What is the Three-Layer Hierarchical Network Model in Networking?
The Hierarchical Network Model is a networking architecture that categorizes an enterprise network into three distinct layers: the core, distribution, and access layers. This design model is beneficial for organizations as it formalizes the design and deployment of an enterprise-grade network and allows for easy scalability as networks grow.
The Core Layer, considered the network's backbone, uses extremely fast routers and switches designed to support extremely fast network traffic between different networks and pass data from the Core Layer to the Distribution Layer.
The Distribution Layer sits between the Core Layer and the Access Layer designed to provide routing, enforce access lists, and ensure that packets are routed to the correct subnet and VLANs.
The Access Layer serves as the architectural layer that supports network-connected endpoints such as servers and workstations. Further, organizations can implement access controls and policy definitions for how network-connect devices communicate at this layer.
