The benefits of SD-WAN for enterprise networks are now well understood. By creating a managed overlay network with centralized control, enterprises have transformed their WAN into an intelligent and automated construct that increases scalability, service agility, and decreases operational complexity and cost. Enterprises are now looking at their SD-WAN infrastructure for more than just connectivity. They want to leverage it to deliver a range of IT services, such as the flexible and automated deployment of virtualized network functions, or to provide true end-to-end application visibility, control, and security. SD-WAN 2.0 is the infrastructure needed to offer this.
