Wide Area Network (WAN) allow companies to extend their network over a large geographical area, but when companies try to expand their network to even larger area and not to forget across multiple carriers’ networks, they face major operational challenges. Software-defined wide area network (SD-WAN) overcomes these networking challenges, by separating networking hardware from its control mechanism. Gartner, predicts that up to 25% of users will manage their WAN through software within two years. Revenue from SD-WAN vendors is growing at 59% annually, Gartner estimates, and it’s expected to become a $1.3 billion market by 2020.
