SD-WAN is a software-defined approach to managing the wide-area network, or WAN. SD-WANsimplifies the management and operation of a WAN by decoupling (separating) the networking hardware from its control mechanism.
A key application of SD-WAN is to allow companies to build higher-performance WANs using lower-cost and commercially available Internet access, enabling businesses to partially connection technologies such as MPLS.
Key advantages include:
- Reducing costs with transport independence across MPLS, 3G/4G LTE, etc.
- Improving business application performance and increasing agility.
- Optimizing the user experience and efficiency for SaaS and public cloud applications.
- Simplifying operations with automation and cloud-based management.
