In addition to SD-WAN router vendors, the SD-WAN router market consists of providers of software, cloud, and managed services. They offer Internet-as-a-Service in a package that includes multiple WAN connections, bonding technology to increase bandwidth and reliability, and cloud-based management platforms.
As these service providers do not have their own SD-WAN routers, they source for SD-WAN routers from the SD-WAN hardware vendors in order to enable their services. The emergence of these service providers has driven the demand for SD-WAN routers.
