What is SD-WAN?


SD-WAN is an acronym for software-defined networking in a wide area network. This software uses a centralized control function. This is to enhance networking and security and sensibly direct traffic across the WAN.

SD-WAN and Latency

SD-WAN solutions increase the performance of an application, which then enhances the experience of the user and increases the profit of the business. This also reduces costs for the IT.


Let us first define latency. Latency is the amount of time for a packet of data to travel across the user’s network services to its destination. A high latency time accounts for poor communication, negative end-user experience, and work disruption.
Many wonder how sdwan affects latency. Keep in mind that most SD-WAN software sits outside of the data path. This means it won’t disrupt any performance. It helps steer any traffic away from latency issues. This is by detecting the best traffic routes and sending the packets through the pre-approved pipes that are set in the configuration settings.
Managed SD-WAN lowers latency by detecting any trouble areas. This helps the user avoid said trouble areas when sending data. This also allows the user to pinpoint and fix traffic issues quickly and safely.
