Embodiments provide systems and methods for managing resources in networks which utilize network slicing. Embodiments include systems and methods for monitoring performance in networks which utilize network slicing when the resources of a network domain are allocated to more than one slice. Embodiments include systems and methods for monitoring performance when resources of a slice are controlled by different network operators/service providers. A domain manager can make the performance measurement data available per network allotment instance with an identifier indicating to which virtual network service the performance measurement data belongs.
