Full-stack SDN
Gianni Antichi, Gábor Rétvári · 2020
This paper challenges the common assumption that SDN networks shall be run only at lowest layers of the stack, i.e., L2 and L3. Using as use case data center networks providing virtualized services, we show how state-of-the-art solutions already employ some application-level processing via a central controller. With this in mind, we question if the lessons learned from a decade of SDN networking can be also extended to the upper layers. We make the case for a full-stack SDN framework that encompasses all protocol layers in the network stack, and call for further research in the area.
