QualiTest NFV Validation Process
QualiTest aims to create a unified end-to-end approach to service assurance and network performance
NFV Management Orchestration Infrastructure Migration
QualiTest NFV validation process
Assure full compliance to ETSI ISG Standards.
•Define NFV Testing process
•Test Requirements•NFV Test Environment
•Risk Assessment•Roles and Responsibilities
•Team Skills and Training
•Test Inputs / Basis
Assure full compliance to NFV requirements for any network equipment provider and streamline the ability of vendors and users to be able to implement compatible NFV solutions.
Test Environment: simulation tools, network analytics, QoS and QoE probes.Automated Certification Process for each VNF before it is introduced to the network
Test management and Orchestration prior to VNF migration, including each component (e.g. Orchestrator, Vnfm, VIM).
Test the VNF architecture and implementation to assure smooth transition.

NFV/SDN Infrastructure Testing| Verify:
| Functional – Verifying the design| Interoperability – Vendor to Vendor| Performance – Quality of Experience (QOE)| Stability – Guarantee 100% Uptime| Scalability – Vendor vs Organization (size)| Maturity – Is the device “ready to use”
| Conditions:| Real World use cases
vCPE, vIMS, vEPC, Datacenter| Real World Conditions
Multi-tenancies, Multi-Vendor VNF’s| Real World Scenario
Disaster recovery?
| Technologies:| VMWare Platforms or OpenStack
Vanilla vs Vendor Distribution| vSwitch
OpenFlow, VXLAN, BGP-LS, OSPF, PCEP…| VNF’s
Service Chaining
VNF Sample – Security Testing
| Conditions:| Real World Traffic – Your Application Protocols| Real World Attacks – Relevant and New| Real World Scenario – Both above together
| Devices:| vFirewall and vNGFW
(IDS/IPS, Antivirus, filtering…)| DDOS Mitigation | WebApp Firewall| SandBox| VPNs and Tunneling
(IPSec…)
| Verify:| Performance – Quality of Experience (QOE)| Security – Can it protect?| Stability – Guarantee 100% Uptime

Introduction
Summary
| NFV allows agile real time shifting of assets to where they are needed
| Testing, in the new world of (NFV), changes dramatically and becomes a core discipline that is central to the overall goal of pleasing customers in a cost effective way
| The challenge of NFV/SDN is the adjustment of existing technologies or even worth – replacing them! to meet the next generation SW based
