[edit] Overview
The ISO under the direction of the OSI group has created a network management model as the primary means for understanding the major functions of network management systems.
The model in question is interchangeably called either the OSI network management model or ISO network management model so the full name could be the OSI/ISO network management model.
[edit] The 4 parts of the model
[edit] Organization
This describes the components of network management such as a manager, agent (MA), and so on, and their relationships
[edit] Information
This describes the structure and storage of network management information. The information is stored in a database, called a management information base (MIB). Also defined was the Structure of Management Information (SMI) to define the syntax and semantics of management information stored in the MIB.
[edit] Communication
This deals with how the management data is communicated between the agent and manager process. It is concerned with the transport protocol, the application protocol, and commands and responses between peers.
[edit] Functional
This addresses the network management applications that reside upon the Network management station (NMS).
[edit] The 5 areas of function of the model
The OSI network management model categorizes five areas of function, sometimes referred to as the FCAPS model:
[edit] Fault
The goal of fault management is to recognize, isolate, correct and log faults that occur in the network.
[edit] Configuration
The goals of configuration management are to gather/set/track configurations of the devices.
[edit] Accounting
The goal is to gather usage statistics for users
[edit] Performance
The goal is to both prepare the network for the future, as well as to determine the efficiency of the current network.
[edit] Security
The goal of security management is to control access to assets in the network.
[edit] Standards
The two standards that have emerged are :
- Simple Network Management Protocol SNMP by IETF
- Common management information protocol CMIP by ITU-T
