# CDN Nodes

Content Delivery Nodes (CDNs) are the backbone of the dCDN architecture, responsible for managing and distributing digital content efficiently across a decentralized network. Each dCDN node is equipped with essential modules that enhance its functionality:

* **Content Storage Module**
  * Stores static and dynamic content, such as images, videos, and applications, ensuring quick access for users.
* **Data Processing Module**
  * Handles encoding, transcoding, and caching of content to optimize delivery based on user requests and network conditions
* **Load Balancing Module** 
  * Distributes incoming traffic evenly across multiple nodes, preventing overload on any single node and ensuring reliable performance.
* **Communication Module** 
  * Facilitates interactions between nodes and the overall network, allowing for the sharing of resources, status updates, and content availability.
* **Monitoring and Reporting Module**
  * Tracks performance metrics, such as latency, bandwidth usage, and error rates, to ensure high-quality service and enable proactive maintenance.
