mapping the network resource isolation policy to a network resource allocation policy comprising isolation related requirements of virtual and/or physical resources for a network service; and
sending the network resource allocation policy relating to the physical resources to a network function management function (NFMF) and/or the network resource allocation policy relating to the virtual resources to a network function virtualization management and orchestration (NFV-MANO) function for instantiation of the network service; and

in a case where the NSS isolation policy comprises the application level isolation policy:
mapping the application level isolation policy to an application level policy comprising isolation related requirements for configuration of a network function; and
sending the application level policy to the NFMF for configuring of one or more network functions.
