The Telecommunications Management Network (TMN) has been recommended by the International Telecommunication Union (ITU) and is a distributed environment. It consists of a large number of processes that are responsible for collecting and processing many kinds of information regarding the resources and services of the managed network, and cooperate in order to manage the underlying telecommunications network. Due to the large number of management processes, we consider their management essential. This thesis faces the above problem and deals with the efficient configuration management of the TMN. For this purpose, in the first part of the thesis, we propose a management architecture using standards being recommended from ISO. We enhanced the OSI agent/manager model with mechanisms for the automatic update and retrieval of information and the automatic transfer of configuration software packages. We introduce the role of a Metamanagement Agent (MMA) which manages objects representing management processes running on the TMN. Addittionally, we introduce the role of a Metamanagement Operations System (MMOS) which emits management operations to the MMAs. Then, we use mechanisms that ensure that faults in the TMN are properly detected and appropriate actions are taken, which, most of the times lead us to the reconfiguration of the system. Towards the development of a complete and efficient management system we decided to use the capabilities offered by the distributed environments. In order to achieve this, in the second part of this thesis we propose a resource configuration management system based on standards being recommended from TINA-C. We use a managed system which consists of managed objects representing management processes running on the TMN. We also use a managing system consisting of managing objects which perform operations on the managed objects. We enhance the above model with mechanisms for the automatic reposit, update and retrieve of information and with the ability of emitting notifications. Addittionally, we deal with the detection of failures and the reconfiguration of the system. At the last part of the thesis we compare the two models introduced above and we develop the reasons that lead us to the resource configuration management system.
