Problems solved by technology

[0004] 1) RFC2544 test standard, testing network bandwidth, delay, and packet loss rate only supports offline testing, and is helpless for online business testing
[0005] 2) RFC2544 test standard, test network bandwidth, delay, packet loss rate test results, can only display end-to-end bandwidth, delay, packet loss rate, can not make statistics on the bandwidth, delay, packet loss rate of intermediate devices, Therefore, the location of the network failure point cannot be found
[0006] 3) RFC2544 test standard, test bandwidth, delay and packet loss rate, need to be carried out in three steps, the test efficiency is low
[0007] 4) The network loopback scheme can only loop back all data on the port, and cannot selectively loop back data packets of some data streams

Embodiment 1

[0043] Ethernet was originally designed for LAN. Since LAN itself has high reliability and stability, no management and maintenance mechanism was established at the beginning of Ethernet design. Compared with LAN, MAN and WAN are rapidly expanding in terms of link length and network scale, so the lack of an effective management and maintenance mechanism has become a serious obstacle to the application of Ethernet technology in MAN and WAN.

[0044] combine figure 2 , the present embodiment provides a network intelligence testing method, comprising the steps of:

[0045] Step 1) Set the main control instrument at the user end of the test network, set the loopback pass-through instrument in the test network, connect the main control instrument with the loopback passthrough instrument to form a loopback path, and the main control instrument sends control frames to said loopback passthrough meter;

[0046] The loop-through meter in the present invention can be connected in seri...

Embodiment 2

[0079] On the basis of Embodiment 1, the present invention also provides another embodiment of the method for network intelligence testing, specifically as follows:

[0080] S101: The operation and maintenance personnel hang a meter on the user end and the central office respectively. After configuring the corresponding IP address, the main control instrument at the user end sends a route tracking operation to the loopback instrument at the central office, finds the IP address of the network device passing between the main control instrument and the loopback instrument, and generates a network topology map. figure 2 It is a network topology diagram. As can be seen from the figure, the loopback passthrough instrument can be located at any position in the test network, which is one of the distinguishing technical features from the prior art. The loopback passthrough instrument in the present invention can be connected in series on the Internet At any position in the network, th...

Embodiment 3

[0102] combine Figure 4 , this embodiment is an application embodiment, illustrating the test network environment as an example:

[0103] Such as Figure 4 Shown:

[0104] The operator opens a 1G dedicated line service for user A, user B, user 1, user 2, user 3, and user 4 respectively, and the bandwidth is 200M, 400M, 400M, 400M, 400M, and now user A and user B give feedback The bandwidth is not enough for 200M. At this time, the operation and maintenance personnel need to test and locate the network bandwidth and the location of the fault point that causes insufficient network bandwidth. Suppose the bandwidth of user A and user B is only 160M. The location of the faulty device point is "intermediate device 2".

[0105] The current operation and maintenance personnel testing method is as follows:

[0106] User A and user B each have a meter, A meter is tested according to the RFC2544 standard, and B meter performs a loopback to test the bandwidth between user A and use...

Abstract

The invention discloses an intelligent network testing method. The intelligent network testing method comprises the following steps: (1) sending a control frame to a loopback punch-through instrument by a main control instrument; (2) receiving and detecting the control frame by the loopback punch-through instrument, responding the control frame and establishing connection configuration; (3) configuring testing parameters according to the control frame by the main control instrument; (4) tracking a chain by the main control instrument to obtain a network topology to obtain all network equipment information between the main control instrument and the loopback punch-through instrument; (5) remotely logging in a web master by the main control instrument and counting initial data; (6) carrying out a network test by the main control instrument, and receiving and transmitting a data package and counting; carrying out a loopback testing frame on the data package, which is received by the loopback punch-through instrument, of the main control instrument, and punching through other user frames which do not need to be subjected to the loopback test; (7) obtaining testing receiving and transmitting data packages of network equipment by the main control instrument and comparing the data packages transmitted in the step (6) to obtain bandwidth, time delay and fault position points; and (8) generating a testing report by the main control instrument.

Description

technical field [0001] The invention belongs to the field of communication test, including the test and maintenance of Ethernet network, the test and maintenance of community broadband, customer dedicated line and group network, and relates to a network intelligent test method. Background technique [0002] In the stage of broadband service opening and operation and maintenance, users are most concerned about whether the network speed of the dedicated line used meets the demand, and operation and maintenance personnel are most concerned about finding the location of the fault point that affects the network bandwidth when the user bandwidth cannot meet the requirements; when the operation and maintenance personnel use the instrument to test the network , the most concerned thing is to be able to quickly locate the location of the fault point. The traditional test method is that the operation and maintenance personnel hang a meter on the user end and the central office respect...
