Pros:
1. Simplification: Combining the three layers into one can simplify the networking architecture and reduce complexity. It would streamline the communication process and make it easier to understand and implement applications.
2. Reduced Overhead: With fewer layers, there would be less encapsulation and de-encapsulation overhead, leading to more efficient data transfer.
3. Faster Communication: The reduced number of layers can potentially lead to faster communication between applications since there are fewer intermediaries.
