Problems solved by technology
[0003] However, in actual network operation, sudden traffic influx often occurs, and the duration of this sudden traffic influx is also uncertain. It may last for a long time, or there may be only 2 -3 minutes or even less
[0004] Through the 15-minute performance monitoring technology, it is possible to monitor the burst traffic that lasts for a long time, but for the burst traffic that only exists within 2-3 minutes, it will be counted on average to the total duration of 15 minutes, so that the burst traffic Covered in the 15-minute total statistical traffic, it cannot truly reflect the status of traffic changes

Embodiment Construction
[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0046] In network performance monitoring, the present invention is proposed aiming at the capture of sudden influx traffic, especially short duration burst influx traffic.
[0047] figure 2 It is a flowchart of an embodiment of the network performance monitoring method of the present invention.
[0048] Such as figure 2 Shown, the method of this embodiment comprises:
[0049] S210, setting a real-time monitoring period. Usually, the duration of the real-time monitoring period is shorter or much shorter than the monitoring statistics period. For example, if the monitoring statistics period is 15 minutes, then the real-time monitoring period can be set to 1 second.
[0050] During specific implementation, the real-time monitoring cycle can be set according to the accuracy...

The invention discloses a network performance monitoring method and device, and relates to the field of network monitoring. The monitoring method includes: counting the received data flow according to the set real-time monitoring cycle; determining the real-time change of the data flow in each real-time monitoring cycle; Adjust the accuracy of network performance monitoring according to the real-time changes of data traffic in each real-time monitoring cycle and its duration. Therefore, according to the real-time changes in data traffic, the accuracy of network performance monitoring is adaptively adjusted, and sudden influx of traffic is captured.
Description
technical field [0001] The invention relates to the field of network monitoring, in particular to a network performance monitoring method and device. Background technique [0002] A passive optical network (Passive Optical Network, PON) has been widely deployed at present. Since terminals are online at different times and services used are also different, the service traffic on the uplink Ethernet port of an optical line terminal (Optical Line Terminal, OLT) generally presents certain fluctuations. At present, the commonly used performance monitoring technical means is to perform periodic data statistics of 15 minutes and 24 hours on the monitored Ethernet port according to the technical specifications of the IETF. [0003] However, in actual network operation, sudden traffic influx often occurs, and the duration of this sudden traffic influx is also uncertain. It may last for a long time, or there may be only 2 -3 minutes, or even less. [0004] Through the 15-minute per...
