Cisco Packet Tracer

Cisco Packet Tracer is a powerful network simulation program that allows students to experiment with network behavior and ask “what if” questions. As an integral part of the Networking Academy comprehensive learning experience, Packet Tracer provides simulation, visualization, authoring, assessment, and collaboration capabilities and facilitates the teaching and learning of complex technology concepts.

Packet Tracer supplements physical equipment in the classroom by allowing students to create a network with an almost unlimited number of devices, encouraging practice, discovery, and troubleshooting. The simulation-based learning environment helps students develop 21st century skills such as decision making, creative and critical thinking, and problem solving.

Packet Tracer complements the Networking Academy curricula, allowing instructors to easily teach and demonstrate complex technical concepts and networking systems design. The software is available free of charge to all Networking Academy instructors, students, and alumni.

GNS3

GNS3 is a graphical network simulator that allows simulation of complex networks.


To allow complete simulations, GNS3 is strongly linked with :


* Dynamips, the core program that allows Cisco IOS emulation.
* Dynagen, a text-based front-end for Dynamips.
* Qemu, a generic and open source machine emulator and virtualizer.


GNS3 is an excellent complementary tool to real labs for network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP, CCIE, JNCIA, JNCIS, JNCIE.


It can also be used to experiment features of Cisco IOS, Juniper JunOS or to check configurations that need to be deployed later on real routers.


This project is an open source, free program that may be used on multiple operating systems, including Windows, Linux, and MacOS X.
