Intelligent tunnel assignment and dynamic SLA threshold configuration to increase availability and utilization of SD-WAN tunnels

In one embodiment, a supervisory service for a software-defined wide area network (SD-WAN) tracks a performance metric for a tunnel in the SD-WAN. The supervisory service computes a cumulative distribution function (CDF) for the tracked performance metric. The service assesses curvature of the CDF f...

Zusammenfassung:	In one embodiment, a supervisory service for a software-defined wide area network (SD-WAN) tracks a performance metric for a tunnel in the SD-WAN. The supervisory service computes a cumulative distribution function (CDF) for the tracked performance metric. The service assesses curvature of the CDF for the tracked performance metric relative to a service level agreement (SLA) threshold of an application for that performance metric. The service controls assignment of traffic for the application to the tunnel, based on the assessed curvature of the CDF for the tracked performance metric relative to the SLA threshold of the application for that performance metric.
