Oxide Networking with Ryan Goodfellow

Episode 12 – Oxide Networking with Ryan Goodfellow.

A conversation with Ryan Goodfellow about Rust networking at Oxide. We will explore the Oxide computer stack with a focus on network, including their fully integrated cloud computer, programmable networking with P4 and Dendrite, the Maghemite routing stack, and OPTE — a Rust-based packet engine running inside the kernel. Ryan also shares how his background in large-scale network testbeds led him to help design Oxide’s rack-scale system and its modern approach to routing, observability, and hardware–software co-design.
