Problems solved by technology

[0007] However, in the actual cloud environment, there will be VNF co-location interference (Co-located VNF Interference) between co-located VNFs due to factors such as virtualized physical resource sharing and network I / O bandwidth competition, and VNF performance will be significantly degraded as a result.
There have been several studies on optimizing VNF deployment to minimize operating costs, but none of them considered VNF co-location interference

Embodiment Construction

[0072] The following describes the preferred embodiments of the present invention with reference to the accompanying drawings to make the technical content clearer and easier to understand. The present invention can be embodied in many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned herein.

[0073] In the drawings, components with the same structure are denoted by the same numerals, and components with similar structures or functions are denoted by similar numerals. The size and thickness of each component shown in the drawings are shown arbitrarily, and the present invention does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of parts is appropriately exaggerated in some places in the drawings.

[0074] Such as figure 1 As shown, when one or more SFCs need to be deployed, the vertices are first divided in the form of the parent and chi...

Abstract

The invention discloses a VNF placement method for VNF co-location interference perception in an NFV environment, which relates to the field of NFV and includes: preprocessing SFC; inputting VNF, the SFC and data center node graph information; and sorting the SFC in descending order of calorific value Sorting; use collaborative filtering recommendation algorithm to screen nodes, calculate recommended paths, and form a plan set; through VNF co-location interference quantitative calculation mathematical model, sort the interference loss VNF calorific value in ascending order, so as to screen out the VNF calorific value minimum loss plan that meets the user's QoS ; Repeat the above steps until all the SFCs are deployed. The mathematical model transforms the vector representing the sensitivity and degree of sensitivity of physical resources to obtain a quantitative representation of the performance degradation of VNF co-location interference; the present invention selects an appropriate deployment path based on a collaborative filtering recommendation algorithm, and utilizes VNF co-location The interference quantitative calculation model is used for calculation and comparison, which can minimize the loss caused by VNF co-location interference, thereby greatly reducing the total deployment cost of cloud service providers.

Description

technical field [0001] The invention relates to the field of NFV, in particular to a VNF placement method for VNF co-location interference perception in the NFV environment. Background technique [0002] NFV technology, which uses virtualization technology to softwareize traditional network functions, runs on virtual machines of x86 general-purpose servers, realizes proprietary network functions without dedicated servers and dedicated hardware, and enjoys the agility and Elasticity, which can flexibly deploy and easily scale the resources allocated by VNF (Virtual Network Function), which greatly improves resource utilization and reduces costs compared with traditional network services. [0003] The research on NFV optimization in the past five years mainly corresponds to the three stages of NFV: SFC (Service Function Chain) chaining optimization, VNF placement optimization, and NFV runtime scheduling optimization. [0004] VNF placement means that cloud service providers d...
