CASE FILE / COMP3331 / Computer Networks
Socket-Based Client–Server ApplicationDesigning an Application Protocol over TCP/IP
Implemented a networked Python client–server application using low-level socket programming, authentication and structured command exchange.
01–02 / OPENING SEQUENCE
Establishing the world
01 / Establishing Shot
The Problem
Independent client processes needed to communicate reliably with a central server while sharing application state through an explicitly designed network protocol.
02 / Wide Shot
The Context
The project formed part of COMP3331 and focused on applying networking concepts through low-level Python socket programming.

Role notes
DIVAKAR DESSAI
I implemented the client, server and communication protocol, including authentication, command parsing and shared state handling.
04 / CLOSE-UP
THE ENGINEERING CHALLENGE
Operations that would be simple local function calls instead had to be represented as network messages and remain correct despite invalid requests or disconnected peers.
05 / TRACKING SHOT
THE APPROACH
A plan emerges.
I designed a request-response protocol on top of sockets, serialising client commands, validating them on the server and returning structured responses.
06 / INSERT SHOTS
KEY FEATURES
The system takes shape.
07 / DIRECTOR'S NOTES
DESIGN DECISIONS
Things we decided along the way
01
Centralised shared state on the server.
02
Separated client command parsing from server-side validation.
03
Used explicit protocol messages to coordinate independent processes.

WHAT WENT WRONG
Naturally, not everything cooperates.
09 / FINAL SHOT
THE OUTCOME
ProblemBuildOutcome
01
Built a functioning networked application using low-level sockets.
02
Applied TCP/IP concepts beyond theoretical packet analysis.
03
Developed practical experience designing application-layer protocols.
