Problems solved by technology

[0005] In order to solve the problems that the existing virtual network function deployment method only considers a single resource and cannot take into account other resources when configuring resources, which leads to the overload of server resources and the degradation of the entire network performance and the insufficient balance of node resources and link resources. The present invention provides A Virtual Network Function Deployment Method Applicable to Optimal Configuration of Multi-Dimensional Resources

Abstract

The invention provides a virtual network function deployment method suitable for optimal configuration of multi-dimensional resources. The method includes: Step 1: Obtain the network status, update the available resources of all nodes and the remaining bandwidth of the link; Step 2: When detecting the deployment request of the service function chain, judge whether the network meets the deployment condition; Step 3: Follow the request The sequence constraints of each virtual network function in the virtual network function determine the requested deployable node set; Step 4: Calculate the node resource capability and path resource capability of each deployable node; Step 5: Use the service function chain deployment algorithm based on the Viterbi backtracking method to determine Optimal deployment path; Step 6: Deploy virtual network functions in order of nodes according to the optimal deployment path to form a target service function chain, update the network status, and return to step 1. The present invention can achieve a trade-off between various resources according to their respective usage levels, ensuring the optimization of the overall resource consumption of the network configuration and taking into account the network performance at the same time.

Description

A virtual network function deployment method suitable for optimal configuration of multi-dimensional resources technical field The present invention relates to the technical field of network resource deployment, in particular to a kind of virtual system suitable for optimal configuration of multi-dimensional resources Pseudo-network function deployment method. Background technique [0002] NFV (Network Function Virtualization, Network Function Virtualization) decouples hardware and software, and its main The main idea is to decouple network functions from dedicated hardware, and based on general hardware technology and virtualization technology, the required network Functions run on standard commodity servers, storage, and switches in the form of virtual network function software to It is a closed, private, and single-function dedicated hardware device in the modern network. [0003] In NFV deployments, resource overload and underload may occur. The effect of overload...
