Embodiment 1

[0064] see figure 2 The method for sending a test message provided by Embodiment 1 of the present invention includes the following steps:

[0065] S101. Construct an Ethernet message in advance;

[0066] In Embodiment 1 of the present invention, the Ethernet message has a message feature value that is different from other Ethernet messages. Although the message feature value is not unique, the probability of repetition is extremely small. Therefore, according to the message feature value It is sufficient to distinguish this Ethernet message from other Ethernet messages. The message feature value may be a Cyclical Redundancy Check (CRC) value in the Ethernet message, and the CRC value is located in the FCS (Frame Check Sequence, Frame Check Sequence) field, that is, the CRC value is FCS value, the last 4 bytes of the Ethernet message is the FCS field, and this field is used to check whether the Ethernet message is modified during transmission; but the message characteristic va...

Embodiment 2

[0080] see image 3 , the device for sending a test message provided by Embodiment 2 of the present invention, the device includes: a construction module 11, a storage module 12, a sending module 13, a first statistics module 14, a first judgment module 15 and a reading module 16, wherein ,

[0081] A building block 11, configured to pre-build an Ethernet message;

[0082] In Embodiment 2 of the present invention, the Ethernet message has a message feature value that is different from other Ethernet messages. Although the message feature value is not unique, the probability of repetition is extremely small. Therefore, according to the message feature value It is sufficient to distinguish this Ethernet message from other Ethernet messages. The message feature value can be the CRC value in the Ethernet message, the CRC value is located in the FCS field, that is, the CRC value is the FCS value, and the last 4 bytes of the Ethernet message are the FCS field, which is used for ch...

Embodiment 3

[0091] see Figure 4 The method for receiving a test message provided by Embodiment 3 of the present invention includes the following steps:

[0092] S201. Receive an Ethernet message forwarded by the Ethernet device under test, where the Ethernet message is a repeated Ethernet message sent by the test device to the Ethernet device under test;

[0093] S202. Identify the packet characteristic value of the Ethernet packet;

[0094] In Embodiment 3 of the present invention, the Ethernet message has a message feature value that is different from other Ethernet messages. Although the message feature value is not unique, the probability of repetition is extremely small. Therefore, according to the message feature value It is sufficient to distinguish this Ethernet message from other Ethernet messages. The message feature value can be the CRC value in the Ethernet message, the CRC value is located in the FCS field, that is, the CRC value is the FCS value, and the last 4 bytes of t...

Abstract

The invention, which is suitable for the communication filed, provides methods and apparatuses for sending and receiving testing messages, and testing equipment. The method for sending a testing message comprises the following steps: establishing an ethernet message in advance; storing the ethernet message; sending the ethernet message to a tested ethernet device; carrying out statistics on the ethernet message sending situation; and determining whether the testing is completed; if not, reading the stored ethernet message and returning the step of sending the ethernet message to the tested ethernet device. According to the invention, the costs for ethernet message establishment and copying can be lowered, thereby improving the performance of the testing equipment.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a method, device and test equipment for sending and receiving test messages. Background technique [0002] In some application scenarios, especially during the production test of Ethernet equipment, the test equipment often needs to produce large-flow Ethernet packets for testing Ethernet equipment. The test system provided by the prior art is as follows: figure 1 shown. The test equipment in the prior art uses the protocol stack communication to manufacture the required Ethernet packet flow, and counts the sending and receiving conditions. [0003] The method for sending test packets in the prior art includes the following steps: [0004] The test equipment constructs an Ethernet message using the protocol stack; [0005] The test device sends the Ethernet packet to the Ethernet device under test; [0006] The test equipment counts the sending situation of the Ethernet ...
