Architecture
============
GNS3 is splitted in four part:
* the GUI (project gns3-gui, gns3-web)
* the controller (project gns3-server)
* the compute (project gns3-server)
* the emulators (qemu, iou, dynamips...)
The controller pilot everything it's the part that manage the state
of a project, save it on disk. Onlye one controller exists.
The GUI display the topology. The GUI has only direct contact with
the controller.
The compute are where emulator are executed. If the compute is on
the same server as the controller, they are in the same process.
For each node of the topology will start an emulator instance.
A small schema::
+---------------+ +----------+ +------+
| | | COMPUTE +-----> QEMU |
| GNS3 GUI | +---> SERVER 1 | +------+
| QT interface +-----+ | +----------+
| | | | +---+
+---------------+ +v--------++ +--->IOU|
|CONTROLLER| | +---+
+---------+ +^--------++ +---------+ |
| GNS3 WEB+-----+ | | COMPUTE +--+
+---------+ +---> SERVER 2+--+ +--------+
+---------+ +--->DYNAMIPS|
+--------+
If you want to pilot GNS3 you need to use the controller API.
