Please refer to FIG. 1. FIG. 1 is a flow chart of the steps of a transmission delay testing method of an edge server provided by the present application. The transmission delay testing method includes:

S101: Determine any two different Ethernet interfaces as the first interface and the second interface;

S102: Send a test message to the first test interface of the edge server through the first interface, and record the sending time, the test message includes the interface information of the second interface, so that the edge server can adjust the current routing configuration according to the interface information, and send the test message The corresponding feedback message is sent back to the second interface through the second test interface of the current routing configuration;

S104: When the delay time is not within the preset time range, it is determined that the design of the edge server is unreasonable.

First of all, it needs to be explained that the edge server includes multiple Ethernet interfaces, which are respectively used to transmit 1PPS signal, Gigabit Ethernet signal, 10G/25G/40G and other Ethernet signals with a bandwidth greater than Gigabit. The transmission delay test is actually a test of the transmission delay of any two different external network interfaces of the edge server. Referring to Figure 2, Figure 2 is a schematic structural diagram of an edge server, including 2 SFP interfaces and 3 RJ45 interfaces, wherein SFP interface 1 and RJ45 interface 1 can be used to connect device 1 and device 2, and device 1 and Device 2 is the other edge server. The edge server shown in Figure 2 adopts Intel's Xeon-D platform CPU, wherein, Xeon-D is connected to SFP (Small Form-factor Pluggable, miniaturized hot-swappable module) interface 1 through SFP link, through PCIE (Peripheral ComponentInterconnect Express, high-speed serial computer expansion bus) link is connected to a network card chip, MAC (Media Access Control, media access control sublayer protocol) in Figure 2, MAC is connected through MDI (Media DependentInterface, medium dependent interface) link Connect to RJ45 port 1, connect to a Buffer chip via 1PPS IN/OUT two-way link through Xeon-D and MAC respectively, and the Buffer chip outputs 2 channels of 1PPS IN/OUT, respectively connected to the RS485 chip and 1 PCIE Slot slot, RS485 The chip converts 1PPS IN/OUT from single-ended to differential, and connects it to RJ45 interface 2, and inserts a network card into the PCIESlot. The NIC (Network Interface Controller, network card) in Figure 2 has an SFP interface 2 and RJ45 interface 3.

Based on the edge server structure shown in Figure 2, the detection device of the present application includes a control chip and multiple Ethernet interfaces connected to the control chip. The FPGA (Field Programmable Gate Array, programmable logic device) chip with built-in ARM Core is also an embedded microprocessor, which saves hardware costs. ZYNC-7000 is connected with external Flash via SPI link to store FW for continuous testing, external DDR (Double Data Rate SDRAM, double data rate SDRAM), on-board 50Mhz Clock GEN (Clock Generator, clock generator) Provide a 50Mhz differential clock to the control chip, and at the same time, the control chip is connected to the external RJ45 interface through a 1PPS link, which is used to connect to the 1PPS interface of the edge server to be tested. The control chip is connected to the device’s Another RJ45 interface is used to connect an Ethernet interface of the edge server to be tested. The control chip is connected to an external SFP interface through a 10G/25G/40G link, which is used to connect to the SFP interface of the edge server to be tested. It also includes a Antenna interface, used to insert the antenna module to connect to the Beidou satellite system.

When testing, the test device provided by this embodiment needs to be connected to the edge server according to the scheme shown in Figure 4. Specifically, the RJ45 interface 2 in the test device is connected to the RJ45 interface 2 of the edge server through a 1PPS link. The RJ45 interface 3 in the test device is connected to the RJ45 interface 3 of the edge server through a Gigabit Ethernet link, and the SFP interface 2 in the test device is connected to the SFP interface 2 of the edge server through a 10G/25G/40G link. Of course, in addition to the above-mentioned connection methods, other connection methods may also be used, and this application does not make specific limitations here.

Generally, when performing time synchronization, the Beidou navigation system directly transmits the synchronization message to the edge server through any Ethernet interface, and the edge server processes the synchronization message and outputs it through an Ethernet interface different from the input interface. Based on this , it is necessary to test whether the transmission delay between any two interfaces of the edge server meets the standard.

After connecting according to the above scheme, select the first interface and the second interface. The first interface is used to send test messages, and the second interface is used to receive feedback messages. It can be understood that the edge server is connected to the first interface The interface connected to the second interface is the first test interface, and the interface connected to the second interface is the second test interface. The test device receives the synchronization data sent by the Beidou navigation system through the antenna, generates a test message with a time stamp, and sends the test message to Send it to the edge server through the first interface and the first test interface, and record the sending time. After receiving the test message, the edge server will analyze and process it to obtain the interface information with the second interface, so as to determine the edge server. The second interface to be tested sets the current routing configuration according to the above-mentioned corresponding relationship, so that the feedback message obtained after the test message is processed and analyzed is transmitted back to the test device by the second test interface and the second interface, and the test device receives the feedback according to The time difference between the time of the message and the sending time is used to obtain the retention time of the test message on the edge server, and judge whether the retention time is within the preset time range. If the delay time of the test message on any two test interfaces of the edge server is If the delay time of any two test interfaces is not within the preset time range, it means that the design of the edge server is reasonable. Wherein, the preset time range may be set at 100-200 ns. For example, assume that the test device sends a test message to the RJ45 interface 1 of the edge server through RJ45 interface 1. If the current test needs to test the transmission delay between SFP interface 2 and RJ45 interface 1, the port information of SFP interface 2 is added to the test report. In this article, after the edge server receives the test message, it sets the routing configuration so that the feedback message can be returned to the SFP interface 2 of the test device through its SFP interface 2 .

When the delay time is not within the preset time range, alarm prompt information is generated, and the alarm prompt information includes interface information of the second interface and interface information of the first interface.

Specifically, if the delay time of any two Ethernet interfaces is no longer within the preset range, a corresponding prompt message is generated to inform the designer that there is a problem with the two Ethernet interfaces, which facilitates locating the cause of synchronization failure and improves operation and maintenance efficiency .

It can be seen that in this embodiment, the transmission delay of any two Ethernet interfaces of the edge server is tested by the test device. The test device sends a test message to the edge server through the first interface, and records the sending time. The test message includes the first The interface information of the second interface, so that the edge server configures the current routing configuration according to the interface information to improve the test flexibility, and then the edge server returns the feedback message corresponding to the test message to the second interface of the test device according to the current routing setting, and the test The device can obtain the delay time between the first test interface and the second test interface in the edge server according to the time of receiving the feedback message and the previously recorded sending time, so as to determine whether the design of the edge server is reasonable according to whether the delay time exceeds the limit .
