Method and system for allocating virtual network resources in regional faults

Abstract

The present invention provides a method and a system for distributing virtual network resources under a sectional fault. The method for distributing virtual network resources under a sectional fault comprises the following steps: a resource pool and a topology resource of a bottom network are initialized; available resources are determined according to scene resource losses of sectional fault scenes and the topology resource, and the virtual network mapping of the available resources and the resource pool are performed to determine a mapping scheme and a resource pool distribution scheme; resource consumption of the mapping scheme in each sectional fault scene is determined; and a final distribution scheme is determined, wherein the final distribution scheme is a resource pool distribution scheme with respect to a mapping scheme having the minimum resource consumption. According to the method and the system distributing virtual network resources under the sectional fault, when a plurality of sectional faults happen, a final distribution scheme is determined to be a resource pool distribution scheme in a sectional fault scene with respect to a mapping scheme having the minimum resource consumption according to the resource consumption of the mapping scheme in each sectional fault scene, therefore the resource consumption of the backup resources required by the final distribution scheme may be reduced.

Description

technical field [0001] The invention relates to the field of virtual network resource allocation, in particular to a method and system for area fault virtual network resource allocation. Background technique [0002] With the rapid development of the Internet, the scale of network users and business scale continues to expand, and the traditional IP Internet architecture has adapted to the current global expansion of the Internet. As an important means to promote the development and innovation of the current Internet, network virtualization technology supports multiple virtual networks to share physical network resources in isolation from each other, can create virtual networks economically and quickly, and deploy network services on virtual networks according to user needs. An efficient and reliable resource allocation method is one of the key factors for the development of network virtualization technology. [0003] Virtual network mapping efficiently allocates physical re...
