IP Flow Performance Measurement (FPM) end-to-end performance statistics collection measures packet loss and delay on the entire network so that carriers can quickly respond to resolve network issues if network performance deteriorates.
The NetEngine 8000 F supports proactive and on-demand IP FPM end-to-end performance statistics. These functions apply to different scenarios:
Proactive performance statistics apply when you want to monitor network performance in real-time. After you configure this function, the system continuously implements performance statistics on packet loss or delay.
On-demand performance statistics apply when you want to diagnose network faults or monitor network performance over a specified period. After you configure this function, the system periodically implements performance statistics on packet loss or delay.
These measurements serve as a reliable reference for network operation and maintenance and fault diagnosis, improving network reliability and user experience.
Before configuring IP FPM end-to-end performance statistics collection, complete the following tasks:
Configure a dynamic routing protocol or static routes so that devices are reachable at the network layer.
Configure the network time protocol (NTP) or 1588v2 so that all device clocks can be synchronized.
