SDNs can automate and manage WAN operations as well. Google is using OpenFlow to interconnect data center over a WAN.
And startup Glue Networks is targeting Cisco's installed base of WAN routers as a sweet spot for its SDN WAN offerings.

Major IT trends such as SaaS, private clouds, BYOD, mobility and voice/data convergence are stressing the quality of links in an enterprise WAN, as analyst Lee Doyle notes here. WAN links now require improved security, lower latency, higher reliability and support for any device in any location to accommodate these trends.
SDN can help enterprise IT accomplish this without the expense of upgrading individual WAN links, Doyle notes. The technology can allow for prioritization of key applications and traffic types, ease provisioning for new sites, new applications, and changed traffic priorities, enhance security and more tightly link WAN service to specific applications.
That's what Glue Networks is after. Glue's gluware software runs in the cloud and provides a cloud-based service for turning up remote sites and teleworkers worldwide. It is designed to lower the cost of private WAN networking by automating those operations and handling ongoing maintenance, monitoring, life-cycle management and feature extension.
Some of those features might include Cisco's WAAS Express, ScanSafe, ISE, MediaNet and TrustSec services.
The software automates the provisioning of voice, video, wireless, LAN networking, IP addressing, PKI security, firewalls, VLANs and ACLs, and allows users to configure a meshed, spoke-to-spoke, low-latency infrastructure that is QoS-enabled, the company says.
