- Avoids problems with firewalls and private networks in nodes.
- Uses IPv6 to avoid address scarcity and incompatibility between CNs.
- Mgmt connections are short-lived to tolerate link instability.
- Gateways are entry points to the mgmt network.
- They help extend it over multiple CNs by external means (e.g. FEDERICA, the
Internet).
- They can also route the management network to the Internet.
- Researchers run experiments in slices spread over several nodes (as
slivers). *##*
** Slices, slivers and nodes
# Axel: Reverse, from PoV of researcher: select nodes, run as slivers, gruop in slices.
- These concepts are inspired in PlanetLab.
- A slice is a management concept that groups a set of related slivers.
- A sliver holds the resources (CPU, memory, disk, bandwidth, interfaces…)
allocated for a slice in a given node.
- A node hosts several slivers at the same time. *##*
** Node architecture
# Axel: More stress on node itself.
# Ivan: Don't zoom!!
allows the realization of these concepts. *##* A node consists of a CD, a RD
and a rD connected to the same wired local network. *##*

- Experiments are configured by researchers in the server and run in nodes. *##*
** Slices, slivers and nodes
- Particularly, researchers select nodes for running experiments.
- 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. *##*
