The following describes embodiments of the present application in detail.
First, a board 100 for implementing the backplane channel testing method and apparatus according to the embodiments of the present application will be described with reference to fig. 1.
The board card 100 may be a line card or a switch card.
Optionally, the board card 100 may include a processor 110, a memory 120, and a network chip 130 (e.g., a switch chip, a MAC chip, etc.).
It should be noted that the components and structures of the board 100 shown in fig. 1 are exemplary only and not limiting, and that the board 100 may have other components and structures, including interfaces for example, as desired.
The processor 110, the memory 120, the network chip 130, and other components that may be present on the board 100 are electrically connected to each other, either directly or indirectly, to enable transmission or interaction of data. For example, the processor 110, the memory 120, the plurality of boards 100, and possibly other components may be electrically connected to each other by one or more communication buses or signal lines.
The memory 120 is used for storing a program, for example, a program corresponding to a back plane channel testing method appearing later or a back plane channel testing device appearing later. Alternatively, when the back plane channel test device is stored in the memory 120, the back plane channel test device includes at least one software functional module that may be stored in the memory 120 in the form of software or firmware (firmware).
The processor 110 is configured to execute executable modules stored in the memory 120, such as software functional modules or computer programs included in the backplane channel testing device. When the processor 110 receives the execution instructions, it may execute a computer program, for example, to perform the backplane channel test method hereinafter.
Of course, the methods disclosed in any of the embodiments of the present application may be applied to the processor 110 or implemented by the processor 110.
For the board card 100 in the embodiment of the present application, the included backplane interface may be connected with interfaces of other board cards 100 to form a backplane channel. The following describes a back plane channel test method for a back plane channel provided in the present application.
Referring to fig. 2, an embodiment of the present application provides a method for testing a backplane channel of the above board card, which includes the following steps.
Step S110: and constructing a background stream message and a preset number of test messages aiming at the local end interface of the backboard channel to be tested of the board card.
As mentioned above, a plurality of boards 100 may be connected by an interface, thereby forming one to a plurality of backplane channels.
For the connection relationship between the plurality of boards 100, as an optional implementation manner, when the plurality of boards 100 are all line cards, the plurality of line cards may be directly connected through the interfaces included in each of the plurality of line cards, so as to form one to a plurality of back board channels. For example, in fig. 3, each line card includes two interfaces, the P1 interface of line card a is connected with the P2 interface of line card C, the P2 interface of line card a is connected with the P1 interface of line card B, and the P2 interface of line card B is connected with the P1 interface of line card C, thereby forming three backplane channels.
As another alternative, when a plurality of board cards 100 include both line cards and switch cards, the switch cards may be connected to each line card as intermediate nodes to form one or more backplane channels. For example, in fig. 4, the F1 interface of the switch card is connected to the P1 interface of the line card a, the F2 interface of the switch card is connected to the P1 interface of the line card B, and the F3 interface of the switch card is connected to the P1 interface of the line card C, thereby forming three backplane channels.
Each back plate channel comprises two interfaces, one is the interface of one of the two mutually connected boards, and the other is the interface of the other board. For convenience of description, in the embodiment of the present application, two concepts of a local interface and an opposite interface are defined, where after the interfaces of two boards are connected to each other to form a backplane channel, for one board, the interface of the local end is the local interface of the backplane channel that the interface of the other board participates in to form, and the interface of the other board is the opposite interface of the backplane channel. For example, in fig. 4, a backplane channel is formed between an interface F1 of the switch card and an interface P1 of the line card a, for the switch card, F1 is a local interface of the backplane channel, P1 is an opposite interface of the backplane channel, for the line card a, P1 is a local interface of the backplane channel, and F1 is an opposite interface of the backplane channel.
After the tester designates the backplane channel to be tested (in general, all the existing backplane channels in the board card can be the backplane channels to be tested, of course, in special cases, the tester can designate to test a certain or a plurality of backplane channels), one board card connected with the backplane channel to be tested can serve as a message builder to build a message for testing.
