LiteSpeed QUIC (LSQUIC) Library is an open-source implementation of QUIC and HTTP/3 functionality for servers and clients. Most of the code in this distribution is used in our own products: LiteSpeed Web Server, LiteSpeed ADC, and OpenLiteSpeed. We think it is free of major problems. Nevertheless, do not hesitate to report bugs back to us. Even better, send us fixes and improvements!
Currently supported QUIC versions are Q043, Q046, Q050, ID-27, ID-28, ID-29, and ID-30. Support for newer versions will be added soon after they are released.
Documentation is available at https://lsquic.readthedocs.io/en/latest/.
In addition, see example programs for API usage and EXAMPLES.txt for some compilation and run-time options.
To build LSQUIC, you need CMake, zlib, and BoringSSL. The example program uses libevent to provide the event loop.
BoringSSL is not packaged; you have to build it yourself. The process is
straightforward. You will need go
installed.
- Clone BoringSSL by issuing the following command:
git clone https://boringssl.googlesource.com/boringssl
cd boringssl
You may need to install pre-requisites like zlib and libevent.
- Use specific BoringSSL version
git checkout 251b5169fd44345f455438312ec4e18ae07fd58c
- Compile the library
cmake . && make
Remember where BoringSSL sources are:
BORINGSSL=$PWD
If you want to turn on optimizations, do
cmake -DCMAKE_BUILD_TYPE=Release . && make
LSQUIC's http_client
, http_server
, and the tests link BoringSSL
libraries statically. Following previous section, you can build LSQUIC
as follows:
- Get the source code
git clone https://github.com/litespeedtech/lsquic.git
cd lsquic
git submodule init
git submodule update
- Compile the library
# $BORINGSSL is the top-level BoringSSL directory from the previous step
cmake -DBORINGSSL_DIR=$BORINGSSL .
make
- Run tests
make test
The library and the example client and server can be built with Docker.
Initialize Git submodules:
cd lsquic
git submodule init
git submodule update
Build the Docker image:
docker build -t lsquic .
Then you can use the examples from the command line. For example:
sudo docker run -it --rm lsquic http_client -s www.google.com -p / -o version=Q046
sudo docker run -p 12345:12345/udp -v /path/to/certs:/mnt/certs -it --rm lsquic http_server -c www.example.com,/mnt/certs/chain,/mnt/certs/key
The library has been tested on the following platforms:
- Linux
- i386
- x86_64
- ARM (Raspberry Pi 3)
- FreeBSD
- i386
- MacOS
- x86_64
- Android
- ARM
- Windows
- x86_64
Have fun,
