#sd wan benefits

Until now, private leased lines are still used by many despite the relatively high cost of deploying a WAN (Wide Area Network), its lengthy provisioning time, its complex operation and maintenance, not to mention the guaranteed bandwidth. These various WAN requires specific hardware components provided by network providers and have their own strengths and weaknesses ranging from ease of deployment, management, added functionality, network security, and cost considerations. In order to bridge the gap between the performance and stability of an MPLS or leased line and the cheaper option with VPN, a Software Defined WAN (SD-WAN) solution was developed in 2014. SD-WAN can utilize multiple types of network connectivity and interlink them simultaneously to create a resilient and robust corporate data network. “SD-WAN is a software based solution to simplify delivery of WAN services and network operations. As such, it simplifies the deployment of customer branches by providing connectivity when and where it is needed.” For example, enterprises with multiple sites that require connectivity can leverage on an SD-WAN solution. SD-WAN can utilize all of these network transport and dynamically determine what type of traffic can pass through-- ensuring the best path for connectivity and thereby assuring optimum location, availability, and resiliency.
