·         Observe how the TCP flags are used for the application exchanges.


Format of Experiments - The lab instructions include the following:

·         Objectives – What does the student learn from the experiment.

·         Network Setup – Network and device configurations for the experiment.

·         Procedure – Steps to perform the experiment.

·         Report – Answers to the questions in the Procedure section and results.


Student Lab Report

·         For each experiment, it is expected each student writes a report to:

o    Answer questions in the instruction sheet.

o    Explain her/his observations from the experiment.

o    Analyze the results collected from the experiment.


·         Your report should be presented in MS Words.

o    Not more than 4 pages
