NetSim
NetSim is a network simulation software that allows users to design, build, and test virtual computer networks. It provides a sandbox environment to prototype and test network configurations without physical hardware.
NetSim: Network Simulation Software
A network simulation software for designing, building, and testing virtual computer networks in a sandbox environment.
What is NetSim?
NetSim is a comprehensive network simulation software that enables users to model, simulate, and analyze the behavior of complex networks. It provides a virtual lab for modeling wired and wireless networks with configurable devices like routers, switches, firewalls, servers, and end-user systems.
Key features of NetSim include:
- Graphical drag-and-drop interface to design network topologies
- Extensive model library with 30+ pre-built network models
- Supports modeling of LAN, WAN, MAN infrastructures
- Simulation of routing protocols like OSPF, RIP, BGP
- Analysis of QoS parameters like throughput, delay, packet loss
- Comprehensive visualization tools to view packet flows and network traffic
- Troubleshooting of network congestion, errors, failures
- Programming tools to customize protocols and models
NetSim provides network administrators and engineers a scalable platform for testing new network designs, validating configurations, and gaining hands-on experience without access to physical devices. It can significantly reduce costs compared to deploying real test setups.
