NFV monitoring and diagnostics

NFV and telco data center infrastructure visibility using Veryx vTAP

Virtual Tap (vTAP) for NFV Visibility

Network Functions Virtualization (NFV) is a network architecture that implements virtualization of network node functions to deliver communication services efficiently.

While this brings in a major shift in manner in which networks will be deployed, service providers need to ensure that their SLA metrics will not be degraded by performance of the data center and cloud infrastructure.

Monitoring virtual environments is more complex than their physical equivalents because NFV servers are expected to contain dozens of service chains and hundreds of network functions.

With Veryx vTAP, complete visibility of VNF traffic is provided and the data that is tapped can be analyzed with Veryx Flow Analyzer and other third-party analyzers.
