Test method and system of network management node calculation

Abstract

The invention discloses a test method of network management node calculation. The method comprises that a first statistical value of a network management node is read at first time, a second statistical value of the network management node is read at second time, the first and second time are two time of constant flow rate, a time difference between the first and second time is an integer times of a data update period of the network node, and the first and second statistical values are network management statistical values; a capturing packet tool is used to calculate a practical value corresponding to the network management node in a period from third time to fourth time, the third and fourth time are two time of constant flow rate, and a time difference between the fourth and third time equals that between the second and first time; and the practical value corresponding to the network management node is compared with the difference between the first and second statistical values. The invention also discloses a system for realizing the method.

Description

technical field [0001] The invention relates to the technical field of network management testing, in particular to a test method and system for network management node statistics. Background technique [0002] In the prior art, the network administrator monitors the network equipment through the network management system, and the monitored equipment regularly reports the status data of itself or the network to the network management system, and the network management system monitors the equipment and the network by collecting and reporting the status data. These status data are composed of various parameters that reflect the operating conditions of equipment or networks, and each parameter here is called a network management node. [0003] Whether the parameters recorded by the network management node of the device are consistent with the actual situation needs to be verified by testing. Some of the network management nodes that count data traffic, such as the number of by...

AI Technical Summary

Problems solved by technology

Some of the network management nodes that count data traffic, such as the number of bytes received by the device port, cannot be accurately measured using traditional methods, because:

[0004] 1) In addition to the data message of the device under test, there are also management control protocol messages in the network. The sending time and quantity of the data message of the device under test are controllable, and the sending time of the management control protocol message and the number is uncontrollable, but the current actual test does not count all the management control protocol packets received by the device under test, and the test error is relatively large;

[0005] 2) The statistics of the network and equipment parameters by the network management node are not real-time, but are counted according to the set period intervals, and the parameters to be tested are reported, and the data update of the network management node is not synchronized with the statistical test operation, resulting in large test errors
