This paper presents a methodology for thespecification and design of multi-domain managementsystems that control, monitor and administer users andservices in a distributed telecommunication environment. It presents a framework, which serves as ablueprint for the design and implementation ofdistributed management applications. It defines a set ofconcepts and methods for guiding the analysis, design, and implementation phases of managementapplications, which are distributed over heterogeneoussystems. The framework is based on concepts ofTelecommunications Management Networks and OpenDistributed Processing, and is partially developed withinthe Pan-European Reference Configuration for IBC(Integrated Broadband Communication) Services Management(PRISM) project.

The Remote network-MONitoring (RMON) standard isa valuable addition to the Simple Network ManagementProtocol (SNMP), providing network managers withimportant global network information. Unlike SNMPagents, RMON agents operate in promiscuous mode andprocess all packets traversing the local net. The RMONmanagement information base (MIB) supplements the SNMPMIB-II standard MIB. We present common network problems that cannot be solved using existing MIB-II orRMON objects. To solve these problems, we developextensions to the RMON matrix group to gather networklayer statistics that result in a view of packet traffic beyond the local network. Our extensionsincrease the ability to analyze and solve networkconfiguration problems and perform troubleshooting. Wedemonstrate our results by implementing and analyzingtwo “live” internetworking problems. Datacollected from these experiments showed that networktraffic patterns can be isolated by individual subnets,thus more easily identifying sources ofcongestion.

This paper describes the essential specificationand design of a CMIP-SNMPv2 application gateway fornetwork management integration and interoperability.Such a intermediate proxy software device allows management of Internet MIB-II objects throughISO/CCITT manager supporting CMIP protocol and CMISmanagement services. All the gateway functionality areexplained using dataflow diagrams. CMIP indication PDUs are transformed into functionallycorresponding SNMPv2 PDUs. Detailed service-mapping andname-mapping aspects consistent with the protocols,Internet MIB-II and the GDMO MIB are fully explored.SNMPv2 to CMIP inverse mapping is also explained indetail, followed by conclusions capturing the salientaspects of this design.

In Telecommunications Management Network (TMN),the interworking of manager and agent requires thesharing of management information defined as SharedManagement Knowledge (SMK) in ITU-T Recommendation M.3010. SMK includes information on theprotocol knowledge, management functions, managed objectclasses and their instances, and authorizationcapabilities. We have developed a CORBA-based TMN SMKsystem in order to provide a dynamic and efficientdistributed processing environment for the exchange ofmanagement information between managers and agents. Inthis paper, we discuss the design issues and present the design of a CORBA-based SMK systemincluding the access protocol for obtaining the SMKinformation from MIB and for SMK context negotiations.Also, our effort on the prototype implementation of anSMK system using ORBeline and OSIMIS is presented.The preliminary performance results of our prototypeimplementation show that ORB-based SMK informationaccess outperforms CMIS-based SMK information access, and that our approach is an efficient way ofexchanging SMK information.

OSI systems management is a set of standards forthe management of open systems. Its acceptance by theindustry has been slower than that of SNMP, due to itsrelative complexity. However, it is gathering more and more momentum due to the increasingavailability of development tool kits and also due tothe real world implementations which have followed theuse in TMN. This paper contrasts OSI systems management to SNMP and TMN. It identifies the salientcharacteristics of OSI systems management and uses themas bases for the comparison. Aspects of X.25 managementare used for illustration purpose. OSI system management is half way between SNMP and TNM. It offersmore than SNMP, but less than TMN. SNMP, OSI systemsmanagement and TMN tackle different classes ofmanagement problems. None is a panacea andinteroperability is the key issue.
