Network Management


Network Management refers to the broad subject of managing computer networks. System administrators utilize a wide variety of software and hardware products to help their daily work. The network management model from ISO (International Standard Organization) covers five major functional areas of network management systems.

Performance Management

Performance management measures various aspects of network performance (such as network throughput, user response times, and line utilization) so that network performance can be maintained at an acceptable level. The process of performance management involves 1) gathering performance data, 2) analyzing data to determine normal levels, and 3) setting appropriate performance thresholds for important variables.

Configuration Management

Configuration management monitors and gathers network and system configuration information of hardware and software information. Information gathered are usually stored in a database for easy access and analysis.

Accounting Management

Accounting management concerns tracks the accountability of network utilization and resource allocation. The process of accounting management includes 1) measuring utilization of all important network resources, 2) analyzing current usage patterns, 3) and setting usage quotas for various user groups. The goal of accounting management is to maximize network resource utilization.

Fault Management

Fault management is the most widely implemented of the ISO network management elements because faults can cause downtime and negatively impact the network operation. Fault management detects, logs, notifies, and automatically fix some of network problems to keep the network running effectively. The process of fault management involves 1) determining symptoms and isolating the problem, 2) fixing the problem and testing the solution, and 3) recording the detection and resolution of the problem..

Security Management

The goal of security management is to control access to network resources according to user privileges to safeguard sensitive information. The process of security management involves 1) identifying sensitive network resources, 2) determining mappings between sensitive network resources and user groups, 3) monitoring user access to sensitive network resources.
