A Survey of Software-Defined Networking

Contributors: Bruno Astuto Arouche Nunes, Xuan Nam Nguyen and Thierry Turletti.

We wrote a survey of the emerging field of Software-Defined Networking (SDN). SDN is currently attracting significant attention from both academia and industry. Its field is quite recent, yet growing at a very fast pace. Still, there are important research challenges to be addressed. We look at the history of programmable networks, from early ideas until recent developments. In particular we described the SDN architecture in detail as well as the OpenFlow standard. We provided an overview of current SDN implementations and testing platforms and examined network services and applications that have been developed based on the SDN paradigm. We concluded with a discussion of future directions enabled by SDN ranging from support for heterogeneous networks to Information Centric Networking (ICN). The survey has been published in the IEEE Surveys and Tutorials journal [9] . This paper is among the top downloads on IEEE Exlpore in December 2014.
