Socket Based File Transmission System

Comprehensive Project Report

The comprehensive report is in File Transmission System Design.pdf, that report has covered all the content of this project.

Build this project

The main class of this project is Sender class and Receiver, Please run both of these class to run this system.

• Sender class: The one who send files.
• Receiver class: The one who receive files.

Task Design

One the system is started, you can create many tasks, and add files to the task.

The task will run concurrently, since each task will run on a different thread.

In a task, you can add as many files as you need, files in the task will be sent linear.

Commands

• new Create a new Task.
• add Add a file to a Task.
• q Query the current Tasks.
• start Start a Task.
• startall Start all the Tasks.
• pause Pause a Task.
• resume Resume a Task.
