What is the difference between gns3 and Packet Tracer?

When talking about cross-platform network simulator tools, then there exist only a few names that have reached onto the level of Packet Tracer and GNS3. To the inexperienced eye, both the tools may look the same, and one can get confused between a comparison of GNS3 vs. Packet Tracer. You would find that several features make both cross-platform network simulator tools different and better from one another.

Yes, both of the programs simulate real-life network devices, computers, and various network connections to give us an ordered and simplistic view of what is happening in the backend. Both also make it possible for us to try configuring Cisco devices. However, they have their differences.

GNS3 or Graphical Network Simulator-3 is a unique software emulator that made it debut in the market in 2008. The differentiating feature of Graphical Network Simulator-3 emulator is to authorize a combination of real and virtual devices. This innovation makes sure that the user can simulate a seamless functioning of complex networks.

GNS3 is based on Qemu and Dynamips. It is just a graphical interface to make a virtual network using Qemu, and hence, you will need OS images for all devices you would like to use. For instance, you need an actual Cisco IOS image to use a Cisco device if you need a Linux/Windows image to emulate the computer. GNS3 uses Dynamips emulation software for thriving simulation of Cisco IOS.

On the other hand, Packet Tracer is a famous and successful cross-platform visual simulation tool that has been designed and produced by Cisco Systems. The Packet Tracer authorizes the users to build network topologies and also allows them to replicate new-age computer networks. With the aid of this software, users can simulate the complete configuration of Cisco switches and routers by adopting a simulated type command-line interface. 

Cisco Packet Tracer emulates the devices inside the program. In general, it already has built-in emulated computers, routers, switches, etc. You don’t need to prepare a real OS for it. But the device option is limited to a few Cisco routers and switches series. The computer doesn’t have many things to do like what you’d expect from a real-life one. It’s a rational choice if you don’t have any Cisco IOS image and want to learn how to use one. It also already supports popular routing protocols like RIP, OSPF, EIGRP, and BGP. You can also see what’s inside the network packet easily and how routers exchange packet, no Wireshark or tcpdump needed. All of that information can be seen visually. Simulation-based learning is vital to learn how to configure routers and switches from the command line for the students.

On top of that, Packet Tracer administrates drop problems and visual drag. This task is accomplished by virtual networking devices, which in turn helps demonstrate networking concepts. Guides can create their own self-evaluated assignments for the students.

So the addressing the final question Packet Tracer vs. GNS3, which is better? Both have their pros and cons, and we have taken into account almost all the vital features. 

So, the next time you select the network emulator tool, make sure to cross-check the features following your personal needs.

https://infotechtx.com/ not only has the latest version of Cisco Packet Tracer but also previous versions of the software if in case you have old system requirements. New files created from the latest version can no longer be used with older version software; however, the converse is true.
