Key Features

• Location-Based Display: Fetches and displays movie images from the CDN node closest to the user's input coordinates.
• Search Functionality: Allows users to search for movies by title, returning relevant images and information if found.
• Responsive Grid Layout: Presents movies in an adaptive 3x3 grid layout that adjusts according to the number of available entries.
• Efficient CDN Handling: The CDNManager class oversees CDN nodes and ensures fast access to frequently requested movies.

Project Layout

The project is divided into the following components:

• WelcomeWindow: Initial interface for entering user coordinates.
• ResultsPage: Displays search results and movies based on the closest CDN node.
• CDNManager: Oversees server operations, node communication, and popular movie caching.
• Movie: A data class for movie details including title and image.
• CDNNode: Represents individual CDN nodes with geographic coordinates and a cache of popular movies.
• MainServer: Houses the complete movie database and handles image path requests.

Installation Guide

Requirements

1. Qt Framework: Download from Qt's official site to support the graphical interface.
2. C++ Compiler: Use a compiler that supports C++11 or later.
3. C++17 Support: Ensure filesystem operations are compatible with C++17.

Network Tip

For smoother performance, especially during data transfers, connect via LAN rather than WiFi.

How to Use

Startup Process

1. Launch the application and enter your coordinates (values between 0 and 200).
2. These inputs are used to determine your nearest CDN node.

Browsing Movies

• The application will display a 3x3 grid of popular movie images from your closest node.

Searching for a Movie

• Use the integrated search bar to find a movie by title. If available, the movie image and info will be shown.

Core Classes and Components

• WelcomeWindow: Handles user input for coordinates and connects to the result view.
• ResultsPage: Shows movie posters from the nearest node and supports search functionality.
• CDNManager: Controls all CDN operations and optimizes data access.
• CDNNode: CDN nodes defined by (x, y) location and a list of nearby popular movies.
• Movie: Contains the movie name and image location.
• MainServer: Central source for all movies and their corresponding images.

Planned Enhancements

• Dynamic Caching Strategy: Allow CDN nodes to adapt their caches based on trending requests.
• Fuzzy Search: Improve the search experience by allowing partial or typo-tolerant matches.
• Advanced Image Caching: Optimize image loading and performance through intelligent caching mechanisms.
