A computer-implemented method for identifying virtual local area networks VLANs (110n, 112n, 114n) associated with a network, the method comprising: gathering actual network element configuration data from a plurality of network elements in the network by periodically polling the plurality of network elements after at least one initial VLAN provisioning, wherein the actual network element configuration data identifies one or more VLANs (110n, 112n, 114n) that at least some of the plurality of network elements are actually allocated to; correlating the actual network element configuration data with administrative VLAN data, wherein the administrative VLAN data identifies one or more VLANs recognized by a business process, the administrative VLAN data comprising a plurality of data objects in a VLAN provisioning data store, a plurality of data objects in a VLAN configuration generation data store, and a plurality of data objects in a VLAN orders data store; wherein the act of correlating comprises mapping corresponding data fields in the plurality of data objects from at least two of the VLAN provisioning data store, the VLAN configuration generation data store, and the VLAN orders data store against one another; and wherein the correlating determines one or more VLANs (110n, 112n, 114n) that are not commonly identified in both the actual network element configuration data and the administrative VLAN data; and receiving a reservation request to reserve a specified VLAN (110n, 112n, 114n) and storing in the VLAN provisioning data store in association with a VLAN ID of the specified VLAN a reserved indicator, an entity identifier and network element identifiers, wherein: a said data object of the VLAN provisioning data store includes a VLAN identifier for a VLAN that a business process indicates is or should be provisioned, a logical site identifier and a service component identifier identifying a network-based service or product; a said data object of the VLAN configuration generation data store includes a said service component identifier and is configured to accept different attribute inputs including IP addresses and VLAN identifiers and to generate configurations that designate particular device criteria comprising vendor, brand or model, wherein a said configuration is applicable to network elements comprising routers and devices; and a said data object of the VLAN orders data store includes a said service component identifier, a product instance identifier identifying a state of a service or product identified by the service component identifier, a part number identifying a product related to an order, and a business organization identifier and a business organization name that specify which business organization the order is associated with. gathering actual network element configuration data from a plurality of network elements in the network by periodically polling the plurality of network elements after at least one initial VLAN provisioning, wherein the actual network element configuration data identifies one or more VLANs (110n, 112n, 114n) that at least some of the plurality of network elements are actually allocated to;
