In the arena of network research, it’s extremely expensive to organize a comprehensive test bed including multiple networked routers, data links and computers to authenticate & verify a specific network algorithm. In these situations network simulators saves time and money in completing this job. Also, network simulators are mainly helpful in allowing network designers to try various network applications’ features or modify the configurations in a reproducible and controlled manner.

Network simulators are utilized by people from diverse areas such as Quality Assurance, industrial developers and academic researchers to blueprint, simulate, verify & evaluate the performance of various parameters of networking applications. With network simulator assistance, user can design diverse network topologies using different kinds of nodes like:

• End-hosts, hubs

• Routers

• Network switches

• Firewalls

• Lan/WAN links

• Hubs

Network simulation & simulator:

Normally speaking, network simulators endeavor to replicate the real world network. The main proposal is that if a structure could be modeled, the aspects of the model could be transformed and the equivalent results could be evaluated. As the procedure of model adjustment is considerably affordable compared to the absolute real execution, a wide range of scenarios could be evaluated at low price.

MIMIC IOS Simulator fully supports Cisco IOS® software and SNMPv1, v2, v2c, v3. You can simulate up to 100,000 devices in a single workstation, and an unlimited number of devices can be simulated by distributing it over multiple workstations. You can access devices using Telnet, SSH and SNMP. Changes made using one protocol is reflected in other. You can test applications using hundreds of simulated Cisco IOS commands. Along with that MIMIC CLI/IOS Recorder allows you to record any command and simulate it.
