This article explains the limitations of TCP and UDP for real‑time applications, introduces the KCP protocol as a UDP‑based solution that combines reliability with low latency, outlines its features, working principles, code usage, and real‑world deployment examples in gaming, video conferencing, live streaming, and IoT.
This article explains the shortcomings of TCP and UDP for latency‑sensitive applications, introduces the KCP protocol as a reliable yet low‑latency UDP‑based solution, outlines its key features and operation, and provides practical code examples for integration.
This article details the design and implementation of a self‑developed interactive live‑streaming platform that supports massive concurrent users and ultra‑low latency for online education, covering business scenarios, technical abstractions, key low‑latency and high‑concurrency techniques, and real‑world performance results.
This article presents a Kotlin compiler plugin that replaces verbose annotation‑based serialization with delegate‑based syntax, dramatically improves code readability, reduces boilerplate, and achieves up to 20% faster compilation while providing detailed implementation steps, performance results, and practical guidelines.
This article presents a Kotlin compiler plugin that replaces verbose annotation‑based serialization with concise delegated properties, explains its design and implementation details, demonstrates significant compilation‑time reductions of up to 20% and cleaner code, and provides a step‑by‑step guide for developers interested in building similar compiler extensions.
This article describes the motivation, requirements, solution research, and detailed design of a lightweight distributed VPN built with Go, employing KCP as the transport protocol, and includes prototype source code for both hub and peer components.
