Intent-based policy optimization in SD-WAN
Pham Tran Anh Quang, Sébastien Martin, Jérémie Leguay, Xu Gong, Feng Zeng · 2021
To optimize bandwidth utilization in wide area networks, a controller typically maintains policies at edge routers. In this context, our demonstration presents a versatile policy optimization model that carefully selects the set of overlay links for each application based on its requirements and the overall intent of the operator. The optimization of policies is realized using an SLA prediction model for several intents. We demonstrate, for instance, that latency is improved by 40% when the high-quality intent is selected.
