Noq: n0's new QUIC implementation in Rust

4 hours ago

Announcement of noq (number 0 QUIC), a general-purpose QUIC implementation with multipath and NAT traversal support.
Originally forked from Quinn due to architectural mismatches and specific needs of iroh.
Transition from soft fork to hard fork to allow deeper structural changes without burdening Quinn maintainers.
Key features include QUIC Multipath, NAT traversal, and QUIC Address Discovery (QAD).
Multipath implementation allows QUIC to manage multiple paths (relay, direct IPv4, IPv6) as first-class concepts.
NAT traversal implementation is robust and production-grade, improving reliability and congestion awareness.
QAD replaces STUN for discovering public IP addresses, enhancing privacy and preventing protocol ossification.
Extended QLog support for better debugging and visualization of QUIC connections, including multipath events.
Introduction of WeakConnectionHandle for managing connections without keeping them alive unnecessarily.
noq has been in production since iroh v0.96, with interoperability tests against picoquic.
Future plans include further NAT traversal improvements and performance optimizations enabled by multipath.
Invitation for collaboration with those working on QUIC implementations, p2p transport, or diverse network applications.
