4.2. Methodology¶

4.2.1. Abstract¶

This chapter describes the methodology/overview of SampleVNF project from the perspective of a VNF and NFVI Characterization

4.2.2. Overview¶

This project provides a placeholder for various sample VNF (Virtual Network Function (VNF)) development which includes example reference architecture and optimization methods related to VNF/Network service for high performance VNFs.

The sample VNFs are Open Source approximations* of Telco grade VNF using optimized VNF + NFVi Infrastructure libraries, with Performance Characterization of Sample† Traffic Flows. • * Not a commercial product. Encourage the community to contribute and close the feature gaps. • † No Vendor/Proprietary Workloads

4.2.3. ETSI-NFV¶

SampleVNF Test Infrastructure (NSB (Yardstick_NSB))in yardstick helps to facilitate consistent/repeatable methodologies for characterizing & validating the sample VNFs (VNF) through OPEN SOURCE VNF approximations.

Network Service Benchmarking in yardstick framework follows ETSI GS NFV-TST001 to verify/characterize both NFVI & VNF

The document ETSI GS NFV-TST001, “Pre-deployment Testing; Report on Validation of NFV Environments and Services”, recommends methods for pre-deployment testing of the functional components of an NFV environment.

The SampleVNF project implements the methodology described in chapter 13 of Yardstick_NSB, “Pre-deployment validation of NFV infrastructure”.

The methodology consists in decomposing the typical VNF work-load performance metrics into a number of characteristics/performance vectors, which each can be represented by distinct test-cases.

4.2.4. Metrics¶

The metrics, as defined by ETSI GS NFV-TST001, are shown in Table1.
