SDN arises from the demands of pervasive cloud computing and changes the way we approach networking. The key concept of SDN is to move control out of the switches into a dedicated server that has a global view of the network state. This breaks fundamentally with existing principles of layer 2 and layer 3 networking where each switch has autonomous control.
This research provides an in-depth assessment of the SDN market including business models, operator and vendor strategies and a quantitative assessment of the industry from 2016 to 2020. This report includes use cases of real SDN deployments including analysis of benefits and challenges. The report also evaluates SDN strategies and product lines of a wide range of both well-established and new vendors.
The report addresses the following key topics:
- SDN Technical Brief: A concise but clear account of what exactly defines SDN and how it relates to NFV.
- Standards and Open Source: An assessment of the dynamic SDN open source community – who does what, and which are the initiatives to watch.
- The Case for SDN: What drives enterprises and carriers to deploy SDN? What can they expect from SDN?
- Factors Holding Back SDN: What are the drawbacks of SDN? What is holding back SDN deployment?
- Service Provider, Vendor and Enterprise Strategies: An assessment of the choices and dilemmas faced by vendors, carriers and enterprises when it comes to developing SDN products and deploying SDN networks. Includes case studies.
- The SDN Market: A forecast of how the SDN market will evolve between 2016 and 2020, taking into account global regional differences.
- Migration to SDN: Our exclusive step-wise guide to migration to SDN.

- What value can SDN bring to your business?
- How much of SDN is real and how much is hype?
- How can you migrate your existing network towards SDN?
- If a vendor claims their solution is SDN, how to evaluate this?
- How does SDN tie in with NFV (Network Function Virtualization)?
- What exactly is SDN? What are its key components and features?
- Which standards and open source initiatives are the most compelling? Will they be successful?
- How are service providers, carriers and enterprises deploying SDN? What are their drivers? Does SDN deliver on its promise?
- How are vendors responding to the SDN challenge? Who’s defending, who’s contending and who’s new on the block? Who’s teaming up with whom?
Select Report Findings:
- The global market for SDN will reach 11.5 Billion US$ by 2020. This includes both open and proprietary SDN, but not the market for NFV.
- In 2016 and 2017, carriers and enterprises will do mostly pilots and early deployments, including mixed and hybrid solutions. SDN will become truly main stream between 2019 and 2020.
- The openness promoted by SDN has a strong impact on the networking industry. New contenders such as Big Switch Networks take market share from incumbents such as Juniper and Cisco. Established vendors such as IBM and Hewlett-Packard and system integrators such as Accenture are creating new roles for themselves in the SDN market.
- The SDN market is fragmenting rapidly. Vendor driven open source communities appear almost monthly, competing with each other and proprietary solutions. OpenFlow will remain the most significant SDN standard. OpenDaylight is currently most significant open source initiative in the SDN space. Fragmentation will play into the hands of incumbents such as Cisco, Juniper and Huawei.
