Embodiment Construction

[0081] In order to achieve the above object, the present invention adopts the following technical solutions:

[0082] Firstly, a double sharing mechanism based on the backup revenue index is used for reliability deployment. The execution process of the method is as follows: figure 1 Shown:

[0083] ① According to the business requirements of the network, the initial placement of the service function chain is carried out according to the corresponding deployment method;

[0084] ② Next, evaluate the reliability of the service function chain to determine whether the reliability of the service function chain meets the reliability requirements of the business;

[0085]③If it is not satisfied, by calculating the backup revenue index of all virtual network functions in the entire service function chain, select the virtual network function with the largest backup revenue index and the second largest virtual network function, and perform double shared reliability on nodes that meet ...

Abstract

The invention discloses a virtual network function reliability deployment method based on backup revenue and remapping. The method comprises the following steps: firstly, introducing a dual-sharing backup mechanism, wherein the reliability of the service function chain is effectively improved, meanwhile, resource occupation of backup is reduced as much as possible, the resource utilization rate ofthe system is improved; and then providing a reasonable and efficient virtual network function remapping method for the virtual network function which is not subjected to reliability backup in the service function chain. The method provided by the invention is used for solving the problem that the reliability of the service function chain is reduced due to the fact that the virtual network function in the service function chain is subjected to backup recovery after a fault occurs and the reliability of the virtual network function is changed after remapping for the first time.

Description

technical field [0001] The invention relates to a virtual network function reliability deployment method based on backup revenue index and remapping, and belongs to the field of network technology. Background technique [0002] 5G is a new generation of mobile communication system for the development of mobile communication needs after 2020. With the full arrival of 5G networks, network virtualization technology has become one of the key technologies for network service model transformation and the basis for dynamic and elastic deployment of network services. Network function virtualization softwareizes the network functions on the original dedicated hardware, and realizes them by virtual network functions deployed on general-purpose servers. While reducing operating costs and improving the flexibility of network functions, it also leads to the emergence of some new problems. For example, the reliability of network services is affected by network functions, and failures of ...
