Contains everything to represent a virtual network (nodes, visual elements, links…)

A Virtual Machine (Dynamips, IOU, Qemu, VPCS…) or builtin node (cloud, switch, hub…) that run on a compute.

A model for a node used to create a node. When you drag an appliance to the topology a node is created.

A file (.gns3a) used to create a new node.

A port is an opening on a network adapter where can be plugged into.

For example a VM can have a serial and an Ethernet adapter. The Ethernet adapter itself can have 4 ports.

The central server managing everything in GNS3. A GNS3 controller will manage multiple GNS3 compute node.

The process running on each server with GNS3. The GNS3 compute node is controlled by the GNS3 controller.

A symbol is an icon used to represent a node on a scene.

A scene is the drawing area or canvas.

Packet filter, for instance to add latency on a link or drop packets
