Cisco Packet Tracer

Cisco Packet Tracer is a software and visual simulation tool that allows users to create network topologies and replicate modern computer networks. By practicing a command-line interface, it will enable the users to configure Cisco routers and switches.

It can work on operating systems like Linux, android 4.2, MS Windows, and iOS 8, etc. It provides visualization, simulation, authoring, evaluation, and association competencies to facilitate teaching and learning of different complicated technology concepts.

The simulation model can provide tables, diagrams, and other visual representations of dynamic data transfer and the development of packet content. By using real-time visuals, users can replace the whiteboards and fixed slides and can decrease presentation time.

One of the prominent features is that it has two workspaces. The logical workspace allows the users to build logical network topologies by connecting network devices, and the physical workspace provides a graphical and physical aspect of the logical network.


Cisco Packet Tracer Alternatives

#1 Virtual PC Simulator


Virtual PC Simulator is an open-source software running on Linux and Windows, where only limited network commands can be used. It is an ideal tool to use in simulated networks such as GNS3 as it has developed from a simple to a robust testing ACLs tool. Because of the detailed output of ping replies and commands such as to see packet dumps, etc., made it a toolkit for the networking engineers.

Virtual PC Simulator simulates up to 9 PCs, and it is more useful than traditional PCs because it can send and receive UDP and TCP pings. From the virtual PCs, you can ping or trace out the other routers or hosts when you learn the Cisco routers in the Dynamips. It can substitute the routers or VMware boxes used as PCs in the Dynamips network.

When it starts, it attends the ports from 2000 to 2008 and delays the dynamips to connect and sends the packets to the ports from 3000 to 3008, which would be accompanied by the dynamips.


#2 Router Configuration Generator Tool
