Advantages of Software-Based Network Simulation

Boson NetSim is a versatile tool and valuable asset for self-paced learning, classroom instruction and corporate training.
For many individuals, the availability of Cisco routers and switches is often limited. The cost and fragility of equipment makes rack rentals impractical at this level. Boson NetSim makes it possible to design and configure a network with 44 different router models and 7 different switch models* to choose from without having to pay a lot of money, or worrying about transporting and damaging valuable equipment.
NetSim's router, switch and station simulation components contained within the software are the most advanced in the industry. Within NetSim, simulation of routers, switches and PCs is included in a completely customizable drag-and-drop network-simulation package. Furthermore, Boson NetSim simulates both switching bridge tables and routing protocol tables to allow you to go OUTSIDE of the labs and create your own labs using the Boson Network Designer™.

NetSim Network Simulator, Router Simulator and Switch Simulator

The Boson NetSim™ Netowork Simulator™ is an application that simulates Cisco Systems'® hardware and software. NetSim is designed to help you learn the Cisco IOS® command structure focused around the Cisco certification tracks. 
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 approporiate virtual routing table and simulate true networking. Other simulation products on the market do not support this level of functionally. Boson NetSim provides the most versatility and support in the market. NetSim software also includes comprehensive labs covering the technologies and topics that are covered on the corresponding certification.
*Although all devices can be added to a custom topology, the commands needed to configure some devices are restricted depending on the license version. For example, 3550 switches can be added to a CCENT or CCNA custom topology. However, the commands needed to configure a 3550 switch are only supported in NetSim for CCNP.
