Call queuing is implemented in a telecommunications advanced intelligent network. At least two conducting elements are associated with the discharge and are movable relative to one another in that at least one of the conducting elements is movable under the effect of a drive mechanism. The first liquid phase includes one or more first flame retardants and an electrolyte. The attribute associated with the virtual application is then transformed into an attribute associated with a hypervisor-managed virtual machine, and this transformation of the attribute exposes the hypervisor-managed virtual machine associated with the virtual application such that the hypervisor-managed virtual machine is identifiable for backup.
