Network and Performance Management

Network management is the process of administering and managing computer networks. Services provided by this discipline include fault analysis, performance management, provisioning of networks and maintaining the quality of service.

A small number of methods exist to support network and network device management. Network management allows IT professionals to monitor network components within large network area. Access methods include the SNMP, command-line interface (CLI), custom XML, CMIP, Windows Management Instrumentation (WMI), Transaction Language 1 (TL1), CORBA, NETCONF, and the Java Management Extensions (JMX).

Network performance management is the collective techniques that enable, manage and ensure optimal performance levels of a computer network. Network performance management generally requires the performance and quality service level of each network device and component to be routinely monitored.

Network performance management typically takes performance metrics from all across the network at a granular level. It reviews performance of the router to measure performance for each port

Network performance monitoring processes help in identifying performance bottlenecks, whereas network performance management ensures that problems are mitigated and the network is restored back to the required performance level. In addition to internal metrics, network performance management also reviews, analyzes, maintains and manages performance from a user perspective.

Key factors in network performance management include:

• Network delays
• Packet losses
• Throughput
• Packet transmission
• Error rate
