It should be noted that in this document, relational terms such as "first" and "second" and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
The switch testing method provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, an embodiment of the present application provides a method for testing a switch, which is applied to a switch in a vehicle, where the switch may be used to connect an operating system of the vehicle with ethernet, so that the vehicle may interact with a server of a vehicle management platform, other vehicles, road Side Units (RSU), and the like.
The switch testing method provided by the application can comprise the following steps:
s101, establishing communication connection between a first physical port and test equipment;
S102, under the condition that a first physical port receives a test data stream sent by test equipment, the test data stream is sent from the first physical port to a preset second physical port along a first preset transmission path of the test data stream, and the test data stream is reversely sent from the second physical port to the first physical port, wherein the first preset transmission path comprises at least one test port;
s103, obtaining the first data receiving quantity of the test data stream received by each test port each time, and sending the first data receiving quantity to the test equipment so that the test equipment displays the first data receiving quantity of each test port.
The first physical port and the second physical port are ports in the switch. For convenience of testing, the first physical port and the second physical port may be sockets exposed on the housing of the switch, so as to facilitate a user to realize physical connection of the test device and the physical port through the communication wire. The second physical port may be set to a loop back (loopback) mode such that the second physical port may return the test data stream received from the upstream port as it is to the upstream port. Any two exposed sockets in the switch may be selected as the first physical port and the second physical port.
The test data stream includes a plurality of packets, the packets including a plurality of frames. The user inputs various test data stream attribute information in the test equipment, wherein the test data stream attribute information can comprise the size of frames and the number of packets, the test equipment can generate a test data stream according to the test data stream attribute information input by the user and send the test data stream to the switch, and a first physical port of the switch receives the test data stream. The test data stream carries a first preset transmission path, namely, a port address for receiving the test data stream is defined, and the port needs to forward the test data to another port address, so that the switch can forward the test data stream among a plurality of ports to count the data receiving amount corresponding to each port. In the application, the first preset transmission path comprises a first physical port, a test port P1-a test port Pn, a second physical port, a test port Pn-a test port P1, a first physical port and test equipment which are sequentially arranged, wherein n is more than or equal to 1. The test ports P1 to Pn are a plurality of different ports in the switch, and the test ports may be ports disposed in a casing of the switch, and since the ports are not exposed to the casing, communication connection with other devices cannot be directly established through wires. Data transmission can be conducted between the first physical port and the test port based on sgmii protocol, and data transmission can be conducted between the second physical port and the test port based on sgmii protocol.
The first data receiving amount is the size of the test data stream received by the test port. The first data reception amount corresponding to the test port may be stored in a register of the switch. After the switch completes the forwarding step of the test data stream along the test path, the first physical port sends the test data stream to the test device, and the switch may send the first data reception amount to the test device. Of course, the test device may also send an acquisition request to the switch after receiving the test data stream sent by the first physical port, where the switch feeds back the first data receiving amount to the test device according to the received acquisition request.
It will be understood by those skilled in the art that the size of the test data stream sent by the test device to the first physical port is known, the size of the test data stream received by the test device may be obtained by monitoring the monitoring module in the test device, and the first data receiving amount of the test data stream received by each test port is known, so that the user may determine the data forwarding performance of the test port, that is, the frame loss condition of the test port according to the change of the size of the test data stream in the transmission process. The size of the test data stream can be set so as to pass through the frame loss condition of the test ports corresponding to the test data streams with different sizes.
For example: in the embodiment shown in fig. 2, the test device sends a test data stream of 1000000 bytes to the first physical port, the first physical port H1 sends a test data stream to the test port P1, the first data receiving amount corresponding to the test port P1 is 1000000 bytes, the test port P1 sends a test data stream to the test port P2, the first data receiving amount corresponding to the test port P2 is 998500 bytes, the test port P2 sends a test data stream to the second physical port H2, the second physical port H2 sends a test data stream to the test port P2, the first data receiving amount corresponding to the test port P2 is 998500 bytes, the test port P2 sends a test data stream to the test port P1, the first data receiving amount corresponding to the test port P1 is 998500 bytes, the test port P1 sends a test data stream to the first physical port H1, the test data stream sent by the test port P1 is monitored to the test device, and the test device obtains a received test data stream of 998500 bytes. By comparing the changes of the sizes of the test data streams, it is known that the test port P1 has a problem of frame loss in the process of forwarding the test data stream sent by the first physical port H1 to the test port P2.
In the switch testing method provided by the embodiment, by establishing communication connection between the first physical port and the testing device, the first physical port can receive the test data stream sent by the testing device, and the second physical port can send the received test data stream to the sending port in a loop; the first data receiving quantity of the test data stream received by the test port each time can be obtained by sending the test data stream among at least one test port, the first physical port and the second physical port along the first preset transmission path, and the data forwarding performance of the test port can be evaluated by sending the first data receiving quantity to the test equipment, so that a user or the test equipment can obtain the change of the size of the transmission of the test data stream among the ports through the analysis of the first data receiving quantity, and the problem of frame loss of the test port is determined through the change.
