To place the anecdotal scenarios in the structured framework, the International Organization for Standardization (ISO) has created a network management model.
Areas of Network Management:
These are areas of network management as defined below:
- Performance Management:
To quantify, measure, report, analyze, and control the performance (e.g, utilization and throughput) of different network components are the main goal of performance management. These components include individual devices (e.g, links, routers, and hosts) as well as the end to end abstraction such as a path through the network. Protocol standard such as the Simple Network Management Protocol (SNMP) play a central role in Internet performance management.
- Fault Management:
The goal of fault management is to log, detect, and respond to fault condition int the network. The difference between fault management and performance management is blurred.
The fault management is used to manage immediate handling of the failures like link failure, host failure, or router hardware problem, these problems are also known as a transient network failure. With the help of performance management, the SNMP protocol plays a major part in fault management.
- Configuration Management:
Tracking of the devices that are on the managed network and the hardware and software configurations are allowed by Configuration management.
- Accounting Management:
To specify, log, and control user and device access to network resources are allowed by Accounting management. usage quotas, usage-based charging, and the allocation of resource-access privileges all fall under accounting management.
- Security Management:
The goal of security management is to control access to network resource according to some well-defined policy. The key distribution centres are a component of network management.
The use of firewalls to monitor and control external access point to one’s network is another crucial component.
