The Cisco Network Simulator & Router SimulatorThe 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.
 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.
Advantages of Software-Based Network SimulationBoson NetSim is a versatile tool and valuable asset, both in a classroom and for corporate use; it also provides a self-paced learning environment.
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 42 different router models and 6 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. We include simulation of Routers, Switches and PCs 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!
Advanced Features Included With Boson NetSim
*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 8.0.
NetSim for CCNP 8.0Boson NetSim for CCNP 8.0 includes labs created for the revised Cisco CCNP certification track. NetSim for CCNP 8.0 labs are organized to match the skills tested in the Cisco ROUTE (642-902), SWITCH (642-813) and TSHOOT (642-832) exams.
NetSim for CCNP 8.0 also contains a new and improved interface that makes completing labs, compiling new labs and designing network topologies easier than ever before.
