Problems solved by technology

The advantage of passive measurement is that it only observes network node devices, so theoretically it does not generate redundant traffic and does not increase the network burden; its disadvantage is that passive measurement can only count the traffic on a certain network device
It is difficult to measure the end-to-end performance of the network, and it is also impossible to measure the maximum load of the network

Embodiment Construction

[0023] see figure 1 , the concrete process of the method of the present invention is as follows:

[0024] 1) Start the timer according to the preset sampling time interval, and collect the IP network performance of the network equipment on the egress node of the user network once through a passive measurement method;

[0025] 2) Collect the measurement results of the exit nodes of the user network obtained through passive measurement, and calculate the throughput;

[0026] 3) According to the throughput obtained in step 2), set the test parameters of active measurement, the test parameters include reference node, user network exit node, sending rate, test packet size and the protocol type used during the test, etc., mainly by adjusting The sending rate is used to reduce the burden on the network during active measurement. The calculation formula for adjusting the sending rate S is:

[0027] S=(U-T)×M(0

[0028] Among them, U is the bottleneck bandwidth, T is the actual...

Abstract

The invention relates to a method for collecting IP network property via active and passive measurements, wherein it comprises: 1, based on preset sampling time space, start the timer, via the passive measure method, to collect the IP network property of network device at the one-time user network port node; 2, collecting the measured result and calculating out the throughout; 3, based on the throughout, setting the test parameter of active measurement; 4, starting the active and passive measurements; 5, collecting the IP network property of end-to-end network chain circuit obtained by active measurement; collecting the measured result of user network port node obtained by passive measurement; 7, storing all measured results. The invention can solve the problem that added network load when in active measurement of background technique, and solve the defects of passive measurement, to obtain the end-to-end network property and the maximum load.

Description

1. Technical field [0001] The invention relates to the technical field of IP network communication, in particular to a method for jointly collecting IP network performance through active measurement and passive 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 a test done through network performance testing tools. The results of active measurement generally include: throughput, response time, jitter, IP pa...
