Strengths and trade-offs
Cisco Modeling Labs — where it wins
- Cisco and third-party images with browser-based lab management
- REST APIs, Python automation, and integrations with pyATS, Ansible, and Terraform
- Clustering, external connectivity, Wireshark streaming, Docker, and KVM support
Where it doesn't
- Personal and Personal Plus are single-user plans with fixed node capacity
- CML Cloud Phase 1 is an invite-only proof of concept
- It does not emulate physical hardware or act as a discrete-event simulator
ns-3 — where it wins
- Free and open source for research and education
- Broad wireless, IP, routing, mobility, and device models
- Real-time, tracing, visualization, and MPI support
Where it doesn't
- Desktop deployment without a web interface
- Scenario development uses C++ or Python programs
- Integrations are limited to a focused set of tools
- Cisco Modeling Labs9.2/10 · Free plan
