The software-defined wide-area network (SD-WAN or SDWAN) is a specific application of software-defined networking (SDN) technology applied to WAN connections such as broadband internet, 4G, LTE, or MPLS. It connects enterprise networks — including branch offices and data centers — over large geographic distances.
WHAT IS SD-WAN?
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, WAN connections often used technology that required special proprietary hardware. SD-WAN, on the other hand, utilizes the internet or cloud-native private networks. SD-WAN decouples the network from the management plane and detaches the traffic management and monitoring functions from hardware. It relies on four central components:
- Edge Connectivity Abstraction
- WAN Virtualization
- Policy-Driven, Centralized Management – Elastic Traffic Management
One simple site license includes everything you need for your managed SD-WAN experience.
- Cloud based management portal for viewing and configuration of all branch devices
- Seamless failover with IP transparency over multiple links and instantly reacts to keep your entire branch network connected.
- Prioritize and protect priority network traffic to ensure voice quality over broadband.
- Combine multiple links to create a faster and more reliable connection to any site in your network or the internet
- Automated encryption provides secure end-to-end transport between all your SD-WAN sites or your data center
- The ability to manage the SD-WAN edge device and implement and create layer 7 firewall rules at the branch level
- Provides visibility of applications rather than ports and protocols
- Application Optimization -traffic shaping and application prioritization
- Dynamic configuration- provides the Control Plane to change configuration on multiple or individual SD-WAN devices simultaneously
- Control Plane offers the ability to set, monitor and improve MOS scores to assess VOIP quality
- Deep Analytics – Integrated traffic analytics for application visibility and capacity planning
