• Create a network reference model diagram of the current network that describes the role of each layer for both OSI and TCP/IP that are used to transmit data between the devices and applications specifically in your retail store.
• Create a revised network reference model diagram of the proposed network solution (using OSI or TCP/IP) that describes the hardware and software that are used to transmit data between the devices and applications in your retail stores.
• Based on the current dual-stacked network environment, create a data flow diagram for both OSI and TCP/IP that shows at least 4 typical network connections that are made by users in your retail store. Show how the data and information flow from the user workstation to the application using both the OSI and TCP/IP network models and the impact of encapsulation.
• Create a revised data flow diagram based on the proposed network solution that shows at least 4 typical network connections that are made by users in your retail store. Show how the data and information flow from the user workstation to the application using the chosen network model (using OSI or TCP/IP) and the impact of encapsulation.
• Provide an analysis as to how this part of the project fulfills the mission and 1 or more goals of the case study organization.
