Explanation

A layered protocol stack is designed to simplify network communication by separating functionalities into distinct layers. Each layer has a defined role and communicates with the layers directly above and below it. The main benefits of this model include: Simplified design and implementation: Developers can focus on one layer without needing to understand the entire system. Flexibility: New protocols can be developed and inserted at specific layers without redesigning the Interoperability: Standard interfaces allow different systems and vendors to work together. Isolation of functions: Errors and updates can be managed within one layer without impacting However, reducing protocol overhead is not a primary goal of this model. In fact, the encapsulation and interaction between layers can sometimes introduce extra overhead. This overhead is a trade-off accepted to gain the other benefits listed above.
