Introduction
 OSI Systems Management is a collection of standards for




network management that includes:
– management service and protocol
– definition of management information
– systems management functions
Joint standards by ISO & ITU-T (formerly CCITT)
Widely known as “CMIP”
used mostly in Telecommunications Network
Management
Very complex compared to Internet network management

Basic OSI Terminology (1)
 Managed Object (MO): an abstract representation of a
resource to be managed
 Attribute: a property of an MO (~ instance variable in SNMP)
 Management Information Base (MIB): the
conceptual repository of management information consisting of a set of
MOs, together with their attributes
 Systems management functions: functions in the
application layer related to the management of various OSI resources
and their status across all layers of the OSI architecture
 Systems management application process
(SMAP): an application process participating in systems
management

5
Basic OSI Terminology (2)
 Systems management application entity (SMAE): an





application entity which performs systems-management
communication
Layer management: the management of each OSI layer
Layer management entity (LME): an entity that performs
management-related activities for the specific OSI layer
Systems management service: a named set of primitives
that provide a service for use in systems management
Systems management protocol: an application-layer
protocol supporting systems-management services
Systems management application-service element
(SMASE): an application-service element providing
systems-management services

Basic OSI Terminology (3)
 Common management information service element




(CMISE): an application-service element used to exchange
information and commands for the purpose of systems
management
Common management information services (CMIS): the
set of services provided by the CMISE
Common management information protocol (CMIP): an
application-layer protocol supporting CMIS
Association control service element (ACSE): an
application-service element (ASE) supporting associations
with other entities
Remote operation service element (ROSE): an ASE
supporting remote operations with remote entities

Systems Mgmt Functions (1)
 Object Management
– supports the creation and deletion of MOs and the
reading and changing of object attributes
 State Management
– specifies a model for how the management state of an
object is to be represented
 Relationship Management
– specifies a model for representing and managing
relationships between MOs.
 Alarm Reporting
– supports the definition of fault alarms and the
notifications used to report them
Manajemen Jaringan, Sukiswo ST, MT
15
Systems Mgmt Functions (2)
 Event-Report Management
– supports the control of event reporting,
including the specification of recipients of reports,
the definition of reports, criteria for generating
and distributing reports
 Log Control
– supports the creation of logs, the creation and
storage of log records, and the criteria for
logging
 Security-Alarm Reporting
– supports the definition of security alarms and
the notifications used to report them
Manajemen Jaringan, Sukiswo ST, MT
16
Systems Mgmt Functions (3)
 Security-Audit Trail
– specifies the kinds of event reports that
should be contained in a log used for security
evaluation
 Access Control
– supports the control of access to management
information and operations
 Accounting Meter
– provides for accounting for the usage of system
resources and a mechanism for enforcing
accounting limits
Manajemen Jaringan, Sukiswo ST, MT
17
Systems Mgmt Functions (4)
 Workload Monitoring
– supports the monitoring of attributes of MOs
that relate to the performance of a resource
 Test Management
– supports the management of confidence and
diagnostic test procedures
 Summarization
– supports the definition of statistical measures
to be applied to attributes and the reporting of
summarized information
