The growing interest in SD-WAN has led to a standardization of SD-WAN across the industry. The Metro Ethernet Forum (MEF) published its first paper in July 2017, introducing the SD-WAN component of the SD-WAN end-to-end solution. MEF also proposes service specifications for defining frameworks and APIs for all interfaces of SD-WAN components.
SD-WAN-supported transport-independent SD-WAN tunneling and traffic steering capabilities help organizations save on expensive MPLS bandwidth. Centralized monitoring of automation capabilities and SD-WAN reduces the complexity of deployment and management of enterprise sites. However, SD-WAN may not really replace MPLS. Enterprises may still like MPLS for critical traffic. Hybrid WAN architecture (SD-WAN and MPLS work together) is today’s most popular solution. The SD-WAN standardization work will further enhance the confidence of enterprises to integrate SD-WAN into their business.
