The Problem
Simulating and understanding client-server protocols (HTTP, FTP, SMTP, socket streams) is difficult for students without low-level, direct protocol visibility and customization.
The Solution
Engineered socket-level TCP/UDP servers and clients in Python from scratch. Implemented reliable custom packet transfer logic, sliding-window flow control simulations, and mock mail/file transfer servers with a responsive desktop control panel.
Impact & Results
Created an effective educational testbed for network protocols, demonstrating low-level network performance differences and flow control principles.
