The disclosed subject matter describes herein methods, systems, and non-transitory computer readable media for configuring service networks. According to one aspect, the method includes collecting parameters defining a network service. In another aspect, the method includes generating a plurality of flow interfaces for modeling the network service based on the collected parameters, wherein each of the flow interfaces is associated with a logical device. In another aspect, the method includes generating at least one packet virtual network (PVN) including at least a portion of the plurality of generated flow interfaces. In another aspect, the method includes visually outputting, in a service network user interface, a graphical representation of the network service based on interface connectivities between the plurality of generated flow interfaces.
