Service providers seeking to embrace NFV transformation by deploying virtual network functions (VNFs) with little to no disruption to business practices or the customers they serve.


Hybrid networks and VNF management will be challenging

Network Functions Virtualization (NFV) enables service providers to be more efficient and launch services faster than ever. However, the dynamic nature of NFV adds incredible complexity to network management and operations. Compounding the problem is the fact that VNFs do not usually operate in isolation, but rather work alongside existing physical network functions. This hybrid network approach makes assuring the reliability and availability of networks and services more challenging, and even more critical to achieve.

Complete visibility is the key to NFV success

NFV deployment makes perfect sense – it will allow you to simplify your network operations and lower operational costs, but once a service is virtualized, how can you be sure it’s performing as it should?  With a universe of activity out there, you need a seamless view across your virtual and physical networks.  Visibility into VNF performance through packet data analysis of the traffic flowing across your entire network is absolutely critical to successful NFV deployments.

NETSCOUT provides visibility to critical network data in virtual environments

NETSCOUT’s NFV Service Assurance solution helps service providers manage this complex and dynamic environment with correlated, end-to-end, 360° visibility across the entire network.  Our InfiniStream family of products include virtual, COTS-based software and appliance-based instrumentation that provide the same level of visibility within virtualized infrastructures that is already possible in physical environments. NETSCOUT’s patented Adaptive Service Intelligence (ASI) technology efficiently analyzes packet data across the network for the deepest performance insights, to ensure successful NFV deployments. 


NETSCOUT supports OpenStack® + KVM and VMware® Cloud environments, providing visibility to critical network data that is lost when operators virtualize key network functions. This allows administrators to use the full suite of OpenStack and VMware administrative tools to orchestrate the NETSCOUT virtual probes and the VNFs monitored by them.  

Network virtualization implementations vary

We understand that NFV evolution looks different for every service provider. Whether NFV is being implemented to add EPC and IMS network capacity, or to add new services and applications for customers, NETSCOUT delivers the information you need, when you need it, ensuring the best customer experience.  Since 2009, we’ve been helping our customers minimize the disruptions caused by network virtualization.
