The Three Layers Of The Hierarchical Network Model

The Hierarchical Network Model is a roadmap for planning network deployment developed by Cisco. It's a network model that has been around for many years and is in widespread use. The Hierarchical Network Model is designed to implement deterministic networks that are reliable, scalable, and cost-efficient. Let's take a look at it.

This networking model generally consists of three layers:

  1. Core
  2. Distribution
  3. Access

The access layer is the edge of the network that is responsible for connecting host devices like smartphones and laptops. This layer requires the most attention and includes things like network discovery, security, application control like QoS, and the physical infrastructure like POE.

The distribution layer is like the highway of the network. It's responsible for moving traffic from point A to point B.

The core layer is the backbone of the network. It connects the various pieces of the distribution layers. This layer needs to be fast and reliable. It's the keystone of the network.

The complexity of each of these layers will depend on the size of the network.
