The Boson NetSim Network Simulator is an application that simulates Cisco Systems' networking hardware and software and is designed to aid the user in learning the Cisco IOS command structure. 

Cisco Network Simulator | NetSim NetSim utilizes Boson's proprietary Network Simulator, Router Simulator® and EROUTER® software technologies, along with the Boson Virtual Packet Technology® engine, to create individual packets. These packets are routed and switched through the simulated network, allowing NetSim to build an appropriate virtual routing table and simulate true networking. Other simulation products on the market do not support this level of functionality.

Boson offers a NetSim CCENT Network Simulator, CCNA Network Simulator and CCNP Network Simulator. Each supports the technologies and skills you will need for the respective certification.

Boson NetSim provides more versatility and support than any other network simulation software on the market. NetSim software also includes a comprehensive lab menu that contains lessons and labs covering routing protocols, Cisco devices, switching, topological design and much more.
