|Abstract: ||This project has been focused on the design and implementation of a hands-on laboratory, where students would be able understand and learn the different network protocols operations. Once dealt with the installation, we have done some tests focused on Wide Area Network emulation and, as a further step, the results have been analyzed and discussed.
In order to complete said tests, we have implemented some network traffic analysis tools, such as Traceroute, Ping or Wireshark. The latter in particular, due to its ease to capture, show and filter traffic from many different network protocols.
First of all, the theoretical basic concepts, essential to understand network protocols operation, have been properly described.
Then, once explained the theoretical fundamentals, the entire laboratory installation has been developed; starting with the hardware components assembly and then following with the software part installation. This second section also includes the setup of each service or protocol needed for the proper network operation.
Finally, in the last main section, tests performed in the laboratory have been detailed, once fully configured the network. These tests have been focused on Wide Area Network emulation through the WANem software tool, through which we have introduced some delays and packet loss into our network. At the same time, with the above mentioned network tools (Traceroute, Ping or Wireshark) we have tested protocols’ behaviour when experiencing these delays or packet loss.|
