Two main reasons for using layered protocols are: 1) Modularity and Independence: Each layer performs a specific function, making it easier to design, develop, test, and maintain the system. Layers can be changed or upgraded independently without affecting other layers. 2) Error Control and Flow Control: Each layer can handle errors and control data flow within its own layer, allowing for better error correction and more efficient communication.
