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

User Space Network Stack implementation

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.

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

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.

A userspace TCP/IP stack written from scratch in C++17: Ethernet, ARP, IPv4, ICMP, UDP and TCP (Reno congestion control, RFC 6298 adaptive RTO, out-of-order reassembly) running over a TAP device or a raw NIC, with no kernel sockets in the data path.
