A Layered Network model, such as the OSI model, is designed to organize the functions of a networking system into distinct layers, each responsible for specific aspects of communication. One of the main benefits of this approach is that it assists in protocol design. By segregating functions into layers, developers can focus on individual components without needing to understand the entire system's complexities, leading to more streamlined and efficient protocol development.
Another significant advantage of layered models is that they prevent one layer from affecting others. This means that changes or issues in one layer do not necessarily disrupt the functioning of adjacent layers, enhancing the stability and reliability of the network.
Moreover, the layered structure simplifies troubleshooting processes. When problems arise, technicians can isolate issues to specific layers, making it easier to identify and resolve faults without needing to analyze the entire network stack.
Increasing the number of connections is not a benefit associated with the layered model. In fact, while layered architecture enhances modularity and can facilitate easier integration of new technologies, it does not inherently lead to an increase in the number of connections; instead, it is focused on organizing and managing existing connections more effectively. Thus, understanding these distinctions clarifies why increasing connections is not a benefit of a layered network model.
