The three-layer hierarchical model is a foundational framework commonly used to understand and design network topologies. This model breaks down the network into three distinct layers: the Core, Distribution, and Access layers. Each layer serves specific functions and responsibilities, facilitating efficient data flow and management across the network.

  • The Core layer is responsible for the high-speed transport of data across different networks and connecting to multiple distribution layers.
  • The Distribution layer acts as an intermediary, handling routing, filtering, and WAN access, while also performing Quality of Service (QoS) management for the traffic passing through.

  • The Access layer connects end devices to the network and controls user access.

This structured approach allows for scalability, easier management, and enhanced performance of a network, making it crucial for planning and operational efficiency. Understanding this model helps in designing robust networks that can support various services and applications effectively.
