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 the wire. The traffic file is the same as used in the 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.
The goal of the 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 segment. 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 material. Like HW#3, we have provided a set of questions to help guide you in the direction of the material we expect to be covered in the write-up. Questions include the following:
All instructions regarding formatting and submission instructions are the same as for HW#3. The only differences are the due date and the turnin assignment number. This assignment is due by December 1st at . Late submissions will not be accepted. To summarize, the turnin instructions are as follows:
Submit the assignment in HTML format as a single file. Do not forget to include your email, name and Perm#. Your HTML file should be named using the following convention: <firstname-lastname>.html, for example kevin-almeroth.html
