Layered Network Architecture
To manage networking complexity, systems are structured into modular layers. In this model, each distinct layer performs a dedicated function and builds upon the capabilities provided by the layer immediately beneath it, enabling layers to be engineered and updated independently.

Learn After
In a modular layered network model, modifying or updating an individual layer requires re-engineering the entire network stack simultaneously.
An engineering team is planning to update an individual protocol layer in their network stack. Based on the principles of modular layered network architecture, explain how this update can occur independently. In your explanation, be sure to address:
- The overarching purpose of structuring network systems into modular layers.
- The functional dependency between the layer being updated and the layer immediately beneath it.
- Why the updated layer must continue to fulfill its dedicated function
