ABSTRACT
In the previous chapter, we discussed the concept of network
emulation in general, and how it is different from other experiment
techniques. Now let us give an overview of the network emulation
tools that are available for use. You will see that there are almost 30
such relatively well-known tools and environments. Following the
overview, we shall provide several criteria and use them to classify
the presented emulators. This should help our readers put some
order in the emulatorworld andmake it an easier task for them if the
need to choose and use a network emulator appears at some point
in their career.
