GNS3 expose two type of endpoints:

  • Controller
  • Compute

Controller API Endpoints

The controller manage all the running topologies. The controller has knowledge of everything on in GNS3. If you want to create and manage a topology it’s here. The controller will call the compute API when needed.

In a standard GNS3 installation you have one controller and one or many computes.

Compute API Endpoints

The compute is the GNS3 process running on a server and controlling the VM process.


Consider this endpoints as a private API used by the controller.
