What’s SD-WAN?
Software-Defined Wide Area Networking (SD-WAN) is a revolutionary way to simplify the approach to configuring enterprise networks using virtualized WANs managed from a single management unit.
Unlike traditional WANs, SD-WAN offers greater network flexibility, increased reliability and significant cost savings.
What are its features?
SD-WAN is WAN virtualization
In the same way that server virtualization disconnects physical hardware from the logical virtual servers running on it, WAN virtualization is where a logical WAN connection (to the Internet or between branch offices) can simultaneously use multiple underlying connectivity technologies (such as xDSL, MPLS, mobile and fiber) presenting itself to users and applications as a single stable connection both to the Internet and between different corporate locations.
SD-WAN is intelligent
An SD-WAN network is able to monitor the status and quality of connections used by the WAN and use this information to manage traffic intelligently.
Once an SD WAN device is configured, all traffic is automatically managed by the software according to the rules previously set on the device and without the need for any interaction with an operator.
SD-WAN is managed and monitored centrally.
Branches can be procured, monitored and managed centrally using an SD-WAN controller that allows network administrators to have full control of remote devices using a single interface.
Complex VPN configurations can be automatically created and implemented to securely connect thousands of branch offices (using any connectivity available in each location), with centralized monitoring and notifications that provide a real-time view of the WAN health and global availability of branch offices.
SD-WAN is a secure VPN
Using an encrypted VPN, branch offices gain secure access to both the local network and cloud resources. SD-WAN connects branch offices more efficiently and cost-effectively by combining the bandwidth of multiple connections into a single logical WAN (VPN) connection.
