Simplified Distributed File System

Objective:

Design and implement a simplified distributed file system in Java using TCP sockets. This system will allow clients to store, retrieve, and manage files across multiple servers.

Components:

$1.$ FileServer:

$-$ Listens for incoming connections from clients.

$-$ Handles file operations $($create$,$ read, write, delete$).$

$-$ Maintains a local file system.

$2.$ FileSystemClient:$|$

$-$ Connects to a file server.

$-$ Sends file operations requests to the server.

$-$ Receives file data or error messages from the server.

Data Structures:

$-$ Use a simple list or array to store information about available file servers.

Protocol:

$-$ Design a custom protocol for communication between clients and servers.

$-$ Include commands for file operations $($create$,$ read, write, delete$).$

Additional Features:

$-$ Support different file types $($e$.$g$.,$ text, images, binary$).$

Deliverables:

$-$ Java code for the FileServer and FileSystemClient classes.

$-$ Documentation explaining the system architecture, protocol, and data structures.

$-$ Test cases to evaluate the system's functionality and performance.

Test cases:

FileServer:

$-$ Test file creation with valid and invalid filenames.

$-$ Test file reading for existing files of different sizes and types.

$-$ Test file writing with different content.

$-$ Test file deletion for existing and non$-$existent files.

$-$ Test error handling for network failures, file system errors, and invalid commands.

FileSystemClient:

$-$ Test connection to the file server.

$-$ Test sending and receiving valid file operations requests.

$-$ Test error handling for invalid commands or server errors.
