Hands-On Network Programming with Modern C++

Build Real-World Network Applications with Modern C++

Most networking books teach APIs. This book teaches engineering.

If you want to build scalable servers, secure clients, REST APIs, real-time communication systems, or distributed applications in modern C++, this practical guide will take you from networking fundamentals to production-grade systems used in professional environments.

Rather than focusing on isolated code snippets, you'll build complete networking applications while learning the principles that drive modern software architecture.

What You'll Learn

Networking Fundamentals

How the Internet actually works TCP/IP architecture IPv4 and IPv6 DNS, routing, and packet flow Latency, throughput, and performance metrics

Socket Programming

Berkeley Sockets API TCP and UDP communication Connection management Non-blocking sockets Cross-platform networking for Linux, Windows, and macOS

High-Performance Networking

select(), poll(), epoll(), kqueue(), and IOCP Event-driven architectures Thread pools and worker queues Asynchronous programming with Boost.Asio Performance optimization techniques

Application Protocols

Designing custom protocols Message framing Serialization and deserialization HTTP and REST APIs WebSockets gRPC and Protocol Buffers

Security

TLS and OpenSSL Certificate management Authentication and authorization Secure coding practices Common network attack vectors

Production Engineering

Wireshark and packet analysis Debugging network applications Logging and observability Docker deployment Performance benchmarking

Build Real Projects

Throughout the book, you'll develop complete working applications including:

✓ TCP chat systems

✓ UDP telemetry platforms

✓ Multithreaded servers

✓ Event-driven network services

✓ HTTP web servers

✓ REST APIs
