Systems and methods for protective proactive adaptive active bandwidth measurement in SD-WAN networks

Abstract:

The present disclosure is directed to determining bandwidth capacity in a WAN path and includes one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations including, selecting a SD-WAN path for which to determine bandwidth capacity, wherein the path is associated with a Quality of Service (QoS) shaper having a pre-determined shaper rate, incrementally increasing a test load applied on the selected path, wherein the test load is applied concurrently with existing user traffic, calculating a performance score for the path after each increase in the test load, determining a performance of the path based on the calculated performance score, and updating the shaper rate of the QoS shaper based on the performance of the path.