In some embodiments, after obtaining the first data reception amount of each test port, further comprising:

s302, generating frame loss information according to the first change value.
Adjacent test ports are adjacent on the transmission path, not adjacent in physical location. For example, the first test port P1 transmits a test data stream to the second test port P2, and the first test port P1 and the second test port P2 are adjacent on the transmission path. For example, the second test port P2 sends a test data stream to the second physical port H2, and the second physical port H2 sends a test data stream back to the second test port P2, and then the second test port P2 located at the front end of the second physical port H2 and the second test port P2 located at the rear end of the second physical port H2 are adjacent on the transmission path.
In this embodiment, the switch may calculate a first change value according to the first data receiving amount of each test port, determine whether a frame loss phenomenon occurs according to the first change value, and generate frame loss information to determine an occurrence position of the frame loss phenomenon. The frame loss information may include an identification of a test port on which the transmission frame loss occurred, a lost frame number, and the like. The switch may also send the frame loss information to the value test device for further analysis by the test device.
In some embodiments, S302 includes:
In the case where the first variation value is greater than 0, frame loss information about the test port located at the front end is generated.
And under the condition that the first variation value is equal to 0, the first data receiving quantity received by the adjacent test ports is not changed, and the test ports at the front end completely forward the received test data stream. When the first variation value is greater than 0, the magnitude of the first data receiving amount received by the adjacent test port is changed, and frame loss information about the test port at the front end is generated.
Referring to fig. 2 and fig. 4, in some embodiments, after obtaining the first data receiving amount of each test port, the method further includes:
S401, acquiring second data receiving quantity of the first physical port and the second physical port for receiving the test data stream each time;
S402, calculating second variation values of second data receiving quantity corresponding to the first physical port and first data receiving quantity of the test port in adjacent first physical ports and test ports on a first preset transmission path;
s403, calculating a third variation value of a second data receiving amount corresponding to the second physical port and a first data receiving amount of the test port in the adjacent second physical port and test port on the first preset transmission path;
s404, generating frame loss information according to the second change value and the third change value.
The adjacent second physical port and test port are adjacent on the transmission path, not adjacent in physical location. For example, the second test port P2 sends a test data stream to the second physical port H2, and the second physical port H2 sends a test data stream back to the second test port P2, then the second test port P2 located at the front end of the second physical port H2 is adjacent to the second physical port H2 on the transmission path, and the second physical port H2 is adjacent to the second test port P2 located at the back end.
The switch can determine whether the first physical port and the test port at the front end of the first physical port send the test data stream to generate frame loss according to the second change value, and generate frame loss information. The switch can determine whether the frame loss phenomenon occurs in the test data stream sent by the first physical port and the test port positioned at the front end of the first physical port according to the second change value, and generate frame loss information. The frame loss information may further include identification identifiers of the first physical port and the second physical port where the frame loss phenomenon occurs.
In some embodiments, S404 includes:
Generating frame loss information about the first physical port in the case that the second variation value is greater than 0;
Generating frame loss information about the test port corresponding to the second variation value under the condition that the second variation value is smaller than 0;
generating frame loss information about the second physical port in the case that the third variation value is greater than 0;
And generating frame loss information about the test port corresponding to the third variation value under the condition that the third variation value is smaller than 0.
And under the condition that the second variation value is equal to 0, the sizes of the test data streams received by the adjacent test ports and the first physical ports are unchanged, and the test ports positioned at the front ends or the first physical ports in the adjacent test ports or the first physical ports completely forward the received test data streams. And under the condition that the second variation value is larger than 0, the sizes of the test data streams received by the adjacent test ports and the first physical ports are changed, and frame loss information about the first physical ports is generated. And under the condition that the second variation value is smaller than 0, the sizes of the test data streams received by the adjacent test ports and the first physical ports are changed, and frame loss information about the test ports is generated. The setting principle of the third variation value is similar to that of the second variation value, and will not be described in detail here.
In some embodiments, the test method further comprises:
establishing communication connection between the second physical port and the test equipment, and setting the first physical port as a loop-back mode;
Under the condition that the first physical port receives the test data stream sent by the test equipment, the test data stream is sent from the second physical port to the first physical port along a second preset transmission path of the test data stream, the test data stream is reversely sent from the first physical port to the second physical port, and the second transmission path and the first transmission path comprise the same test port;
And acquiring a third data receiving amount of each test port, and transmitting the third data receiving amount to the test equipment.
The second transmission path and the first transmission path comprise the same test port, and the relative sending and receiving relation of each test port in the first transmission path and the second transmission path can be adjusted so as to flexibly test whether the same test port forwards the test data stream to different test ports or not has the frame loss phenomenon.
In S501 and S101, the functions of the first physical port and the second physical port are switched to each other, so that the data transceiving performance between the second physical port and the test device can be tested. And the frame loss information can also be generated according to the third data receiving quantity of the test port positioned at the front end and the third variation value of the third data receiving quantity of the test port positioned at the rear end in the adjacent test ports on the second preset transmission path.
