What is SD WAN
The latest capability in the world of WAN is Cisco’s software-defined wide area network (SD-WAN). SD-WAN capabilities can be applied as a virtual overlay to a company’s current WAN connection, which today would typically be MPLS-based. An SD-WAN architecture can connect your remote offices and data centers, optimizing network performance, for a fraction of the cost of solely using MPLS. Enterprises are looking at SD-WAN to decrease the number of physical devices required to support applications and reduce the cost of maintaining technology deployed in branch locations.
Cisco SD-WAN, based on Viptela, will likely be the preferred solution for large, complex deployments, and Meraki will be the ideal product for simple, small-to-midsized businesses (SMBs).
