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
