Problems solved by technology

Since the active measurement is to inject test packets into the network to test the network characteristics, a reference node needs to be set in the network during the test, and the network performance test tool is used to test the IP network performance of the network link between a node in the network and the reference endpoint. Therefore, its advantages are relatively high controllability of the measurement process, flexibility, flexibility, and ease of end-to-end IP network performance measurement; but its disadvantages are also very obvious: the injected measurement traffic will change the operation of the network itself, making the measurement The results deviate from the actual situation, and measuring traffic will increase the network burden

Embodiment Construction

[0015] Concrete method of the present invention is as follows:

[0016] 1) Using initial test parameters, initiate active measurements and collect their measurement results;

[0017] 2) Increase or decrease the test parameters, initiate the second active measurement, and collect the measurement results;

[0018] 3) Adjust the test parameters according to the two active measurement results, initiate the active measurement again, and collect the measurement results;

[0019] 4) Repeat step 3) until the user stops the measurement.

[0020] In step 3), if the IP packet transmission delay (or IP packet loss rate, response time, jitter, etc.) The bandwidth used for the measurement. If the IP packet transmission delay (or IP packet loss rate, response time, jitter, etc.) remains unchanged or decreases, continue to increase the test parameters to increase the bandwidth occupied during active measurement.

[0021] The proportion of increasing or decreasing the test parameters can b...

Abstract

The invention relates to a method for collecting the IP network property actively, which comprises: (1) using initial test parameter, to initialize the active measurement and collect the result; (2) increasing or decreasing the test parameter, to initialize the second active measurement and collect the result; (3) based on said two results, adjusting the test parameter to initialize the active measurement again and collect the result; (4) repeating the step (3) until the user stops measuring. The invention cans solve the problem of background technique, which can change the test parameter, based on the result of active measurement, to obtain the useful bandwidth of network.

Description

1. Technical field [0001] The invention relates to the technical field of IP network communication, in particular to a method for collecting IP network performance through active measurement. 2. Background technology [0002] At present, the Internet carries more and more important applications, and the network structure is becoming more and more complex. The measurement of IP network performance is an important means to deeply understand the behavior characteristics of the entire network, analyze and discover network performance bottlenecks, optimize network resource allocation, strengthen network management, and improve network performance. [0003] At present, there are mainly two ways to measure IP network performance: active measurement and passive measurement. [0004] Active measurement is done through network performance testing tools. The results of active measurement generally include: throughput, response time, jitter, IP packet transmission delay, IP packet loss...
