There is provided systems and methods for Network Function Virtualization (NFV) in a control plane. The NFV framework is be used to define a plurality of virtual network functions (VNFs), each of which can correspond to a function enabling operation of a communication network. There is provided a method and system for managing a plurality of network slices in a communication network, the method comprising: instantiating a Global Control Plane set apart from the plurality of network slices, the Global Control Plane configured to at least partially manage each of the plurality of network slices.
