Zephyr has had its own abstraction for network buffers ever since the creation of its Bluetooth and Networking stacks that were part of the project's public launch back in 2016. The presenter is the original author of the buffer implementation and still acts as maintainer for it. The presentation will go through the original use cases, related design decisions, key terminology, and how the implementation has evolved over time as Zephyr has grown and received more users and requirements for the subsystem.

The presentation will also go through common mistakes/oversights that user make when starting to use the APIs, and show some best practices to avoid them. Finally, there will be an overview of some of the latest enhancements and new convenience APIs of the network buffer subsystem.
