SD-WAN Services

What is SD WAN? The software-designed WAN (SD-WAN) 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 datacenters – over large geographic distances.

The Importance of SD WANs Change is on the horizon, and businesses are looking for solutions to make their networks more flexible and responsive to their needs. Enterprise managers are often faced with the following challenges when it comes to managing IT infrastructure:

Cost management of networks Lessening the complexity of networks Improve the performance of applications while increasing flexibility Companies have faced operational challenges as they extend their reach over greater distances around the world. Some of the issues that they have faced as they expanded farther included data packet loss and network congestion. All modern applications such as streaming media, video teleconference calls, virtual apps, and VoIP calls require low latency.

Traditional WANs utilize MPLS (multiprotocol label switching), which sends data from one node to another. This technology is heavily reliant on terrestrial connections and underlying hardware in order to route information from the corporate headquarters to the branch offices. Users have often encountered high latency when attempting to use company appliances within the network. Configurations are also difficult as individual changes would have to be applied, and the changes themselves were often based off of templates that may not push through and affect the branch accordingly.
