The What and Why of Network Function Virtualization (NFV)

Network Functions Virtualization (NFV) is an industry-wide initiative that has captured the imagination and commitment of the telecommunications industry in the past year.

Many industry initiatives have focused on improving the bandwidth delivered over the telecom access networks and a wide portfolio of technologies that improve the spectral efficiency, bandwidth and robustness of mobile networks.  With NFV, the industry is turning its attention to the core network, which is where the software, appliances, and algorithms that run these complex networks reside.

There has been a multi-decade run of “black box” systems from legacy vendors.  The entire ecosystem is changing as a decoupling occurs between functionality and physicality of the network.  The network effect is taking hold as a decoupling of systems takes place.

The business motivation for NFV is improvement in CapEx and OpEx, service velocity and the potential to improve customer experience.   However, the size, scale and scope of telecoms networks is such that there are many steps along the way, and a progression/roadmap that when turned from the concept to the reality more complex and worthy of deep analysis.
