Features

• Location-Based Image Display: Displays movie images from the CDN node nearest to the user's location.
• Movie Search: Users can search by movie name; if found, the image and details are displayed.
• Grid Layout Display: Movies are presented in a dynamic 3x3 grid layout, which adjusts based on available data.
• CDN Node Management: The CDNManager class efficiently handles CDN nodes and stores popular movies for quick retrieval.

Project Structure

The project is organized into the following components:

• WelcomeWindow: Displays the initial interface and collects user coordinates.
• ResultsPage: Shows movie images based on user location, allows searching, and updates based on the nearest CDN node.
• CDNManager: Manages the main server, CDN nodes, movie requests, and stores popular movies.
• Movie: Represents a movie object with properties such as name and poster image.
• CDNNode: Represents individual CDN nodes with coordinates and a cache of popular movies.
• MainServer: Central repository for all movies.

Setup

Prerequisites

1. Qt Framework: Download and install from Qt Framework for GUI support.
2. C++ Compiler: Requires a compiler compatible with C++11 or newer.
3. Filesystem Library: Requires C++17 for file handling.

Network Requirements

For optimal performance and stability, connect via LAN instead of WiFi when running the application.

Installation

1. Clone the Repository

   git clone https://github.com/OmChandraSharma/CDN_Optimization.git

2. Open All Project Files in Qt Creator
   • Launch Qt Creator and open all files within the CDN_Optimization folder to ensure all dependencies and components are loaded correctly.
3. Build the Project
   • In Qt Creator, select Build to compile the project.
4. Run the Project
   • After building, click Run to start the application and open the GUI for the CDN Server with Movie Searcher.

Usage

Initial Setup

1. Start the application to open the Welcome Window.
2. Enter your coordinates (X and Y between 0 and 200) and submit. These coordinates help calculate the nearest CDN node.

Viewing Movie Images

• The ResultsPage displays movie images based on your location, showing popular movies from the nearest CDN node in a 3x3 grid layout.

Search for a Movie

• Use the search bar to enter a movie name and search across CDN nodes. If found, the movie's image and details are displayed.

Classes and Components

• WelcomeWindow: Collects and validates user coordinates and connects inputs to ResultsPage.
• ResultsPage: Displays images from the nearest CDN node and includes a search bar.
• CDNManager: Manages CDN nodes and efficiently retrieves popular movies.
• CDNNode: Represents a CDN node with (x, y) coordinates and stores nearby popular movies.
• Movie: Defines movie properties, including name and image path.
• MainServer: Central repository for movies and manages image paths for retrieval.

Future Improvements

• Dynamic Node Allocation: Enable CDN nodes to adjust their cache based on recent user requests.
• Improved Search Functionality: Add fuzzy matching for flexible search results.
• Enhanced Image Caching: Implement advanced caching for frequently accessed images to improve performance.
