Problems solved by technology

[0003] For the HCA card, in the existing technical solutions, the official Mellanox driver is generally used, the driver is manually installed, and OFED’s built-in test tool is used to test the bandwidth of the HCA card on each model, and environment variables need to be configured for each test and other related complex work, and cannot realize automated testing
The test involves many test commands, the test commands are complicated, and it is easy to cause test errors. After the test, the results of each thread need to be checked one by one, and the total performance of the network cannot be obtained, and this test method is inefficient.

Embodiment Construction

[0043] The present invention provides a network bandwidth testing system based on HCA card configuration, such as figure 1 As shown, it includes: network node 1, network node 2 and test module; network node 1 is configured with HCA card 1, and network node 2 is configured with HCA card 2; network node 1 and network node 2 are connected through HCA card communication; the test modules are respectively Communication connection with network node 1 and network node 2; network node 1 is configured with at least three data blocks of different capacities;

[0044] The test module is used to send a data block to the network node 1 to send a control command, so that the network node 1 sends a data block to the network node 2 one by one according to the preset order, and records the sending time of each data block at the same time; the network node 2 is used for Receive the data blocks sent by network node 1 one by one, record the receiving time of each database, and feed back the recei...

Abstract

The invention provides a network bandwidth testing system based on HCA card configuration. A testing module sends a data block control command to a first network node, the first network node sends thedata blocks to a second network node one by one according to a preset sequence, and meanwhile sending time points of all the data blocks are recorded; the second network node receives the data blockssent by the first network node one by one, records receiving time of each database and feeds back receiving information and receiving time point information of all the data blocks to the first network node; the first network node sends the receiving information and receiving time point information, fed by the second network node, of all the data blocks and the capacity, number and sending time points of the data blocks to a testing module for storing. According to the system, testing personnel can further know the data unobstructed degree in a network. According to the system, the network bandwidth rate can be tested, and the unblocked degree of the network can also be tested.

Description

technical field [0001] The invention relates to the field of network testing, in particular to a network bandwidth testing system based on HCA card configuration. Background technique [0002] The network card performance test is to verify the performance data of the network card in the machine. By comparing the test results with the theoretical bandwidth of the network card, it can be judged whether the network card can exert its maximum performance on the machine. The industry often uses neteperf when testing network card performance. Netperf is a very common tool for measuring network bandwidth. It can set data blocks of different sizes to test whether the performance of network cards under different data blocks is consistent. [0003] For the HCA card, in the existing technical solutions, the official Mellanox driver is generally used, the driver is manually installed, and OFED’s built-in test tool is used to test the bandwidth of the HCA card on each model, and environm...
