Embodiment Construction

[0060] The test method of first kind of AFDX switchboard transmission performance of the present invention, the steps are as follows:

[0061] Step 1. The sending end of the test device defines the network test frame, and calculates the bandwidth occupied by the VL used to send the network test frame; the frame length of the network test frame is not less than 64 bytes and not greater than 1518 bytes.

[0062] Step 2. According to the bandwidth described in step 1 and the maximum transmission rate of the AFDX switch, calculate the number of VLs required for full traffic transmission; the number of VLs required for full traffic transmission is equal to the maximum transmission rate of the AFDX switch divided by the steps 1 bandwidth.

[0063] Step 3. Construct full flow with empty data frames of the same frame length;

[0064] Step 4. The sending end of the test equipment sends the constructed full flow data to the receiving end of the test equipment through the AFDX switch;

Abstract

The invention provides a test method of the transmission performance of an AFDX switch. According to the test method, transmission virtual links (VL) are reasonably allocated, and port full-flow transmission can be realized, and function test requirements of the transmission ports of the AFDX switch under a limit (full-flow transmission) condition can be satisfied. With the test method adopted, transmission performance test can be performed on 24 ports of the AFDX switch fast and effectively, and therefore, the requirements of protocols can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and relates to a method for testing the transmission performance of an AFDX exchange. Background technique [0002] The AFDX network is a 100M full-duplex switched Ethernet. In order to ensure the normal communication of the network, the maximum transmission rate of its ports needs to reach 100Mbit / s. [0003] Generally, when the port of the AFDX switch sends data through VL (virtual link), the bandwidth occupied by the configured sending data is within 100M, and it is directly forwarded to the target machine through the AFDX switch. As long as the target machine receives the data, it means that the AFDX switch The send port is functioning normally. However, this method is not suitable for the function test of the sending port of the AFDX switch under extreme conditions (that is, full traffic sending). Contents of the invention [0004] Purpose of the present invention: the pres...
