Summary

Recommendation ITU-T Y.3302 provides the functional architecture of software-defined networking (SDN)
with descriptions of functional components and reference points. The described functional architecture is
intended to be used as an enabler for further studies on other aspects such as protocols and security as
well as being used to customize SDN in support of appropriate use cases (e.g., cloud computing, mobile
networks).
This Recommendation is based on ITU-T Y.3300 and ITU-T Y.3301. Recommendation ITU-T Y.3300
describes the framework of SDN including definitions, objectives, high-level capabilities, requirements and
the high-level architecture of SDN; Recommendation ITU-T Y.3301 describes more detailed requirements.

Keywords
Abstraction, functional component, multi-layer management, orchestration, programmability, software-
defined networking.
