This is a community dedicated to all types of computer networking (physical/virtual/cloud/etc.)

Computers use common communication protocols over digital interconnections to communicate with each other. These interconnections are made up of telecommunication network technologies based on physically wired, optical, and wireless radio-frequency methods that may be arranged in a variety of network topologies.

Hi,

I would like to make some simple network simulations

I've tried to make run few (under Linux or Windows)

Kathara

GNS3

EVE-NG (3.1 GB ! to download )

omnetpp

ns-3

Cisco Packet Tracer (Not FLOSS, if I'm not mistaken )

The only one that I managed to install, run and use (set some nodes) was sadly the Cisco Packet Tracer ...

They other have their install process way to much complex or with such layer of dependency or more simply they way the works is too complex (running side VM for each nodes etc..) make it challenging to installing.

Do youn know a FLOSS Network Simulator , this is easy to install ?

Thanks.

Someone where I work set up a process to provision a VM with simulated devices & networking using containerlab. We use it to simulate scenarios and test the orchestration/automation software we develop. You declaritively define the nodes and connections, it's multi-vendor, and uses docker.

There's also clabernetes, which allows you to deploy the topology into a kubernetes cluster
