Specifically, the test management device may be configured with a test case, and when a user inputs a user test operation (for example, clicks a preset button or inputs a preset code) to the test management device, the test management device may send a delay test instruction to the test execution device in response to the user test operation, where the delay test instruction may be used to instruct the test execution device to perform a delay test on the TTE network to be tested. For example, assuming that the test management device provides a human-machine control interface, a user may input a user test operation through the human-machine control interface, the test management device may determine a test case corresponding to the user test operation in response to the user test operation, and determine a test policy corresponding to the test case (for example, may include executing a test flow in a test process; for example, determining a data transmission delay between two TTE end systems to be tested, and a condition for triggering a test, etc.), and then may generate a delay test instruction according to the test policy corresponding to the test case, where the delay test instruction may include a condition for triggering a test, a sending system identifier and a receiving system identifier in a TTE network to be tested, and then may send the delay test instruction to the test execution device. It should be noted that, in an implementation manner, as shown in fig. 2, the test management device may further include a test management module, a network configuration, a test case, a TTE-tool, a test code, and the test management module may control and manage each module (for example, a board card) in the test execution device by using the network configuration, the test case, the TTE-tool, and the test code.
In this embodiment, the test execution device may be configured to respond to the delay test instruction, and acquire the transmission signal information and the reception signal information in the TTE network to be tested; and determining the transmission delay of the TTE network according to the sending signal information and the receiving signal information.
Specifically, after receiving the delay test instruction, the test execution device may respond to the delay test instruction to acquire the transmission signal information and the reception signal information in the TTE network to be tested. As an example, the TTE network to be tested may include a first TTE end system and a second TTE end system, and the first TTE end system and the second TTE end system are communicatively connected through a switch; the time delay test instruction comprises a sending system identifier and a receiving system identifier; wherein the sending system identifier is a system identifier of the first TTE end system, and the receiving system identifier is a system identifier of the second TTE end system; at this time, the test execution device may first determine, according to the sending system identifier and the receiving system identifier in the delay test instruction, that the message sending system in the TTE network to be tested is the first TTE end system corresponding to the sending system identifier, and that the message receiving system is the second TTE end system corresponding to the receiving system identifier; then, the test execution device may send a test instruction to the first TTE end system in response to the latency test instruction, so that the first TTE end system may send transmission data to the second TTE end system in response to the test instruction, so that the second TTE end system may receive the transmission data; during the process of sending transmission data from the first TTE end system to the second TTE end system, the test execution device may acquire sending signal information and receiving signal information in the TTE network to be tested, where the sending signal information may include a sending signal timestamp (i.e., a time when the first TTE end system sends the transmission data to the second TTE end system), and the receiving signal information may include a receiving signal timestamp (i.e., a time when the second TTE end system receives the transmission data from the first TTE end system), that is, the test execution device is further specifically configured to acquire a sending signal timestamp when the first TTE end system sends the transmission data and a receiving signal timestamp when the second TTE end system receives the transmission data; then, the test execution device may determine a transmission delay of the TTE network according to the sending signal information and the receiving signal information, for example, the test execution device may determine a transmission delay of the TTE network according to the sending signal timestamp and the receiving signal timestamp, and for example, a time difference between the sending signal timestamp and the receiving signal timestamp may be used as the transmission delay of the TTE network.
As shown in FIG. 1, the test execution device includes interface cards (i.e., PCIe and TTE-PXIe in FIG. 1), DIO boards (i.e., I/O in FIG. 1), a backplane, and a processor (i.e., motherboard).
The interface card may be configured to send a test instruction to the first TTE end system in response to the latency test instruction. In one implementation, an interface card may first determine, according to a sending system identifier in a delay test instruction, that a message sending system in a TTE network to be tested is a first TTE end system corresponding to the sending system identifier, and send, in response to the delay test instruction, a test instruction to the first TTE end system through a switch between the first TTE end system and a second TTE end system, where the test instruction may include a receiving system identifier and a test condition; the first TTE end system may send, in response to the test instruction, transmission data to the second TTE end system corresponding to the receiving system identifier through the switch when a test condition is satisfied, so that the second TTE end system receives the transmission data.
The DIO board card may be configured to acquire a transmission signal timestamp for the first TTE end system to transmit the transmission data and a reception signal timestamp for the second TTE end system to receive the transmission data; and sending the transmit signal timestamp and the receive signal timestamp to the processor through the backplane.

For example, as shown in fig. 2, the test management device may provide a test management function according to the transmission delay of the TTE network, that is, generate a test report according to the transmission delay of the TTE network, and store the test report, that is, the test management device may analyze the function and performance data of the TTE network to be tested according to the transmission delay of the TTE network, obtain a test result, and generate a test report; furthermore, a display operation instruction of a user can be received, and the test report is displayed in response to the display operation instruction.
Next, a specific implementation scenario of the TTE network transmission delay testing system provided in this embodiment will be described with reference to fig. 3. The testing platform (i.e. the testing execution device) and the TTE network unit UUT to be tested (i.e. the TTE network to be tested) communicate with the TTE end system card through the digital I/O module. In a basic communication test, a special TTE board card with IO in a PXI chassis (i.e. a test execution device) may be used to generate a test instruction for triggering a terminal 1 (i.e. a first TTE end system) to send transmission data and a terminal 2 (i.e. a second TTE end system) to receive the transmission data, the TTE board card forms a tested network by being connected to a TTE switch, when a message queue starts transmission, the TTE board card generates an IO signal and transmits the IO signal through a BNC interface in the terminal 1, and records timestamp information timestamp1 (i.e. a transmission signal timestamp) of the terminal 1 at the same time, when the message queue starts reception at another terminal (i.e. the terminal 2), the IO signal is generated and transmitted through a BNC interface of the terminal 2, and records timestamp information 2 (i.e. a received signal timestamp) of the timestamp when receiving, and performs a difference calculation delay on the timestamp1 and the 2, so as to realize a test of transmission delay.
