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 compared to Internet network management framework Manajemen Jaringan, Sukiswo ST, MT

4 Basic Management Model MANAGING SYSTEM MANAGED SYSTEM Transfer of management information and notifications Manager Agent Managed objects Manajemen Jaringan, Sukiswo ST, MT

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 Manajemen Jaringan, Sukiswo ST, MT

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 Manajemen Jaringan, Sukiswo ST, MT

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 Manajemen Jaringan, Sukiswo ST, MT

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 Manajemen Jaringan, Sukiswo ST, MT

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 Manajemen Jaringan, Sukiswo ST, MT

17 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

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 Manajemen Jaringan, Sukiswo ST, MT

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 Manajemen Jaringan, Sukiswo ST, MT
