The Advantages and Disadvantages of Protocol Layering?

Answer 1

Protocol layering offers several advantages, including modularity, which simplifies the development and maintenance of network protocols, and encapsulation, allowing for the isolation of changes within a specific layer without affecting others. However, it can also introduce inefficiencies, such as increased overhead due to multiple headers and processing delays as data passes through each layer. Additionally, the complexity of managing interactions between layers can lead to difficulties in debugging and optimization. Balancing these pros and cons is essential for effective network design.
