SD-WAN vs SDN


The Software Defined Networking (SDN) concept and the OpenFlow protocol were introduced in 2011 to improve agility, flexibility, operational efficiency, and provide data networking options. The basis of SDN was to separate or separate control or management functions (planes) from network d

.

The SD-WAN architecture model is similar to SDN in many ways.

  • Centralized management or coordination: Control plane
  • Distributed Data Transfer Function – Data Plane
  • Application-driven traffic routing policy

SD-WAN, like SDN solutions, does not support interoperability between vendors. However, working groups from various industries in SDN and SD-WAN continue to propose and discuss the establishment of industry standards.

SD-WAN provides value to businesses of all sizes

SD-WAN vendors have focused on providing a productivity-enhancing WAN and have provided value to businesses of all sizes. Efforts to address SD-WAN interoperability focused on working with existing WAN infrastructure such as routers, firewalls, and forwarding services rather than multi-vendor SD-WAN solutions.

SD-WAN Achieves Visible ROI

SD-WAN is rapidly being adopted in the production environment of enterprises, regardless of industry or scale, because it can achieve a visible return on investment (ROI) that can be easily achieved. As of late 2018, SD-WAN has gone beyond the early adopter market approval stage to the early majority stage, with SD-WAN deployed in more than 10,000 production environments across the industry.
