From the performance point of view, MPLS provides a reliable and fixed bandwidth level. Although this seems to be an advantage, today's traffic has very unpredictable performance requirements. Therefore, organizations need to lease MPLS connections to cope with the worst traffic load, which means that expensive bandwidth is idle in many cases, and at other times, MPLS connections may limit connections due to the increasing amount of data generated by modern networks and devices.

The bigger challenge is that although all traffic requires bandwidth to work, some applications, such as voice and video, need to continuously monitor latency requirements. When multiple applications are running in the same connection tunnel, it is necessary to prioritize the delay-sensitive traffic, which requires application identification, traffic shaping, load balancing and priority among different connections.

SD-WAN can recognize applications and adjust bandwidth and other services accordingly. It can start multiple parallel connections and then provide fine-grained load balancing among them. Once the available bandwidth drops, even the connection fails, or the delay-sensitive application starts, SD-WAN can ensure that the delay-sensitive application gets all the bandwidth space it needs, which is one of the reasons why the SD-WAN technical scheme is widely respected. Our SD-WAN technical solution can provide faster application acceleration for common applications of enterprises.
