HTTP3/QUIC Support

[triplewy]

Will Pingora integrate with Cloudflare Quiche to provide HTTP3/QUIC support? A quick look at the readme does not mention H3 or QUIC.

Pingora provides libraries and APIs to build services on top of HTTP/1 and HTTP/2, TLS, or just TCP/UDP. As a proxy, it supports HTTP/1 and HTTP/2 end-to-end, gRPC, and websocket proxying. (HTTP/3 support is on the roadmap.) It also comes with customizable load balancing and failover strategies. For compliance and security, it supports both the commonly used OpenSSL and BoringSSL libraries, which come with FIPS compliance and post-quantum crypto.

I find a quic library:https://github.com/quinn-rs/quinn. Does it make some help?

When we implement H3 support in pingora, we will do so using https://github.com/cloudflare/quiche

Hi,

I had a closer look into this topic and have done some proto-typing. Currently I'm thinking about taking the proto-type to a PR state or to leave it at where it is now.

Before starting I've looked into the various options around this area and in context of pingora.

Based on the available options the proto-type ended up having:

• a quiche/hyper-h3 integration
• and hyper-h3 integrated with pingora-core

This approach would allow to use quiche/quic in a BoringSSL/OpenSSL context and quinn/quic in a Rustls context while sharing the h1/h2/h3 integration. Having the disadvantage that the quiche/h3 layer is not used and having the advantage that the integration with current hyper based h1/h2 layer is quite straight forward.

The current status only involves the acceptor. As of now I've not looked into the connector. The quiche-h3 side is functional and pingora can be run with quiche-h3 & quinn-h3 on different endpoints to have a good option for performance comparisons.

For me it would be very helpful to understand if there is interest in the described approach before deciding on the way forward and/or adjusting the path.

Kind regards,
Harald
