network is constructed and operated by multiple providers and management, where these stakeholders have multiple competing goals, making modification difficult and network rigidity a problem. [0003] In order to solve the problem of network rigidity, network virtualization technology emerges as the times require. Network virtualization technology decouples netwo...
