This article presents a step-by-step guide to implementing a TCP server in Linux, starting from a simple single-connection model and evolving to a thread-pool-based architecture for handling high concurrency. The author covers key concepts such as socket creation, binding, listening, and accepting connections, then introduces threading and thread pool management to improve scalability. The tutorial is code-heavy but well-structured, making it suitable for developers who want to understand the fundamentals of network programming in a Linux environment. While the content is not groundbreaking, it serves as a solid refresher or learning resource for those new to systems programming. The thread pool implementation is particularly relevant for building efficient server-side applications.
This tutorial walks through building a high-concurrency TCP server in Linux using socket programming and thread pools. It provides a practical progression from basic to advanced patterns, making it a useful reference for backend engineers.
