## Background Apache Dubbo is a high-performance RPC framework dedicated to providing excellent service governance capabilities. With the introduction of HTTP/3, its features based on the QUIC protocol offer new possibilities for Dubbo microservices communication. HTTP/3, by reducing latency, increasing transmission speed, enhancing security, improving packet loss resistance, and supporting 0-RTT connections, provides significant performance and reliability improvements for Dubbo in cloud-native environments for microservices communication. ## Technical Solution Summary This proposal aims to integrate HTTP/3 into Apache Dubbo, supporting all core capabilities defined by the Triple protocol specification on HTTP/3. The construction of capabilities will revolve around the following core parts: 1. **Remoting Protocol Adaptation**: Develop a new remoting module based on netty-incubator-codec-http3, and modify dubbo-rpc-triple to make the existing triple's dependency on remoting compatible with HTTP/3. It also needs to include support for Alt-Svc defined in RFC7838 to implement bootstrapping. 2. **RPC Protocol Adaptation**: The adaptation of the RPC part includes both client and server. For the server, it mainly needs to support the initialization of HTTP/3 UDP Server, INPUT/OUTPUT adaptation, and the modification of TransportListener to support HTTP/3. The client part is mainly about supporting making call requests through HTTP/3, considering HTTP version negotiation, using HTTP/2 for servers that do not support HTTP/3, otherwise upgrading to HTTP/3. 3. **HTTP/3 Core Capabilities Support**: Based on the features of HTTP/3, support backpressure and flow control, support setting and optimizing congestion control algorithms, support frame prioritization. 4. **Performance Testing**: Conduct comprehensive performance testing, including comparison with HTTP/2 implementation and the original Dubbo protocol performance. The test report will cover key indicators such as machine load, response time, throughput under specific concurrency, latency, packet loss rate, and packet damage rate. <!-- Follow this checklist to help us incorporate your contribution quickly and easily: --> ## Checklist - [x] Make sure there is a [GitHub_issue](https://github.com/apache/dubbo/issues) field for the change (usually before you start working on it). Trivial changes like typos do not require a GitHub issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue. - [ ] Each commit in the pull request should have a meaningful subject line and body. - [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why. - [ ] Check if is necessary to patch to Dubbo 3 if you are work on Dubbo 2.7 - [ ] Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist. If the new feature or significant change is committed, please remember to add sample in [dubbo samples](https://github.com/apache/dubbo-samples) project. - [ ] Add some description to [dubbo-website](https://github.com/apache/dubbo-website) project if you are requesting to add a feature. - [ ] GitHub Actions works fine on your own branch. - [ ] If this contribution is large, please follow the [Software Donation Guide](https://github.com/apache/dubbo/wiki/Software-donation-guide). -- This is an automated message from the Apache Git Service.