Generally, when the frame structure between the boards 100 is a direct connection type as shown in fig. 3, for each backplane channel to be tested, any one of the boards 100 included therein serves as a message builder. When the frame structure between the boards 100 includes intermediate nodes as shown in fig. 4, the boards 100 as intermediate nodes, i.e., the switch cards, serve as message constructors for each backplane channel to be tested.
The messages constructed by the board 100 acting as a message constructor include background stream messages and a preset number of test messages.
For the background stream message and the test message, a message type identifier, a destination address (a destination MAC address or a destination IP address) may be included. The message format of the background stream message and the test message may not be limited. In addition, the background stream message and the test message may further include a message serial number, an identifier (e.g., ID) of the backplane channel, and the like.
The message type is used for representing that the message is a background stream message or a test message.
The background flow message is used for forwarding back and forth in the back board channel to be tested all the time, so that the back board channel to be tested is always in a busy state, the pressure of a link is increased, the bandwidth utilization rate is improved, and the line speed forwarding performance of the back board channel to be tested under the condition of high flow pressure is tested.
Each test in the preset number of test messages is used for making a round trip in the back board channel to be tested, so that whether the performance of the back board channel to be tested passes the test is tested.
In order to enable the background stream message and the test message constructed by the board card 100 as the message constructor to have the functions, for the board card 100 as the constructor, a mapping relation table of an address and an interface is stored in advance, and when a destination address (which may be a MAC address or an IP address) of a certain message constructed by the board card 100 is consistent with a certain address (assumed to be an address 1) in the mapping relation table, the message needs to be forcedly sent out from the interface corresponding to the address (address 1) in the mapping relation table in the board card 100 as the constructor.
In addition, in each board 100, a forwarding table entry is pre-stored, in which a correspondence between each address and each board 100 is recorded, and the forwarding table entry is used to represent a destination address (may be a MAC address or an IP address) of a certain packet, and when the forwarding table is a two-layer forwarding table entry and is an IP address, the forwarding table entry is a three-layer forwarding table entry) and a certain address (assumed to be address 2) in the forwarding table entry are consistent, in the board 100 as a board that receives the packet, the packet needs to be forwarded to the board 100 corresponding to the address (address 2) in the forwarding table entry according to a normal forwarding flow.
After a mapping relation table is stored in the board 100 as a message constructor and a forwarding table item is stored in each board 100, the board 100 as a message constructor constructs a background flow message and a test message, wherein the destination address of each constructed background flow message and test message is the same, in the forwarding table item, the destination address is used for pointing to the interface corresponding to the interface of the back board channel to be tested at the local end in the mapping relation table, the destination address is used for representing the interface of the back board channel to be tested at the outlet of the board 100 as the message constructor, and simultaneously, after the opposite end interface of the back board channel to be tested receives the background flow message and the test message, the background flow message and the test message are forwarded to the local end interface of the board 100 as the message constructor according to a normal forwarding flow, namely two-layer and three-layer forwarding table lookup.
When a certain board 100 as a constructor corresponds to a plurality of back board channels to be tested, a plurality of interfaces are correspondingly arranged on the board 100, and the interfaces are respectively used as the local interfaces of the back board channels to be tested. Accordingly, when constructing a message for testing, the board 100 needs to construct multiple sets of messages corresponding to multiple back board channels to be tested. The method comprises the steps that each set of messages comprises background flow messages and a preset number of test messages, and the background flow messages and the destination addresses of the test messages of each set of messages are different. It should be noted that, the background flow message of each set of message and the destination address of the test message are used to point to the board 100 itself as the constructor in the forwarding table entry, and the background flow message of each set of message and the destination address of the test message have a mapping relationship with the corresponding to-be-tested back board channel in the mapping relationship table at the local interface on the board 100.
