Glossary¶
Topology¶
Contains everything to represent a virtual network (nodes, visual elements, links…)
Node¶
A Virtual Machine (Dynamips, IOU, Qemu, VPCS…) or builtin node (cloud, switch, hub…) that run on a compute.
Appliance¶
A model for a node used to create a node. When you drag an appliance to the topology a node is created.
Appliance template¶
A file (.gns3a) used to create a new node.
Drawing¶
A Drawing is a visual element like annotations, images, rectangles etc. There are pure SVG elements.
Adapter¶
A physical network interface, like a PCI card. The adapter can contain multiple ports.
Port¶
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.
Controller¶
The central server managing everything in GNS3. A GNS3 controller will manage multiple GNS3 compute node.
Compute¶
The process running on each server with GNS3. The GNS3 compute node is controlled by the GNS3 controller.
Symbol¶
A symbol is an icon used to represent a node on a scene.
Scene¶
A scene is the drawing area or canvas.
Filter¶
Packet filter, for instance to add latency on a link or drop packets
