Implementing TCP In Rust

🦊 Invisible low-latency P2P mesh VPN - silent to DPI, Reed–Solomon FEC loss-recovery, self-certifying mesh discovery, NAT hole-punching. What does the fox say? Nothing.

Educational MASQUE VPN implementation: CONNECT-IP protocol over QUIC/HTTP3 with REST API, comprehensive testing, and documentation for network protocol research

An experimental, kernel-bypass TCP/IP stack written in Rust. Features a hybrid threading engine and zero-copy architecture.

Network tunnel as an example

Userspace TCP/IP stack implemented from scratch in Rust over a TUN interface

Tcp Implementation in rust | RFC 793 | IPv4 | "a lot of TODOs left"

Userspace TCP/IP stack built from scratch in C — implements Ethernet/ARP, IPv4/ICMPv4, TCP handshake, data flow, and retransmission using a macOS utun virtual network interface. No libc networking — raw packet parsing all the way down.

User Space Network Stack implementation

A small userspace TCP stack experiment in Rust, built on a Linux TUN interface. The project parses IPv4 + TCP packets, tracks per-flow connection state, and crafts TCP replies in userspace.
