Open Source and Commercial Network Simulators

We will discuss about some fundamental concepts associated with network simulators, in this post. We will also attempt to distinguish some confusing crucial facets of network simulator which make uncertainty amongst readers.

Network simulation & simulator:

With the assistance of network simulation, any network can be modelled effortlessly. The fundamental idea of this model is to monitor the equivalent outcomes for evaluating configurations, performance, scalability, and various features of networking applications. Typically, it is extremely simple to study diverse set-ups at very low cost and try out networking changes instead of testing on a real network. However, network simulators aren’t perfect. They can’t ideally model the entire details of the networks. Nonetheless, if well simulated, they’ll be close enough so as to offer the researchers a significant understanding into the network under check, and how transformations will have an effect on its function.

Network simulators classified into diverse kind on the base of some norms such as they’re commercial or free, and they’re simple or complex.

Open source & commercial simulators:

Several network simulators are open sourced, which signifies that they’d offer the source code to its users for free. In such simulators the whole thing is open and everybody can contribute to it. There is no restriction on its interface, so it is also open for further enhancements. Due to its adaptability, new developments of latest technologies are done in a very quickly compared to commercial network simulators.

At the same time, the commercial network simulator signifies that they wouldn’t offer the source code of its application and the associated packages to its user, for free. To get its certified version users should have to disburse for total software, or they’ve to disburse exact packages that meet their exact usage needs. Commercial simulator has its advantages and disadvantages. The major benefit is that it supervised and sustained constantly by some professional staff of the organization, and it usually has comprehensive and updated documents. However, open-source simulator is unfavourable in this facet because there’re not adequate dedicated individuals working on its documents. This develops many serious issues when diverse editions come with several new things, and it’ll become more complicated to trace or comprehend the earlier codes without any appropriate documentation.

Overall, we can say for effective network management, network simulators are must have tools. Now, it depends on you which kind of network simulator you choose.

Key Features of Network Simulators

It’s very tough to set up a network in real-time for any testing the configuration of networking applications. To check a simple problem, it takes a huge amount of time and energy. So it’s not quite probable to setup the entire network in a real-time. There’re several tools, which assist network developers to check their network setups practically whether the networking application is capable of working in real-time environment. A network simulator is one of them. Simulators are employed for performance testing of networks and networking applications. With the assistance of simulation tools, both time & expenditure of testing the operations have been decreased and executions are made effortless. In this post, we will discuss about the main features and advantages of SNMP Simulator.

There are two common kinds of network simulation – one is employed on active networks and the other is employed prior to a network is assembled. The aims of these simulations are discovering issues or preventing them in the first place. Organizations can enhance network dependability and lower maintenance expenditures. In present time, the simulation is one of the most crucial technologies which imitate the real life and imaginary objects on computer.

The Network Simulator offers a versatile, integrated, easy-to-use GUI-based network designer tool to create and replicate a network with SNMP, Telnet/SSH, NetFlow, TL1, TFTP and DHCP.

The researchers use network stimulation to check different set-ups that aren’t simple to present in real-life due to its complexity and experiments. Network stimulators are extremely helpful, offering controlled and reproducible environment to check latest networking protocols or transform the active ones. Also, simulation tools are very handy to design diverse network topologies employing various kinds of nodes. Various people like network designers, academic researchers, software developers and quality assurances are employed to design, validate, imitate and examining the performance of diverse network protocols.

Usually, network simulator tools will comprise a wide variety of networking technologies and protocols which aids the user to develop complicated network from fundamental building blocks. You can effortlessly design diverse network topologies employing different kinds of basic building blocks like end host, hubs, mobile users, routers, network bridges and optical layer designs. These tools are used also to check and assess the effect of diverse parameters on the protocols being experiential.

Network stimulator tools are accessible with diverse features. Some of the network simulators are MIMIC Simulator, OPNET, REAL, OMNeT++, QualNet, MIMIC Virtual Lab and J-Sim.

Also, some NetFlow implementations permit the surveillance of packets on the egress IP interface, but this should be employed with care.
