Examples of notable network simulators / emulators include:Īre some commercial and open source code editable. There are both free/open-source and proprietary network simulators available. Thus it is as-if the real packet flowed through a real network but in reality it flowed through the simulated network.Įmulation is widely used in the design stage for validating communication networks prior to deployment. The simulation packet gets demodulated into a real packet after experiencing effects of loss, errors, delay, jitter etc., thereby transferring these network effects into the real packet. The real packet gets 'modulated' into a simulation packet. The typical methodology is that real packets from a live application are sent to the emulation server (where the virtual network is simulated). Live traffic can pass through the simulator and be affected by objects within the simulation. Network emulation allows users to introduce real devices and applications into a test network (simulated) that alters packet flow in such a way as to mimic the behavior of a live network. Most network simulators use discrete event simulation, in which a list of pending "events" is stored, and those events are processed in order, with some events triggering future events-such as the event of the arrival of a packet at one node triggering the event of the arrival of that packet at a downstream node. Trace files log every packet, every event that occurred in the simulation and is used for analysis. Further, drill down in terms of simulations trace files would also be available. Output results would include network-level metrics, link metrics, device metrics etc.

The network model/configuration describes the network (nodes, routers, switches, links) and the events (data transmissions, packet error, etc.). Most of the commercial simulators are GUI driven, while some network simulators are CLI driven. Simulators come with support for the most popular technologies and networks in use today such as 5G, Internet of Things (IoT), Wireless LANs, mobile ad hoc networks, wireless sensor networks, vehicular ad hoc networks, cognitive radio networks, LTE etc. In simulators, the computer network is modeled with devices, links, applications, etc., and the network performance is reported. Since communication networks have become too complex for traditional analytical methods to provide an accurate understanding of system behavior, network simulators are used.

The behavior of the network and the various applications and services it supports can then be observed in a test lab various attributes of the environment can also be modified in a controlled manner to assess how the network/protocols would behave under different conditions.Ī network simulator is software that predicts the behavior of a computer network. Most simulators use discrete event simulation in which the modeling of systems in which state variables change at discrete points in time. This is achieved by calculating the interactions between the different network entities such as routers, switches, nodes, access points, links, etc. In computer network research, network simulation is a technique whereby a software program replicates the behavior of a real network.
