# TCP and UDP hole punching experiments

This is the code I wrote (or copied and modified) during the research I did for implementing multiplayer in my game. 

## Sources I used

### Protobuffs

Useful for defining custom message formats (with automatic serialization into binary and json).

https://developers.google.com/protocol-buffers/docs/tutorials

### Hole Punching

A must read paper that actually made sense. Includes info on NAT routers, describes UDP and TCP hole punching AT LENGTH:

https://bford.info/pub/net/p2pnat/

Python code people wrote based on that paper. It's not ideal, but serves as reference.

### UDP

UDP hole punching explanation:

https://stackoverflow.com/a/11377330/9731532

UDP hole punching implementation:

https://stackoverflow.com/a/53215243/9731532

I also cleaned up that code a little bit, see `UDP_StackOverflow`.

My simplified implementation, see `UDP_My_Test`.

### TCP

Mostly used the aforementioned paper and the python code as reference.

How To TCP NAT Traversal. A simple technique with a not self hosted relay server is presented. Note that hosting a relay server is not a problem in my case.
