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. This eBook from Calsoft talks about SD-WAN trends and analysis. It also describe its benefits, key players, market landscape, and some really interesting statistics and forecast.

1. SD-WAN: AN OVERVIEW
The software-defined wide area network (SD-WAN) is a specific application of software-defined
networking (SDN) technology applied to WAN connections, which are used to connect
enterprise networks – including branch offices and data centers – over large geographic
distances.
A WAN might be used, for example, to connect branch offices to a central corporate network,
or to connect data centers separated by distance. In the past, these WAN connections often
used technology that required special proprietary hardware. The SD-WAN movement seeks to
move more of the network control is moved into the “cloud,” using a software approach.

Current WAN architecture has few challenges like
 Traditional connectivity with costly MPLS causing inefficiency of using diverse
applications.
 Lack of network security and reliability features
 Lack of optimization of SaaS and cloud based services within network
 Lack of automated provisioning of resources
