NFV reshaping the future of Telco Networks

NFV is rapidly gaining momentum and is transforming the telecom industry in the way new services are developed, deployed and monetized. The NFV model enables the creation of scalable and resilient networks using cloud virtualization techniques. With NFV, virtualized network functions (VNFs) are hosted on commercial off-the-shelf servers and chained to realize game changing services. However, thorough validation of NFV environments is required to break free from the endless PoC cycles and accelerate real world deployments.

The NFV Domains we Validate

vSwitches and NFV Infrastructure

Finger pointing at a device

Validate NFV infrastructure as a blackbox or its individual components such as vSwitches, NICs, and the ability to support various VNFs that execute on NFVI.

Virtual Network

Benchmark individual virtualized network functions (VNFs) for functionality, performance and their support for lifecycle operations.

NFV Orchestration and
E2E services

What to Test


Data plane benchmarking

Benchmark the forwarding and application throughput performance of vSwitches, and VNFs using various traffic mixes and acceleration technologies


VNF control plane validation

Validate control plane functionality and scale of VNFs and ensure compliance to IETF, 3GPP and ETSI NFV requirements


Service chain validation

Test the functionality and performance of NFV service chains and perform bottleneck analysis to identify weak links in the service chain


Compute, memory & storage performance of NFVI

Benchmark the NFV infrastructure and its ability to support the compute, memory and storage performance requirements for all the VNFs


VNF & Network services lifecycle validation

Validate the VNF and Network services lifecycle operations including successful instantiation, time to instantiate, autoscaling and graceful termination


Carrier grade readiness of NFV

Ensure long duration stability of your network. Trigger failures on primary path and measure the time needed to converge traffic and services to backup path
