Distributed intelligent monitoring and reporting facilities are of paramount importance in both service and network management as they provide the capability to monitor quality of service and utilisation parameters and notify degradation so that corrective action can be taken. By intelligent, we refer to the capability of performing the monitoring tasks in a way that has the smallest possible impact on the managed network, facilitates the observation and summarisation of information according to a number of criteria and in its most advanced form, permits the specification of these criteria dynamically to suit the particular policy in hand. In addition, intelligent monitoring facilities should minimise the design and implementation effort involved in such activities. The ISO/ITU Metric, Summarisation and Performance management functions provide models that only partially satisfy the above requirements. This paper describes our extensions to the proposed models to support further capabilities, with the intention to eventually lead to fully dynamically defined monitoring policies. The concept of distributing intelligence is also discussed, including the consideration of security issues and the applicability of the model in ODP-based distributed processing environments.

“…Such interfaces help a lot the TMN application developer by providing the opportunity to spend more time on the application functionality rather than being concerned with handling the complexity of the "raw" CMIS service. Work on high-level, object-oriented Q (CMIS and Directory Access) APIs in C++ has been conducted in the RACE Integrated Communications Management (ICM) project [3], resulting in OSIMIS object-oriented TMN platform [1] [3]. Work is also ongoing in this area for the standardization of such APIs, driven by the Network Management Forum (NMF) [4].…”

“…The OSIMIS high-level C++ APIs encapsulate the underlying CMIS and Directory Access services and the Q protocol stack by using object-oriented principles and techniques. One particular abstraction for TMN OSFs functioning in managing role is the Remote MIB (RMIB) [3][1] access infrastructure, which involves the use of proxy objects (of a RMIBAgent class). These act as the local image of the remote agent applications (one-to-one mapping), and provide CMIS-like message passing, simplifying many of the CMIS access details e.g.…”

“…While this approach is protocol-oriented, higher-level abstract approaches are possible. A Shadow MIB (SMIB) approach is described in [3] and an interpreted Tcl layer may be put in front of it in a similar fashion to Tcl-RMIB. Alternatively, similar infrastructure may be built directly over the Tcl-RMIB using one of the object-oriented Tcl extensions.…”

The OSIMIS (OSI Management Information Service) platform provides the foundation for the quick, efficient and easy construction of complex management systems. It is an object-oriented development environment in C++ [Strou] based on the OSI Management Model [X701] that hides the underlying protocol complexity (CMIS/P) and harnesses the power and expressiveness of the associated information model [X722] through simple to use Application Program Interfaces (APIs). OSIMIS combines the thoroughness of the OSI models and protocols with advanced distributed systems concepts pioneered by ODP to provide a highly dynamic distributed information store. It also combines seamlessly the OSI management power with the large installed base of Internet SNMP [SNMP] capable network elements. OSIMIS supports particularly well a hierarchical management organisation through hybrid manager-agent applications and may embrace a number of diverse technologies through proxy systems. This paper explains the OSIMIS components, architecture, philosophy and direction.
