Episode 8 – Fuchsia's Netstack3 with Bruno Dal Bo Silva.
In this episode our guest is Bruno Dal Bo Silva, Staff Software Engineer at Google. We will dive into his path into networking and Rust, and the story behind netstack3, the Rust-based networking stack built for Google’s Fuchsia operating system. We cover its origins from the Go-based netstack, why Rust was chosen, and the challenges of implementing a full range of protocols — from TCP and UDP with their POSIX socket API to the many less-visible but essential pieces like ARP, ICMP, IPv6, DHCP, and more. We hope you brought a bowl as you're in or a juicy letter soup with this one. Bruno also shares insights on where he sees the future of netstack3 — including its potential beyond Google.
