Netdev 0x15

The recent Netdev 0x15 conference included a number of papers diving into the technology behind Linux as a network operating system. Slides and videos are now available on the conference web site.
Network wide visibility with Linux networking and sFlow describes the Linux switchdev driver used to integrate network hardware with Linux. The talk focuses on network telemetry, showing how standard Linux APIs are used to configure hardware instrumentation and stream telemetry using the industry standard sFlow protocol for data center wide visibility.
Switchdev in the wild describes Yandex's experience of deploying Linux switchdev based switches in production at scale. The diagram from the talk shows the three layer leaf and spine network architecture used in their data centers. Yandex operates multiple data centers, each containing up to 100,000 servers.
Switchdev Offload Workshop provides updates about the latest developments in the switchdev community. 
FRR Workshop discusses the latest development in the FRRouting project, the open source routing software that is now a defacto standard on Linux network operating systems.
