Abstract

The disclosed systems and methods are directed to a computer-implemented method for use in designing a service. In at least one embodiment, a method includes designing a service with one or more generic virtual network functions (VNFs), where the generic VNFs are defined independent of vendor sourcing information. One or more trained machine learning (ML) models are used to identify VNFs available from VNF vendors that may source one or more VNFs similar to the generic VNFs. The service is implemented using VNFs provided by one or more VNF vendors, where the VNFs provided by the one or more VNF vendors have network functionality generating similar to the one or generic VNFs.

First claim

What is claimed is:

1. A computer-implemented method for use in designing a service, the method comprising:
designing a service with one or more generic virtual network functions (VNFs), wherein each of the generic VNFs is defined to provide a generic network functionality independent of vendor sourcing information;
using one or more trained machine learning (ML) models to identify available VNFs from VNF vendors that source one or more VNFs to implement the generic network functionality;
determining a similarity score for each implementation of the generic network functionality by a respective one of the available VNFs;
using the similarity score for each implementation of the generic network functionality to select one of the available VNFs to implement the generic network functionality; and
implementing the service using the selected one of the available VNFs to implement the generic network functionality.

2. The computer-implemented method of claim 1 , wherein
the one or more trained ML models include an ML quality model configured to assess a quality of VNFs provided by vendors.

3. The computer-implemented method of claim 2 , wherein the method further comprises:
executing an unsupervised learning operation using raw data relating to past performance of vendors providing VNFs;
clustering and classifying data provided from the unsupervised learning operation to generate a set of training data; and
using the set of training data to train the ML quality model.

4. The computer-implemented method of claim 1 , wherein
the one or more trained ML models include an ML similarity scoring model configured to
identify a degree of similarity between one or more of the generic VNFs and one or more VNFs available from the vendors.

5. The computer-implemented method of claim 4 , wherein
the ML similarity scoring model is trained using data derived from VNF images, VNF descriptions, and taxonomy data available from the vendors; and
wherein training the ML similarity scoring model further includes feature selection and engineering of features derived from the VNF images, VNF descriptions, and taxonomy data.

6. The computer-implement method of claim 5 , wherein
the data derived from feature selection and feature engineering are subject to localities sensitive hashing to train the ML similarity scoring model.

7. The computer-implemented method of claim 1 , wherein
the one or more trained machine learning (ML) models provide VNF and vendor information including one or more VNF vendors, the VNFs available from VNF vendors that source VNFs similar to the generic VNFs, VNF vendor quality metrics, similarity scores comparing vendors sourced VNFs with generic VNFs, and/or taxonomy data for VNFs provided by vendors, and wherein the VNF and vendor information is stored in a smart VNF catalog.

8. A computer system comprising:
one or more information handling systems, wherein the one or more information handling systems include:
a processor;
a data bus coupled to the processor; and
a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus;
wherein the computer program code included in one or more of the information handling systems is executable by the processor of the information handling system so that the information handling system, alone or in combination with other information handling systems, executes operations comprising:
designing a service with one or more generic virtual network functions (VNFs), wherein each of the generic VNFs is defined to provide a generic network functionality independent of vendor sourcing information;
using one or more trained machine learning (ML) models to identify available VNFs from VNF vendors that source one or more VNFs to implement the generic network functionality;
determining a similarity score for each implementation of the generic network functionality by a respective one of the available VNFs;
using the similarity score for each implementation of the generic network functionality to select one of the available VNFs to implement the generic network functionality; and
