3. 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

4. Basic Management Model MANAGING SYSTEM MANAGED SYSTEM Transfer of management information and notifications Manager Agent Managed objects

5. 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. 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. 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

13. OSI Management Functional Areas • Configuration Management • Fault Management • Performance Management • Security Management • Accounting Management

15. 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. 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. Systems Mgmt Functions (3) • Security-Audit Trail • specifies the kinds of event reportsthat 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. 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
