Cost-Effective, Scalable Quality of Experience Monitoring for SD-WAN Networks (2019)

By Edouard Karam & Greg Spear, Accedian

Today, SD-WAN vendors offer some type of quality of service (QoS) visibility, but they do not extend this to true application quality of experience (QoE).

While SD-WAN solutions provide visibility into such things as network performance between platforms or bandwidth/capacity usage for top protocols, these metrics are provided only within the walls of the network. As such, they cover application performance from WAN edge to WAN edge only—not to the true edge (the end user’s experience).

This paper will focus on the importance of, challenges surrounding, and requirements for true SD-WANQoE visibility, including a look at costing benefits of metadata-based monitoring compared to traditional stream-to-disc.
