Comparison of commonly used computer network simulation software.

Simulation software	GS	PT	Dp	Np
Emulated network device	Routers, frame relay switches, etc.	Routers, switches, and wireless broadband routers	Router	Frame relay switches, network cards, etc.
Degree of simulation and disadvantages	Integration of simulation software does not support layer 3 switches	Software-based emulators that cannot be used in real-world environments	Has all the features of a real router but also interconnects with a real network	Fewer network devices are supported and are quite resource intensive
Applicable	Intermediate and advanced	Primary	Intermediate and advanced	Beginner, intermediate, and advanced
