Discover how to create a Linux bridge that merges two distinct network fabrics in this 28-minute conference talk from the Linux Plumbers Conference. Learn about the motivation behind this approach, the convergence of a vanilla network segment with a high-performance fabric, and the reasons for choosing the Linux bridge. Explore device-to-bridge and bridge-to-device learning techniques, and understand the minimal extensions required for the device driver. Gain insights into the remaining challenges and future developments. Presented by Alexandra Winter at LPC 2022, this talk covers topics such as IBM Z, Hypersockets, Linux bridge implementation, virtualization, and Switch Dev device drivers.
