Title: Lab Exercise Five
Course: CNT 2001 Computer Networks & Communications > Section: Module 5 Network Protocols

Create a short essay (1 to 3 pages) that analyzes the progression of data as it passes down from the Application layer through the Transport layer, the Network Layer and the Data Link layer (you can assume Ethernet is in use on the Data Link layer).   Create a diagram that shows the encapsulation of data as each layer receives data from the layer above it.

In your analysis, provide an in depth discussion of the headers that are applied at each of the three layers (Transport, Network, and Data Link) that we are discussing in this activity.  Discuss the information that is added to the headers at each of the three layers that you are discussing.  Include the headers in your diagram.  Point out how the information that is in each of the headers will be used to route and deliver the data as it passes through routers and is finally delivered to its intended destination.

Include your references at the end of your essay.
