Standardization SDN&NFV

摘要

Software Defined Networks (SDN) is a new approach to manage network services by decoupling the data and control planes and providing an open interface between them able to support pro-grammability. In parallel, Network Functions Virtualization (NFV) is a network architecture concept based on the application of technologies inspired in current cloud infrastructures to virtualize traditional network functions (mobile services, CDNs, Firewalls, etc.) and build network services by interconnecting these virtualized functions. SDN and NFV are complementary and they have become two key paradigms in today's networking. Due to its impressive growth, many standardization bodies such as IETF, IEEE, ETSI, ITU-T, ONF, TM Forum and 3GPP, and open source projects such as OpenStack and OpenDayLight among others, are taking positions to define frameworks, protocols, data models and reference implementations that pave the way for interoperable, extensible and standard SDN and NFV solutions.
