Virtual network mapping method and system

Abstract

An embodiment of the invention provides a virtual network mapping method and system. The method comprises the following steps: a virtual network mapping request is received, and an importance level of the virtual network mapping request is determined; based on a network topology of a target physical network which is requested to be mapped by the virtual network mapping request, initial backup capability of physical nodes covered by the network topology is calculated; based on the initial backup capability, the level of importance and a preset mapping table, a virtual network corresponding to the virtual network mapping request is mapped. Via application of the virtual network mapping method and system, a virtual network reception rate can be improved while reliability and high efficiency of virtual network mapping are guaranteed.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a virtual network mapping method and system. Background technique [0002] In the prior art, in order to deal with the rigidity of the current Internet network, a network virtualization technology is proposed: the virtual network is mapped on the physical facility network, and the terminal user access can be realized through multiple virtual networks mapped on the same physical facility network. It can meet the needs of network services and adjust the allocation of physical resources, which effectively solves the problem of the rigidity of the current Internet network. [0003] However, when the physical facility network fails or its performance cracks, it will affect the virtual network it carries, and may cause service interruption on the virtual network it carries. The provider pays the corresponding compensation; the service provider will also suffer economic ...

[0003] However, when the physical facility network fails or its performance cracks, it will affect the virtual network it carries, and may cause service interruption on the virtual network it carries. The provider pays the corresponding compensation; the service provider will also suffer economic losses due to poor service experience

In terms of virtual network mapping schemes to deal with possible physical facility failures, most of the existing schemes allocate a working physical resource to it when accepting a virtual network request, and also allocate a backup physical resource to it. Improving the reliability and efficiency of the virtual network does not consider improving the acceptance rate of the virtual network
