Graphical Network Simulator-3 (shortened to GNS3) is a network software emulator first released in 2008. [2] [3] [4] It allows the combination of virtual and real devices, used to simulate complex networks. It uses Dynamips emulation software to simulate Cisco IOS. [2]: 55 [5]
ns-3 is a discrete-event network simulator, sometimes called a 'system simulator' in contrast to a 'link simulator' that models an individual communications link in more detail. ns-3 is written in C++ and compiled into a set of shared libraries that are linked by executable programs that describe the desired simulation topology and configuration.
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks.The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Dynamips is an emulator computer program that was written to emulate Cisco routers.It was developed by Christophe Fillot, who began working on it in August 2005. Dynamips runs on FreeBSD, Linux, Mac OS X and Windows.
In computer network research, network simulation is a technique whereby a software program replicates the behavior of a real network. This is achieved by calculating the interactions between the different network entities such as routers, switches, nodes, access points, links, etc. [1] Most simulators use discrete event simulation in which the modeling of systems in which state variables ...
Mixed-mode simulation is handled on three levels; (a) with primitive digital elements that use timing models and the built-in 12 or 16 state digital logic simulator, (b) with subcircuit models that use the actual transistor topology of the integrated circuit, and finally, (c) with In-line Boolean logic expressions.
