network architecture

Network Architecture Paper: Using either the OSI Reference Model or the TCP/IP Protocol Suite, describe how each layer of the Model/Suite represents the communication flow between organizational levels and across departments/division of an actual hierarchical business, or communication to an external party outside the organization.  Be sure to include a communication flow diagram showing the logical and physical connections.

This is a scenario based assignment. I am not looking for definitions of the the various layers. Please describe a scenario such as sending an email, surfing the web, making a VOIP phone call, etc. that will use the 7 layers. Describe the scenario and how each layer fits into the overall communication process of the scenario.
