Please make sure to provide reasonable details on
the kind of traffic, and copyrights if relevant.
Do not provide bogus information; if a complaint is lodged against
your slice and your PlanetLab Operations Center is unable to determine what the normal behavior
of your slice is, your slice may be deleted to resolve the complaint.

There are four possible "instantiation" states for a slice.
PLC instantiated slices can be defined as OMF friendly, in which case slivers come with the OMF Resource Controller pre-installed and pre-configured. Such slivers can then be easily managed through a centralized tool, the OMF Experiment Controller. Using these OMF tools, a user can describe, instrument, and automatically execute their experiments across many slivers. Please refer to the OMF User Guide to learn more on how to use this feature.
