    5656 Slices::
    57   From a researcher's perspective, a ''slice'' is a substrate-wide network of computing and communication resources capable of running an experiment or a wide-area network service.  From an operator's perspective, slices are the primary abstraction for accounting and accountability—resources are acquired and consumed by slices, and external program behavior is traceable to a slice, respectively.  A slice is the basis for resource revocation (i.e., shutdown).  A slice is defined by a set of slivers spanning a set of network components, plus an associated set of users that are allowed to access those slivers for the purpose of running an experiment on the substrate. That is, a slice has a name, which is bound to a set of users associated with the slice and a (possibly empty) set of slivers.
