- Each node is able to run several experiments simultaneously.
- An experiment runs in a given node as a sliver which holds a share of its
resources (CPU, memory, disk, bandwidth, interfaces…).
- Finally, related slivers are grouped in a slice for management purposes.
- All these concepts are inspired in PlanetLab. *##*
** Node architecture
allows the realization of these concepts. *##* A node consists of a CD, a RD
and a rD connected to the same wired local network.
- The community device
- Completely normal CN device, so existing ones can be used.
- routes traffic between the CN and the local network (which runs no routing
protocol).
- The research device
- Usually more powerful than CD, since experiments run here.
