"CSPs are focusing on WAN SDN in a bid to deliver new revenue and reduce opex, which is unleashing a 'land grab' among vendors that want to take a share of this emerging and lucrative market."
This report quantifies and analyses four approaches to wide-area network software-defined networking (WAN SDN). It discusses the challenges faced by communications service providers (CSPs) and their vendor partners in deploying SDN to create a programmable WAN and how open-source software is affecting these challenges. The report also classifies and analyses WAN SDN vendors' solutions and approaches, highlights the leading vendors, and provides recommendations for CSPs and vendors.
Finally, the report provides recommendations for CSPs that are assessing WAN SDN technologies, and provides WAN SDN vendors with a competitive benchmark.
It is based on several sources.
Multiple briefings from SDN vendors worldwide. Many deals are being announced for SD-WAN and what some call ‘carrier SDN’ solutions. We have spoken to many key solution providers.
Analysys Mason’s internal research on network function virtualisation (NFV) and SDN, which permeates our Telecoms Software and Network research practice.
Interviews with CSP operations managers, who are currently using or procuring WAN SDN solutions.
Definitional material from the Software-Controlled Networking research programme.
This report provides answers to the following questions.
- What are the business and operational benefits of introducing SDN into the WAN?
- How will SDN be used to improve control in the WAN?
- Which are the leading vendors and what are their strategies?
- What is the forecast revenue for the WAN SDN market to 2020?
- What is the role of open-source software, specifically OpenDaylight and ONOS, in WAN SDN?
- What is the probable evolution of SDN, influenced by NFV and 5G, and will it integrate with data centre SDN?
