OSI upper layer protocol requirements for TMN operations

The authors addresses the operation systems (OS) and network element (NE) interface requirements for the service and protocols at the top three layers of the OSI model. Based on the needs of the operations, administration, maintenance, and provisioning (OAM&P) applications, which are the TMN (telecommunications management network) operations, subsets of the CCITT and ISO standards are defined. At the application layer of the OSI reference model, the different application service elements suitable for providing the maintenance and provisioning processes in today's telecommunications network are presented. Two categories of protocol suites are initially defined based on the requirements for OAM&P applications.>
