| | May 20176CIOReviewAbout a decade back, there were as less as zero companies in the SDN market--unchartered waters waiting to be tested. Today, the tables have turned; some 1400 different vendors have sprung up, decimating the monopoly of hardware-oriented network orchestration. It's all about control--the whole idea of moving the network control away from physical layers and pushing it into the software realms, which has made SDN a hit in the networking metaverse.It is not without reason that 2017 stands to be declared the year for SDN and for most adopters, it is SD-WAN that has become a popular choice to kick-off their "software-defined" initiatives.Gartner predicts that by 2019, nearly 30 percent of the enterprises would have adopted SD-WAN technologies and few more years into the future, SD-data centers would have joined the club. It doesn't stop there though; even ISPs are jumping on the SDN bandwagon, with the sole purpose of having the ability to remove the network control complexities and reduce their OpEx and CapEx.Discussions on low-cost technologies can never be wrapped up, without the mention of open source paradigms. To that end, the development of SDN products has its own share of communities that constantly fan the flame of free and experimental software. For instance, the OpenFlow standard, one of the first network messaging protocols has remained the preferred choice for almost a decade now. But more open source projects, backed by the Open Networking Foundation are permeating the industry, such as OpenDaylight and FlowVisor. At the crossroads of provisioning high and flexible bandwidth and cheaper network control, the SDN industry is headed for more such projects from open source communities as well as products from market leaders with competitive price tags. Poised to hit the $130 billion benchmark by 2022, the SDN market is awakening to a red-letter day every time a new application or SDN-enabled network device makes its way, battle-tested to sustain in the data deluge. Experts believe that there will be more consolidations in the market, through the increasing M&As that will favor the entry of small and talented players into the competitive market. Delivering more insights into the complex landscape, CIOReview is presenting its annual special edition on SDN technology.Let us know your thoughts!Jeevan George Managing Editoreditor@cioreview.comEditorialControl takes Center StageCopyright © 2017 ValleyMedia, Inc.
