Your Network, Replicated — Test Before You Deploy
Hierarchical topology generation with 12+ device translators. Build digital twins of enterprise networks using VyOS, pfSense, Cisco, Juniper, and Arista device models.
Why This Matters
Network changes in production are risky. Configuration errors cause outages, and testing in production is not an option for critical infrastructure.
Building test environments that accurately replicate production networks is manual and time-consuming. Multi-vendor environments with complex routing are especially difficult to simulate.
Network training requires expensive physical equipment or vendor-specific simulators. Organizations need a cost-effective way to build realistic multi-vendor lab environments.
NetSim
NetSim generates hierarchical network topologies with 12+ device translators for VyOS, pfSense, Cisco, Juniper, Arista, and more. Creates digital twins of production networks for testing, training, and validation. Multi-cloud abstraction with VXLAN segmentation.
Key Capabilities
12+ Device Translators
VyOS, pfSense, Cisco IOS, Juniper JunOS, Arista EOS, and more. Multi-vendor topologies with realistic configurations.
Hierarchical Topologies
Core → Distribution → Access layer generation. Enterprise-grade routing with OSPF, BGP, VXLAN.
Digital Twin Generation
Replicate your production network as a virtual twin. Test changes, train staff, validate before deploying.
Multi-Cloud Abstraction
Deploy network topologies across OpenStack, AWS, or VMware. Same topology definition, any cloud target.
VXLAN Segmentation
Per-tenant network isolation using VXLAN encapsulation. Test multi-tenant scenarios safely.
Configuration Export
Export device configurations for deployment. Test in NetSim, deploy the same config to production.
Use Cases
Real-world scenarios where NetSim delivers measurable impact.
Network Change Validation
Scenario: A telecom operator needs to validate a BGP configuration change before deploying to production routers.
Outcome: NetSim builds a digital twin of the production routing topology. The change is tested in the twin, validated against traffic patterns, and deployed with confidence.
Network Engineering Training
Scenario: A training institute needs multi-vendor lab environments for CCIE/CCNP preparation courses.
Outcome: NetSim generates realistic Cisco + Juniper + Arista topologies on demand. Each student gets an isolated environment. No physical equipment costs.
Data Centre Migration Planning
Scenario: An organization is migrating from a traditional 3-tier network to a spine-leaf architecture.
Outcome: NetSim models both the current and target architectures. Engineers validate routing, failover, and performance before the migration window.
