With GENI, we can ask for links between resources, such as VMs. These appear as network interfaces on the VMs. If a VM has more than one link, it is important to note the network interface belonging to each link. This can be done by observing the unique IP subnets GENI assigns to each link. In our simple topology, we have two links – one between host-1 and switch and another between host-2 and switch.
