1. A method for propagating placement constraints and isolation requirements, from user intents and operator policies to constituents of user requested network slices (NwSs) and communication services (CSs), comprising:
decomposing the user intents and the operator policies into functionalities corresponding to the constituents of the requested NwSs and CSs, and storing the functionalities in a solution map (SM) model;
propagating the placement constraints to the functionalities in the SM model;
propagating the isolation requirements to the functionalities in the SM model; and
deploying constituent virtual network functions (VNFs) and physical network functions (PNFs) of the NwSs and CSs, according to the corresponding functionalities of the SM model.
