Versa Networks has been granted a patent for methods and systems to manage traffic across a wide area network (WAN). The patent involves identifying and policing Direct Internet Access (DIA) traffic at a first node, as well as adjusting the policing based on a comparison with Software-Defined WAN (SD-WAN) traffic. The method allows for increasing or decreasing the policed bandwidth of DIA traffic depending on the SD-WAN traffic threshold.

Managing traffic across a wan based on sd-wan traffic
A recently granted patent (Publication Number: US11765579B2) describes a method for managing traffic across a wide area network (WAN). The method involves identifying incoming traffic as either Direct Internet Access (DIA) traffic or Software-Defined WAN (SD-WAN) traffic at a WAN interface of a first node. The DIA traffic is received from the WAN without passing through the SD-WAN. The DIA traffic is then policed at the first node, and the policing is adjusted based on a comparison between the SD-WAN traffic and an SD-WAN traffic threshold.
The adjustment of policing involves increasing the policed bandwidth of the DIA traffic at the first node if the SD-WAN traffic received from the WAN is below the SD-WAN traffic threshold. Conversely, if the SD-WAN traffic received from the WAN is above the SD-WAN traffic threshold, the policed bandwidth of the DIA traffic is decreased. Policing the DIA traffic at the first node includes dropping any DIA traffic that exceeds the policed bandwidth.
The patent also includes additional claims related to the method. Claim 2 specifies that the DIA traffic is policed at the first node on a per-forwarding class basis. Claim 3 further specifies that the DIA traffic is policed at the first node on a per-forwarding class basis using forwarding class-specific weights.
In addition to the method, the patent also describes a computing device for shaping traffic across a wide area network. The computing device includes a memory and processor, with the memory storing instructions that, when executed by the processor, cause the processor to perform the steps outlined in the method.
Furthermore, the patent includes a non-transitory computer-readable storage medium that stores computer-readable instructions. When executed by a processor, these instructions cause the processor to perform the steps outlined in the method.
Overall, this patent presents a method and related devices for managing traffic across a wide area network, specifically addressing the policing and adjustment of Direct Internet Access (DIA) traffic based on Software-Defined WAN (SD-WAN) traffic levels.
