Hello!

Feel free to take a look at MsQuic (https://github.com/microsoft/msquic). It's written in C and is purely a QUIC implementation (no HTTP/3). We've not necessarily targeted it for embedded systems and I can't tell you off-hand how small the library will end up being in your scenario. If you try it out and find any specific problems, feel free to open issues and we can discuss fixing them.

Thanks,
- Nick

Subject: Small size of core QUIC library to replace TCP for embedded system

Hi,

I am looking for a slim backbone core QUIC library to replace TCP stack.

Here are core features currently I am using TCP, I am wondering if there is a QUIC open source library can be used or to be further developed to replace following TCP key functionality

- Replace Boost ASIO TCP by QUIC for socket communication between the device and Cloud services.

- Use (Address)-restricted-cone NAT

- Use TCP TLS

The major issue when I looked at Google and other QUIC source is because it supports HTTPS, the size is too large, it is not modularized, Some open source claimed the library can be used by adding or removing options, the reality is most of the QUIC libraries are designed based on HTTPS in mind, it is hard to have a clean small size QUIC core functions above.

I have to admit my knowledge about QUIC is limited, but I am a programmer, I am keen to participate a modular QUIC open source development for embedded system, here are options:

- Take an existing QUIC library (C/C++)

- Fork a QUIC Git source to develop a slim C/C++ QUIC for the embedded system.

- Start from scratch based on reference of some QUIC library

Appreciate your advice and suggestions.

Thank you.

Kind regards,

jupiter
