- Link instability is tolerated by using short-lived mgmt connections.
- Gateways allow a testbed to span multiple CNs.
- Connecting the mgmt net over external means (e.g. FEDERICA, the Internet).
- Gateways can make the management network available to the Internet.
- A researcher runs the experiments of a slice in slivers each running in a
different node.
** Nodes, slices and slivers
# Diagram: Slices and slivers, two or three nodes with a few slivers on them,
# each with a color identifying it with a slice.)
- These concepts are inspired in PlanetLab.
- The slice (a management concept) groups a set of related slivers.
- A sliver holds the resources (CPU, memory, disk, bandwidth, interfaces…)
allocated for a slice in a given node.
** Node architecture
allows the realization of these concepts. A node consists of:
# Node simplified diagram, hover to interesting parts.
- The community device
- Completely normal CN device, so existing ones can be used.
- Routes traffic between the CN and the node's wired local network (which
