Understanding OPNFV 22 to grow as we have moved from 2G to 4G/LTE, with 5G around the corner. vEPC enables mobile network operators (MVNO) and enablers (MVNE) to use a virtual infrastructure to host voice and data services rather than using an infrastructure built with physical functions. A prerequisite to providing multiple services simultaneously requires "network slicing" or the network multi-tenancy, a capability also enabled by vEPC. In summary, vEPC can cut opex and capex while speeding up delivery and enabling on-demand scalability. vIMS (Virtual IP Multimedia System) OTT competitors are driving traditional telco, cable and satellite providers towards offering voice, video, and messaging over IP as a response. A virtualized system can offer the agility and scalability required to make IMS an economically viable offering to effectively compete with startups. This list is by no means comprehensive, even in the short term. Numerous other use cases exist today and new ones are likely to emerge. The most obvious one is 5G. With 50x higher speeds, 10x lower latencies, machine-to-machine communication, connected cars, smart cities, e-health, IOT and the emergence of mobile edge computing and network slicing, it is hard to imagine telecom providers or enterprises being successful with physical network functions. NFV at ETSI In 2012, ETSI took the reins of the standardization process for NFV, with the goal of defining just what NFV was and what the industry was going to do. The Industry Specification Group (ISG) for NFV at ETSI has grown from seven to more than 300 individual companies, and has published more than 40 documents with details of how NFV should be implemented and tested. The ongoing contribution of ETSI in furthering the cause of NFV in the standards arena has been invaluable. Let us briefly look at three important NFV-related documents created by the ISG. NFV Architectural Framework Document This document is important because it forms the reference against which all the ISG working groups work. ETSI NFV Architecture (source ETSI)
