This paper presents the first empirical study evaluating Jev, a general-purpose decision model, for network traffic application classification using only early-flow packet features on the CESNET-QUICEXT-25 dataset. Labeled examples boost Jev's accuracy from 9.80% to 34.50%, but trained tree ensembles and GPT-5.6 Sol still outperform it, suggesting labeled in-context examples alone are insufficient to match dedicated classifiers.

Cloudflare has open-sourced quiche, a Rust implementation of the QUIC transport protocol and HTTP/3, used in their edge network and adopted by Android and curl for enhanced network performance.

CVE-2026-42530 discloses a use-after-free vulnerability in nginx's HTTP/3 QUIC module.

savearoundtrip is a tool that checks if a domain publishes an HTTPS DNS record to advertise HTTP/3 support, enabling browsers to skip a round trip on the first connection by using QUIC immediately.

Iroh 1.0 is a stable release of a peer-to-peer networking library that uses cryptographic keys instead of IP addresses, enabling direct, secure connections across diverse transports and platforms.

Cloudflare details a bug in their QUIC implementation, quiche, where a Linux kernel optimization for CUBIC congestion control caused performance issues, and describes the resulting fix.

Researchers use QUIC backscatter from network telescopes to infer retransmission configurations of Google, Meta, and Cloudflare servers, revealing deployment details despite QUIC’s privacy aims.

quiche is a Rust-based implementation of the QUIC transport protocol and HTTP/3, providing a low-level API for processing QUIC packets and managing connections. It is used by Cloudflare for HTTP/3 support, Android's DNS resolver, and can be integrated into curl.

Iroh is a Rust library for peer-to-peer networking that simplifies connecting endpoints by public key, using hole-punching and QUIC with fallback relay servers, and provides composable protocols like blobs, gossip, and docs.
