Although the different management frameworks provide mechanisms of inter-manager-communication (OSI/TMN: x reference point, SNMP: inform-pdu), it is currently not clear what the shared management knowledge between MSs should look like and what actions may be initiated by an MS on behalf of another one. We will now first describe what kind of management information ought to be present in an object model for managing MSs and will then move on to the required management services, i.e., the functionality that MSs may provide for interacting with peers. The identification of management information and management functionality was based on a use case analysis [7] applied to typical management scenarios. For the sake of brevity, we can only describe a small part of the amount of management instrumentation identified in our analysis. The complete set is described in [11].
