    Building and testing network stacks with Rama

    Episode 38: Building and testing network stacks with Rama.In this Protocol Shorts episode of Netstack.fm, Glen talks with Brecht Stamper about Rama, the modular Rust framework for building clients, servers, proxies, and other network systems. Brecht shares how he came to understand Rama’s core idea that everything is a service, and why that simple input to output contract makes it easier to compose complex stacks without constantly inventing new traits or glue code. They also discuss how Rama helps with testing, including gRPC client and server logic without spinning up real HTTP or TCP infrastructure. The conversation then moves into practical production lessons, such as gRPC latency caused by TCP_NODELAY, the role of OpenTelemetry and logging, and how Rama can provide better abstractions while still allowing low level control. Later in the episode, Glen and Brecht explore Rama’s evolving extension system, including the move toward append only extensions, clearer separation between request and connection state, and support for complex scenarios such as HTTP/2 streams and protocol upgrades. They close with thoughts on where Rama is heading next, including HTTP/3, QUIC, better developer tooling, performance work, and making more hard won network fixes available to everyone through the framework.

    dial9: from black box to insight in Tokio

    episode 37: dial9: from black box to insight in Tokio. In this episode of Netstack.fm, Glen talks with Jess Izen and Russell Cohen from Amazon about Dial9, a new tool for understanding what’s happening inside Rust and Tokio applications. They explain how it captures events from different layers of your system and puts them into a single timeline, making it much easier to debug tricky performance issues and unexpected behavior. They also share how Dial9 came out of real debugging challenges at Amazon, where engineers often had to rely on complex, low level tools. The goal with Dial9 is to make those kinds of insights more accessible, so developers can diagnose problems faster and with less guesswork, while the tool continues to evolve with new features and improvements.

    Protocol Shorts: TLS Encrypted Client Hello

    Episode 33 – Protocol Shorts: TLS Encrypted Client Hello. This episode explores TLS Encrypted Client Hello (ECH) and how it improves privacy on the internet by hiding sensitive metadata that was previously exposed during the TLS handshake. While traditional TLS encrypts the actual data exchanged between client and server, key details like the Server Name Indication (SNI), which reveals the website you are visiting, remained visible to intermediaries such as ISPs or network middleboxes. Glen explains how ECH addresses this gap by encrypting most of the Client Hello message using keys obtained via secure DNS, preventing third parties from easily identifying user activity. The discussion also covers real-world implications, including the impact on network infrastructure that relies on traffic inspection and the role of cloud providers in TLS termination.

    Protocol Shorts: MITM Proxies and Transparent L4 Interception

    episode 31 — Protocol Shorts: MITM Proxies and Transparent L4 Interception. In this second "Protocol Shorts" episode, we look at man-in-the-middle proxies from the transport layer up. The episode explains how HTTP proxies, HTTP CONNECT, and SOCKS5 differ, why they all assume a proxy-aware client, and what changes when a transparent layer 4 proxy is inserted by the operating system instead. From there, we dig into protocol detection from the first bytes on the wire and into the BridgeIo abstraction in Rama: a way to relay and inspect stacked handshakes incrementally instead of terminating every protocol upfront.
