The management of telecommunication systems based on TDM (Time Division Multiplexing), IP (Internet Protocol), or optical protocols, or a mixture of those technologies, is typically structured hierarchically. Above the Element Management and the Domain Management Layer, the Service Management Layer is situated. On top of the hierarchy is the Business Management Layer. Generally speaking, the different management layers are separated components, which can be located on different physical machines and may be based on different technologies. This requires interfaces between the different layers. Whereas the interfaces between the Element Management and the Domain Management Layer are usually technology-specific, the interfaces between the Domain Management and the Service Management Layer and especially between the Service Management and the Business Management Layer are usually customized with respect to business process aspects. Considering the common case that the lower three layers of the management pyramid are provided by the vendor of the network elements (NEs), it would be advantageous to have standardized, flexible, and easy-to-handle interfaces in the Service Management Layer, which can be used and implemented by some external OSS (Operations Support System) or BSS (Business Support System).
