1. A method of mapping a service-level topology for a service to a service-specific data plane logical topology for a network having a plurality of physical network nodes, comprising: receiving service parameters for the service; locating logical network nodes for the service-specific data plane logical topology at respective physical network nodes among the plurality of physical network nodes according to the service parameters, the service-level topology, and a physical infrastructure of the plurality of physical network nodes, wherein the logical network nodes comprise respective software defined entities; defining connections among the logical network nodes according to the service parameters, the service-level topology, and the physical infrastructure; defining respective connections for a plurality of user equipments (UEs) to at least one of the logical network nodes according to the service parameters, the service-level topology, and the physical infrastructure; and defining respective functionalities for the logical network nodes.
