Network Model For each layer of the OSI model, illustrate (through diagrams and text descriptions) the association of the scenario organization's network components (hardware and software) to the model layers. Name the hardware devices used at each layer as well as some protocols used at each layer. For example, at which layer is the router used? At which layer is the TCP protocol used? For each layer, include a discussion of how the components communicate between the layers. For each layer of the FCAPS (fault, configuration, accounting, performance, security), discuss the management function in detail and how the separation allows for the identification and allocation of the correct resources.
