Embodiment 1

[0071] See figure 1 As shown, this embodiment provides a method for multi-target matching of network services and virtual resources. The method includes the following steps:

[0072] S1. Perform quantitative analysis on current virtual resources according to preset quantitative indicators, and obtain quantitative evaluation values ​​of virtual resources;

[0073] S2. Based on the demand for virtual resources, combined with quantitative indicators, obtain the network service demand evaluation value;

[0074] S3. Establish a multi-objective matching model that converts multi-objective optimization into single-objective optimization based on the virtual resource quantitative evaluation value and network service demand evaluation value, and obtain the optimal solution based on the multi-objective matching model;

[0075] S4. Deploy network services according to the optimal solution and allocate virtual resources.

[0076] Compared with traditional methods, the efficiency of solving multi-o...

Embodiment 3

[0085] As a better alternative, on the basis of Embodiment 1, the current virtual resources are quantitatively analyzed according to preset quantitative indicators to obtain the virtual resource quantitative evaluation values. The specific process is:

[0086] Deploy a virtualization engine on the server's operating system, build virtual machines based on virtual resources, and perform quantitative analysis of current virtual resources in accordance with instantiation time, memory, hard disk, network bandwidth, latency, security, and energy consumption;

[0087] Among them, the instantiation time is evaluated according to the server CPU frequency, the number of cores, and the virtualization engine, and the instantiation time evaluation value corresponding to each virtual machine is obtained;

[0088] Evaluate the memory on the virtual machine to obtain the memory capacity evaluation value;

[0089] Evaluate the storage resources attached to the virtual machine to obtain the hard disk c...

Abstract

The invention discloses a network service and virtual resource multi-target matching method and system, which relate to the field of communication technology. The method comprises the following steps:quantitatively analyzing the current virtual resource according to a preset quantized index, and obtaining a quantitatively evaluated value of the virtual resources; based on the demand for virtual resources, according to quantitative indicators, obtaining the network service demand evaluation value; according to the quantitative evaluation value of virtual resources and the evaluation value of network service demand, establishing a multi-target matching model to transform multi-target optimization into single-target optimization, and obtaining the optimal solution based on the multi-target matching model; and according to the optimal solution, deploying network services and allocating the virtual resources. The invention can simultaneously carry out optimization treatment on a pluralityof interacting targets, thereby rapidly obtaining an optimal solution or an approximate optimal solution.

Description

Technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for multi-target matching of network services and virtual resources. Background technique [0002] The network function virtualization platform arranges the virtual network function VNF (Virtualized Network Function), constructs a TOSCA template file (Topology and Orchestration Specification for CloudApplication Template), and then submits it to the virtualized infrastructure management platform to allocate a virtual machine VM (VirtualMachine) for execution Specific virtual network functions. Because the network function virtualization orchestrator NFVO (Network Function Virtualization Orchestrator) will correspond to multiple virtual infrastructure design management implements VIM (Virtualized Infrastructure Manager), how to efficiently and reasonably select virtual machines from multiple virtual infrastructure managers to execute specific The virtual net...
