SDN: the preferred solution for companies to build flexible networks


While software-defined networking (SDN) has a lot of talk, as business service providers are just beginning to adopt this technology radically changes the way running data centers and enterprise networks.


According to Infonetics marketing research company, the current market SDN expected to increase from $ 781 million in 2014 to thirteen billion dollars in 2019 . This market would be pulled up by enterprises and small service providers cloud (CSPs) acting Ethernet switches capable of adapting to different IT systems.

Indeed, the growth of SDN – which dematerialises switches and routers – is stimulated by the growing need of companies to move towards a more flexible approach to networking . This demand is also driven by the growth of cloud , mobile technology, big data and the Internet of Things (IoT). All of which, combined with each other, increasing the pressure on the spine of the network, who is asked to perform optimally even when the network is operated at full capacity and that the mass of data is increasing.

The complementary talents of NFV

Technology NFV (Network virtualization features) , sometimes seen as competing, is actually complementary to SDN . The one and the other offering a new way to design, implement and manage a network and its associated services. Where the SDN button to the “brain” of the network, to make the most efficient network and to automate services through an overview, the NFV focuses on optimizing critical parts of the network: services as such.

The SDN and NFV, both reporting to approach software network , were designed to make them more agile, scalable, innovative networks, particularly adapted to the imperative of working 7 days 7 and 24 hours 24 companies today. Although not dependent on one another, SDN and NFV make a perfect couple, each increasing the efficiency and effectiveness of the other. Thus, e SDN can be strengthened by its ability to automate the network through traffic steering protocols. NFV, meanwhile, takes care of optimum coordination between network capacity and paperless environments it hosts.

Commercial services offered by SDN

It would be pure folly to pass the technology before commercial services. The SDN is in this logic and brings two key benefits for businesses: speed and agility , both crucial in a business environment where technology and the global economy are constantly changing.

The benefits of SDN speak for him; primarily its ability to streamline the network infrastructure, to treat more rapidly process and manage a comprehensive and efficient way the most sensitive networks and the most susceptible to threats to their cloud security. Between the growing importance of big data, mobile traffic and data sharing services, many companies feel overwhelmed. SDN offers a real solution.

Indeed, the SDN enables them to manage the puzzle that became network cloud security. The “2015 Information Cloud security Breaches Survey” study found that 90% of large British companies have experienced a cloud security breach last year . If the virus still accounted for the majority of attacks, more than half of the companies had been involved in phishing attempts. Unlike conventional networks, the SDN enables a renewed cloud security approach, in “clusters”, either for the app and BYOD machines.

The savings from the League have yet to be quantified. However, it is likely that the SDN enables a reduction in costs related hardwares and the management and operation of networks. By integrating all of these elements into the equation and adding improved network efficiency, the League is undoubtedly a win-win type of operation, including for SMEs.

The networks will not be the only ones to enjoy the benefits of SDN. By the very nature of its paperless data infrastructure, the League of Nations should improve the dexterity and flexibility of the entire business model : companies become more competitive, decrease their response time drastically and improve data management in the end line.


For SDN, companies have so far lagged service providers. Suppliers have indeed had the time to develop and offer innovative services and income generation, often via the cloud , allowing companies to bear the growing weight of their data. These, however, have long seen the network as a necessary evil . By corollary, they have been very cautious with regard to the League of Nations. However, the more they will become familiar with these technologies, the more they will be able to release strong ties that bind them to the patented materials, the FAU and other dedicated services.
