An operation support system architecture has been developed for network element allocation in optical access networks (OANs). Rather than deploying OAN elements to meet all potential customer demand, which would be very costly, only enough elements to meet current demand are installed. These elements are then allocated during service provisioning. The sequence of element allocation and re-allocation is controlled because OANs consist of various types of elements, including outside fibers, inside fibers, and equipment. Functions are provided for allocating each type of element; also provided is an allocation integration function to control the element allocation processes. Moreover, an efficient process for allocating the elements has been determined: first, the outside fiber is allocated, then the equipment, and finally the inside fiber.
