1. Introduction Open Management
Automated Network and Systems Management in a Non-Proprietary, Widely Accepted Standard Fashion.
OSI Management (ISO/ITU-T). Internet Management. Not Limited to CMIP and SNMP.

Why Open Management Interoperability
Ability of individual components within an open management environment to exchange information (i.e., interworking) Portability
Ability to easily place management functions in various platforms. Integration
Integration of lower-level, individual (e.g. element management) systems to achieve higher-level, integrated management (e.g., service management).

2.3 X/Open XMP/XOM X/Open = Portability XMP
Provide CMIS and SNMP Service API. Recognizes Both GDMO and SNMP MOs.
XOM Maps ASN.1 data to a uniform data structure "om_object". Provide API for the manipulation of om_objects. Base for XMP Interface.

Use IRB to Support XMP (CMIP and SNMP). Object Management Framework
Extend CORBA to provide MRB. (I4DL)Use DCE's RPC for Broker Communications.

3. Issues in Open Management Standardization is always in progress. Options in standards will be an
interoperability barrier. Interoperability Testing. Interworking among standards. XMP/XOM API Complexity. Coexistence with Legacy systems. ...

4. Conclusion Open management is a big trend. From element management to
service management. OSI management systems emerge. TMN: a focal point Follow, Join, or Lead?
