NETWORK FUNCTION VIRTUALIZATION Network Functions Virtualization (NFV) is a major strategic initiative for network operators
worldwide. In January 2013, the European Telecommunications Standards Institute (ETSI)
launched an initiative sponsored by seven of the largest operators in the world: AT&T, BT,
Deutsche Telekom, Orange, Telecom Italia, Telefonica and Verizon to establish requirements
and an architecture for the virtualization of network functions. In a relatively short time, the
number has increased to over 150 operators, vendors, and technology providers. Data center
solutions have leveraged virtualization technology for years, but the telecommunications
network has not widely adopted the technology for its infrastructure for a number of reasons,
but operators wanted to change that through the ETSI process. These network operators see
tremendous potential in NFV for telecommunications deployments. The stated benefits from
the NFV ISG include1:
• Reduced operator CAPEX and OPEX through reduced equipment costs and reduced
power consumption
• Reduced time-to-market to deploy new network services
• Improved return on investment from new services
• Greater flexibility to scale up, scale down or evolve services
• Openness to the virtual appliance market and pure software entrants
• Opportunities to trial and deploy new innovative services at lower risk
The goals from the ETSI NFV Industry Specification Group (ISG) for the standards framework
is to address the technical challenges for NFV, which include2:
• Ensuring that virtualized network platforms will be simpler to operate than what
exists today
• Achieving high performance virtualized network appliances, which are portable between
different hardware vendors and hypervisors
• Achieving co-existence with legacy hardware based network platforms whilst enabling an
efficient migration path to fully virtualized network platforms which re-use network operator
existing BSS and OSS
• Management and orchestration of virtual network appliances (particularly alongside legacy
management systems) while ensuring security from attacks and misconfiguration
• Maintaining network stability and service levels without degradation while under load or
during relocation
• Ensuring the appropriate level of resilience to hardware and software failures
