How to Write a New Git Protocol

This would have been very nice to have a few months ago! At Aspera we wrote a protocol handler for Git[1] that let us send data over fasp (a reliable UDP protocol for fast bulk-data transfers). I learned a ton by reading Git's source code to figure out how to do it, but this blog post is much more pain-free.

Very good write up!

That's very interesting! The alternatives to TCP that can be written in UDP which are optimized for a certain application are especially interesting to me. Working at the UDP level can present a lot of interesting performance options, kinda like working in C instead of Python.

Something I've been curious about is if there are proxies that can convert protocols. So for instance, on your local machine, you could have a proxy that turns TCP connections on port 8000 into FASP connections to another machine. This would let you use an ordinary web browser over FASP.

You could even pipe the proxies, e.g., TCP -> FASP -> MinimaLT [1]. That way any program could have really fast data transfer over an encrypted tunnel.
