During the current laboratory lecture, the students are expected to learn about the next aspects: i) create an emulated host using the concept of Linux NameSpaces; ii) add, configure and enable the network interfaces on each host; iii) create a network link connecting two interfaces; iv) create a OpenvSwitch (OVS) that will be connecting the three hosts of the current topology; v) add to the switch the associated interfaces of the three network links previously created; vi) create the emulated topology by using a single script file; vii) specify on the switch traffic rules that match at distinct OSI layers; viii) test the current emulated topology; ix) remove from the system the visualized network infrastructure by using a second script file.

The current laboratory acting as a continuation practical session of the last week laboratory, it has the next main learning goals: learn how to create and remove an emulated network topology, using script files; learn how to emulate more realistic network conditions, such as latency and jitter, using the Linux tool Traffic Control (tc); and learn how the spanning tree protocol avoids loops within a local network.
