Introduction + +The objective of the OPNFV project titled **“Characterise vSwitch Performance for Telco NFV Use Cases”**, is to evaluate a virtual switch to identify its suitability for a Telco Network Function Virtualization (NFV) environment. As well as this, the project aims to identify any gaps or bottlenecks in order to drive architectural changes to improve virtual switch performance and determinism. The purpose of this document is to summarize the results of the tests carried out on the virtual switch in the Network Function Virtualization Infrastructure (NFVI) and, from these results, provide evaluations and recommendations for the virtual switch. Test results will be outlined in [Details of the Level Test Report](#DetailsoftheLevelTestReport), preceded by the [Document Identifier](#DocId), [Scope](#Scope) and [References](#References). + +This document is currently in draft form. + +<a name="DocId"></a> +### 1.1.

Scope + +The scope of this report is to detail the results of the tests that have been performed on the virtual switch.
