An operation support system architecture for network provisioning of optical access networks

We describe an operation support system (OSS) architecture for network element (NE) allocation in optical access networks (OANs). Deploying OAN elements to meet all customer demand would be very costly because access networks are extend in many directions. To reduce this cost, it would be necessary to only install enough NEs to meet the current demand, and to allocate suitable elements during the process of service delivery. Because OANs consist of several elements, it is also necessary to control the sequence of element allocation and re-allocation. Therefore, an allocation integration function to control the allocation processes is necessary, as well as functions for each NE allocation. We have developed an OSS architecture that meets these requirements. We have also determined the most efficient allocation process for allocating OAN elements.
