Why Open Management

Interoperability


Portability


Ability of individual components within an open
management environment to exchange information
(i.e., interworking)
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).

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.

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.
