Software Defined WAN

NTT ICT’s Software-defined WAN (SD-WAN) is a fundamentally different approach to WAN design that better deals with the performance, economic and security challenges created by data traffic growth, cloud, mobility and the Internet of Things.

With SD-WAN enterprises can provide secure connectivity, deploy new services and applications faster, improve network performance and simplify operational complexity with more choice in the WAN. 


Traditional WAN technologies like MPLS, VPLS and VPN tunnels struggle to meet the needs that enterprise IT now demands. Connecting applications hosted in a complex combination of private and public cloud environments is increasingly operationally intensive and expensive. Bandwidths and performance are put under pressure as it becomes easier to connect mobile devices to networks.

The SD-WAN solution comprises a number of advances in network technology that better support modern network requirements.
