Network functions virtualization (NFV) completely changes how networks are designed, built and managed. It pulls the functions necessary to run networks off of the current proprietary hardware and places it on open-based computer servers that can be deployed where they are needed most. Functions can be deployed and scaled on demand, greatly improving infrastructure utilization and significantly bending the network cost curve growth.
In a virtualized network environment, assurance solutions and processes must transition from traditional, reactive monitoring to proactive, real-time intelligence and analytics, tightly integrated with and coupled to the network and services, as well as orchestration and policy systems. Also, assurance solutions must span multiple services, including Ethernet/IP, video and mobile.
As the statistics suggest, M2M will likely experience rapid growth over the next several years, which makes this is a critical time for test vendors. Obviously, it's impossible for anyone to know for certain how much growth will take place or how many devices ultimately will be connected to the Internet.
While monitoring-system costs have been growing almost linearly with the growth in network traffic, tomorrow's solutions must break this growth curve by leveraging virtual agents for intelligent network probing, coupled with streamlined data collection and storage. As with all network technology transitions, the legacy technology does not disappear for some years and, therefore, assurance solutions and processes must deliver an approach supporting both virtualized and non-virtualized environments, enabling a transition from today's networks to future software-defined, orchestrated virtual networks.
NFV supports multi-versioning and multi-tenancy of network functions and allows use of a single physical platform for different applications, users and tenants. It also enables new ways to implement resilience, test and diagnostics, service assurance and security surveillance. Additionally, it facilitates innovation toward new network functions and services that are only practical in a pure software network environment.
Traffic and application visibility, performance management, mediation, correlation and real-time analytics are necessary and critical capabilities. These enable dynamic assurance and troubleshooting functions spanning both virtualized and non-virtualized networks, while providing a non-linear cost relationship between assurance solutions (delivering monitoring, analytics, testing and troubleshooting) and traffic levels.

As shown in the following excerpt, the strongest driver for testing of NFV is that it shortens time to market for new services. This can be accomplished in several ways, including by removing the siloed business models into which carriers are currently locked. Additionally, almost all service providers express concern that revenues are not keeping up with the increased demand for bandwidth and network capacity. While opex and capex savings from NFV are considered a given, the primary driver for NFV is the ability it provides operators to rapidly deploy new, revenue-generating services. Combining NFV with SDN, operators hope to offer customers these new services in an automated fashion on an as-needed basis and at a scale that is tailored to the customer's needs.
