# Network Numbat

![Haskell CI](https://github.com/lancelet/numbat/workflows/Haskell%20CI/badge.svg)

> Learning how the Network of Tubes works

This project is not intended to implement any "real-world" functionality.

Instead, it's my personal learning about the network stack.

## Implemented Features

- [ ] Encoding / decoding TCP header

- [ ] Encoding / decoding IP segments

- [ ] TCP state machine

## Sources of Documentation

- [RFC 793][rfc-793]: The main TCP RFC.

- [TCP at Wikipedia][tcp-wikipedia]: Extra summary of background information.

- [`tcpdump` Cheatsheet][tcpdump-cheatsheet]: Useful summary of `tcpdump`

  options.

- [`rust_tun`][rust-tun]: A Rust binding for TUN which works on MacOS.

- [`mac-utun`][mac-utun]: Another Rust TUN binding for MacOS.

- [WWDC Presentation on DriverKit][wwdc-driverkit]: DriverKit allows user-space

  macOS drivers. Maybe even a TAP (layer 2 virtualisation) implementation.

- [WWDC Presentation on Network Extensions][wwdc-network-extensions]: I think 

  this is more background on DriverKit, etc.

- [NetworkingDriverKit][networkingdriverkit]: A sub-component of DriverKit,

  for Ethernet drivers.
