The corporate network is facing unprecedented pressure from the growth of cloud, mobility, voice, and video traffic. And with companies increasingly decentralized, branch office networks are becoming more complex and expensive to scale and secure. The result is spiraling network costs, poor end-user experience, increased security risks, and a management nightmare.
Enterprises are already adopting Software-defined wide area networking (SD-WAN) as a long-term solution for these network challenges. SD-WAN creates an overlay on an existing enterprise network, making it more flexible without the expensive and time-consuming challenge of ripping and replacing existing connections. It abstracts the control and configuration functions hardwired into network routers and switches, and redefining them in software.
