Open Source Java KCP Software

java-Kcp is a Java implementation of the KCP reliable UDP protocol built on top of Netty. It is designed for applications that need fast, reliable communication over UDP, especially games, video systems, and network acceleration services. The project includes forward error correction support and aims to remain compatible with other KCP implementations, including C, Go, and a related C# version. Its documentation provides server and client examples, usage parameters, best practices, troubleshooting notes, and performance testing information. The library is positioned as stable enough for real projects and has been used in online production scenarios. It is useful for Java backend developers who need low-latency network transport without giving up reliability features.
