First, it should be noted that the edge server includes a plurality of ethernet interfaces, and the ethernet interfaces are respectively used for transmitting ethernet signals with a bandwidth greater than the gigabit bandwidth, such as 1PPS signals, gigabit ethernet signals, 10G/25G/40G, and the like. Referring to fig. 2, fig. 2 is a schematic structural diagram of an edge server, which includes 2 SFP interfaces and 3 RJ45 interfaces, where SFP interface 1 and RJ45 interface 1 may be used to connect device 1 and device 2, and device 1 and device 2 are other edge servers. The edge server shown IN fig. 2 uses an intel Xeon-D platform CPU, where Xeon-D is connected to SFP (Small Form-factor plug) Interface 1 through an SFP link, and is connected to a Network card chip through a PCIE (Peripheral Component Interconnect Express) link, MAC (Media Access Control sublayer protocol) IN fig. 2 is connected to RJ45 Interface 1 through an MDI (Media Dependent Interface) link, and is connected to a Buffer chip through a 1PPS IN/OUT bidirectional link, respectively, the Buffer chip is 2-way 1PPS IN/OUT, and is connected to an RS485 chip and 1 PCIE Slot, respectively, the RS485 chip converts 1PPS IN/OUT from single-ended PPS/OUT to differential, and is connected to RJ45 Interface 2, and is plugged into a Network card Slot (Interface card) IN fig. 2, network card), NIC has 1 SFP interface 2 and RJ45 interface 3.
Based on the edge server structure shown in fig. 2, the detection device of the present application includes a control chip and a plurality of ethernet interfaces connected to the control chip, and specifically, as shown in fig. 3, the detection device employs a Field Programmable Gate Array (FPGA) chip with built-in ARM Core, ZYNC-7000, which is also an embedded microprocessor, so as to save hardware cost. The ZYNC-7000 is used for storing FW for continuous testing through an SPI link external Flash, and is externally connected with a DDR (Double Data Rate SDRAM), a 50Mhz Clock GEN (Clock Generator) in a board provides a 50Mhz differential Clock for the control chip, meanwhile, the control chip is connected to an external RJ45 interface through a 1PPS link and is used for connecting a 1PPS interface of an edge server to be tested, the control chip is connected to another RJ45 interface of equipment through a gigabit Ethernet link and is used for connecting 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 and is used for connecting an SFP interface of the edge server to be tested, and the ZYNC-7000 also comprises an antenna interface which is used for plugging an antenna module and is connected to a Beidou satellite system.
When testing, the testing apparatus provided in this embodiment needs to be connected to the edge server according to the scheme shown in fig. 4, specifically, the RJ45 interface 2 in the testing apparatus is connected to the RJ45 interface 2 of the edge server through a 1PPS link, the RJ45 interface 3 in the testing apparatus is connected to the RJ45 interface 3 of the edge server through a gigabit ethernet link, and the SFP interface 2 in the testing apparatus is connected to the SFP interface 2 of the edge server through a 10G/25G/40G link. Of course, other connection methods can be adopted besides the connection method described above, and the present application is not specifically limited herein.
Generally, when time synchronization is performed, the beidou navigation system directly transmits a synchronous message to an edge server through any ethernet interface, the edge server processes the synchronous message and outputs the processed synchronous message through an ethernet interface different from an input interface, and based on the result, whether transmission delay between any two interfaces of the edge server meets a standard needs to be tested.
After the connection is completed according to the above scheme, a first interface and a second interface are selected, the first interface is used for sending a test message, and the second interface is used for receiving a feedback message, it can be understood that an interface connected with the first interface on the edge server is a first test interface, an interface connected with the second interface is a second test interface, the test device receives synchronous data sent by the beidou navigation system through an antenna to generate a test message with a timestamp, the test message is sent to the edge server through the first interface and the first test interface, and the sending time is recorded, after the edge server receives the test message, the edge server performs analysis processing to obtain interface information with the second interface, so as to determine a second interface to be tested on the edge server, and sets current routing configuration according to the above corresponding relation, so that the feedback message obtained after the test message is processed and analyzed is sent from the second test interface, And the second interface transmits the second interface back to the testing device, the testing device obtains the retention time of the test message in the edge server according to the time difference between the time of receiving the feedback message and the sending time, judges whether the retention time is within a preset time range, if the delay time of the test message in any two testing interfaces of the edge server is within the preset time range, the design of the edge server is reasonable, and the delay time of any two testing interfaces is not within the preset time range, so that the design of the edge server is unreasonable. Wherein, the preset time range can be set to be 100-200 ns. For example, suppose that the testing apparatus sends a test packet to the RJ45 interface 1 of the edge server through the RJ45 interface 1, and if the current test needs to test the transmission delay of the SFP interface 2 and the RJ45 interface 1, the port information of the SFP interface 2 is added to the test packet, so that after the edge server receives the test packet, the routing configuration is set, so as to return the feedback packet to the SFP interface 2 of the testing apparatus through the SFP interface 2.
As an optional embodiment, after calculating the delay time of the first interface and the second interface according to the sending time and the receiving time, the transmission delay testing method further includes:
and when the delay time is not within the preset time range, generating alarm prompt information, wherein the alarm prompt information comprises 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, corresponding prompt information is generated, so that the fact that the two ethernet interfaces have problems is known to designers, the reason for the failure of the positioning synchronization is facilitated, and the operation and maintenance efficiency is improved.
It can be seen that, in this embodiment, a test device is used to test transmission delays of any two ethernet interfaces of an edge server, the test device sends a test packet to the edge server through a first interface and records sending time, the test packet includes interface information of a second interface, so that the edge server configures current routing configuration according to the interface information, testing flexibility is improved, then the edge server sends a feedback packet corresponding to the test packet back to the second interface of the test device according to current routing configuration, the test device can obtain delay time between the first test interface and the second test interface in the edge server according to time of receiving the feedback packet and the previously recorded sending time, and thus whether the design of the edge server is reasonable or not is determined according to whether the delay time is exceeded or not.
