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 & many areas are still being refined
and standardized

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
6
Keimyung University
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
7
Keimyung University
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
16
Keimyung University
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
17
Keimyung University
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
18
Keimyung University
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
19

OSI Management Standards• OSI Management Standards are divided into five
categories:– OSI Management Framework and Overview– Management Information Model– CMIS/CMIP– Systems-Management Functions– Layer Management
