Testing VNF

Virtual Networks Functions (VNF) are being used for increasingly complex network scenarios, involving multi-vendor products and platforms.

A flexible VNF test framework is now seen as essential for ensuring all the different factors are taken into account when testing and certifying VNF. Ideally, this should be done using real-world traffic and repeated regularly to verify consistency following any changes or upgrades to the network.

This White Paper demonstrates how the goals listed above can be achieved using Xena’s stateful traffic generator on configurations orchestrated by CNLabs NFV Test Framework. The open source firewall pfSense is used as the Virtual Network Function

Topics covered in the Testing VNF White Paper:

• Vulcan stateful Test Platform
• CNLabs NFV Test Framework
• pfSense Virtual Firewall
• Baseline Performance
• UDP Throughput
• TCP Connections Per Second
• HTTP Connections Per Second
• Pass-Through SSL Throughput
• Real World Traffic
