Like HW#3, the goal of this assignment is also to help you understand what is going on in the network by examining exactly what flows across a hop in the network. The traffic file is the same as used in HW#3. However, the focus of HW#4 is on the Transport and Application layers. You are expected to discover as much high-level information as possible.

Assignment Details

The goal of this assignment is to examine real protocols in use and understand the communication that takes place in a network by examining the bits that flow across a network hop. For this assignment, you should focus on the higher level protocols, i.e. pay more attention to the Transport and Application layers. The instructions for this homework assignment are identical to the instructions for HW#3. Clearly, you should refer to those instructions to refresh your understanding of the guidelines and requirements. The one difference is of course the focus of your investigation. Like HW#3, we have provided a set of questions to help guide you in the direction of the material that should be covered in the write-up. Questions include the following:

Assignment Turnin

The assignment should be submitted using the course web site. The file format must be either Micosoft Word (DOC) or Adobe Acrobat (PDF). Your report should be only one file (no zipping or taring files).
