Go Network Programming - TCP, UDP & HTTP Labs

A practical repository for understanding network services from the protocol level upward.

Problem

Backend engineers can use frameworks quickly, but protocol behavior is easier to reason about after writing clients, servers, deadlines, and handlers directly. This project makes those mechanics concrete through small Go networking labs.

Architecture

The repository is organized as focused experiments: TCP clients and servers, UDP message exchange, HTTP handlers, concurrency patterns, and observability hooks. Each lab isolates one networking concept while keeping enough structure to compare behavior.

Technologies

• Go standard library networking primitives.
• TCP and UDP client/server examples.
• HTTP server patterns, routing, deadlines, and structured responses.
• Concurrency patterns using goroutines, channels, and bounded work.

What I Built

• Client/server examples for basic transport-layer behavior.
• Timeout-aware request handling to avoid hanging network operations.
• Small experiments for concurrency, worker routines, and request flow.
• Notes that connect low-level protocol behavior to backend service design.

What I Learned

• Timeouts, cancellation, and backpressure are not extras; they are core network behavior.
• Small protocol experiments make production backend choices easier to justify.
• Measuring before optimizing prevents misleading performance assumptions.

Future Improvements

• Add reproducible benchmarks for concurrent client scenarios.
• Add packet captures and short notes explaining each protocol exchange.
• Extend the labs with TLS, HTTP/2, and gRPC comparisons.
