The Software-defined networking (SDN) in the WAN: solution options and vendor opportunities

The Software-defined networking (SDN) in the WAN: solution options and vendor opportunities

Wide-area network software-defined networking (WAN SDN) blurs the line between network management and control, disrupts the network management market and pits new and incumbent vendors against each other. This report provides recommendations for CSPs that are assessing WAN SDN technologies, and provides WAN SDN vendors with a competitive benchmark.


About this report
Executive summary
Harnessing SDN’s automation benefits in the WAN is a much more complex challenge for CSPs than it has been in the data centre
WAN SDN comes in four basic flavours; CSPs can adopt two quickly, but the other two will require a more disruptive SDN element in NGNs
Recommendations
CURRENT MARKET STATE AND DRIVERS
Simple WAN SDN deployments that target new revenue are proceeding; the cost and revenue benefits of more-disruptive deployments will follow
Key WAN SDN market drivers and inhibitors
Four distinct SDN approaches automate the management of the WAN [1]
Four distinct SDN approaches automate the management of the WAN [2]
SD-WAN implementation models overlay existing control planes with programmable SDN functionality at the WAN edge
MARKET REVENUE AND OPPORTUNITIES
Revenue forecasts and definition: how Analysys Mason characterises this high-growth space
SDN investments will come from cannibalising NMS spending, opex savings and WAN infrastructure spending delay and avoidance
WAN configurator and SD-WAN solutions have been adopted; multi-layer control and native SDN remain experimental
SDN’s disruption of the WAN is changing traditional vendors’ businesses and opening the door for new entrants
Successful initial deployments are proving the benefits of WAN SDN
Four WAN SDN vendors have the platform strategies or the assets needed to successfully develop a platform to become market leaders
CONSIDERATIONS AND PREDICTIONS FOR WAN SDN
SDN initiatives are mostly striking the right balance between openness and open source, pushing market spending growth
The future of WAN SDN: the first three approaches will converge around a platform play
A single native SDN approach is ultimately likely to control both WAN and data centre networks, pushed by developments at the edge
WAN SDN is influencing the future shape of network operations; native SDN will be needed to manage 5G networks
