A method for mapping a virtual network

Abstract

A method for mapping a virtual network is provided. The method calculates the metric value of the virtual node according to the CPU requirement of the virtual node and the link bandwidth of the adjacent link, and calculates the metric value of the underlying node according to the CPU resource and the reliability metric of the underlying node and the link bandwidth of the adjacent link. Based on the metrics of the virtual node and the bottom node, the virtual node of the virtual network is mapped to the bottom node of the bottom network, and the neighboring links of the virtual node are mappedto the neighboring links of the mapped bottom node. When the neighboring link bandwidth of the mapped underlying node satisfies the requirements of the neighboring links of the virtual node, virtualization of the underlying network is performed, binding with the virtual network with a more stable way of communication is realized to achieve networking functions, and the underlying network is virtualized through the topology of the virtual network mapping to the underlying network, to achieve the flexible configuration of the underlying network resources, and effectively improve the utilizationof resources.

Description

technical field [0001] The invention relates to the field of underlying network virtualization, in particular to a virtual network mapping method. Background technique [0002] As an emerging technology, network virtualization can implement multiple completely different virtual networks in one or more physical networks through mechanisms such as abstraction, distribution, and isolation. Network virtualization can decouple the underlying infrastructure from the virtual network and allow sharing of virtualized resources. [0003] However, in the process of mapping the virtual network to the underlying network in the prior art, the problem of communication obstruction due to the aging or failure of the underlying network nodes is likely to occur, which brings inconvenience to users. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a virtual network mapping method to solve the problem of communication obstruction caused by...