Still taking fig. 4 as an example, for a switch card, three interfaces included in the switch card form three backplane channels to be tested with the line card a, the line card B, and the line card C, respectively. Assuming that the switch card is used as a message constructor, a mapping relation table is stored in the switch card, when the switch card is used for constructing the message, three sets of messages need to be constructed to respectively form one-to-one correspondence with the back plate channel 1 to be tested (F1-P1), the back plate channel 2 to be tested (F2-P1) and the back plate channel 3 to be tested (F3-P1). Aiming at a background stream message and a test message corresponding to the back board channel 1 to be tested, a target MAC address of the background stream message and the test message has a mapping relation with F1 in a mapping relation table; aiming at a background flow message and a test message corresponding to the back plate channel 2 to be tested, the destination MAC address of the background flow message and the test message has a mapping relation with F2 in a mapping relation table; for the background stream message and the test message corresponding to the back board channel 3 to be tested, the destination MAC address has a mapping relation with F3 in a mapping relation table. Of course, forwarding table entries (corresponding to MAC addresses, i.e. two-layer forwarding table entries) are stored in each of the line cards a, B and C, and destination MAC addresses of the three sets of messages are used in the forwarding table entries to point to the switch card.
It should be noted that, for different back board channels to be tested, the number of the test messages corresponding to the back board channels to be tested is predetermined. Of course, the number of test messages corresponding to each backplane channel to be tested may be the same or different.
Step S120: and sending the background stream message which reaches the local end interface to the opposite end interface of the back plate channel to be tested in a forced way, and sending the preset number of test messages which reach the local end interface to the opposite end interface in a forced way.
After the board 100 constructs the background stream message and the preset number of test messages, the board 100 queries the mapping relation table, so that the background stream message and the test messages are forcedly sent out from the corresponding interfaces.
Because the destination address of the message constructed by the board 100 is the interface of the back board channel to be tested on the side of the board 100 (the local interface is opposite to the board 100 itself), after the background stream message and the preset number of test messages are acquired, the local interface forcibly sends the background stream message and the acquired preset number of test messages to the interface of the back board channel to be tested on the other board 100 (the opposite interface is opposite to the board 100 itself).
It should be noted that, after the board 100 where the opposite port is located acquires the packet, the packet is forwarded to the board 100 (i.e. the constructor of the packet) pointed by the destination address of the packet according to the destination address carried in the packet, and therefore, after the board 100 where the opposite port is located acquires the test packet and the background stream packet, the acquired test packet and background stream packet are returned to the board 100 where the local port is located.
Through the above-mentioned process, for the board 100 where the home interface is located, it acquires the background stream message and the test message again.
At this time, for the background flow message, the board card 100 where the home interface is located sends the background flow message to the board card 100 where the opposite interface is located according to the forced sending flow, and correspondingly, the board card 100 where the opposite interface is located forwards the background flow message to the board card 100 where the home interface is located according to the forwarding flow. When the subsequent board 100 with the local interface and the board 100 with the opposite interface acquire the background flow message again, the above process is repeated, so that the background flow message is always forwarded between the board 100 corresponding to the local interface and the board 100 corresponding to the opposite interface, and the back board channel to be tested is always in a busy state, the pressure of the link is increased, the bandwidth utilization rate is improved, and the performance of the back board channel to be tested in the online speed forwarding process is tested.
For the test message, when the board card 100 where the local interface is located obtains the test message from the opposite-end interface for the second time, in this embodiment, the board card 100 where the local interface is located does not forward the same test message after the board card is obtained for the second time, and at the same time, the board card 100 where the local interface is located records the same test message.
Step S130: and counting the number of the test messages returned through the opposite-end interface.
The board 100 where the home interface is located can count the number of the messages to be tested that are sent back through the board 100 where the home interface is located after delaying for a preset period of time.
In addition, as an alternative implementation manner, when a plurality of back board channels are formed between the same board 100 and other boards 100, in order to avoid that when the board 100 where the interface is located performs statistics on the test message returned, the test message corresponding to the other channels to be tested is counted by mistake into the category of the test message corresponding to the channel to be tested, and when the board 100 where the interface is located constructs the test message, the identifier of the back board channel is added into the test message, and the identifier is consistent with the identifier of the back board channel to be tested corresponding to the test message. Therefore, when the board card 100 where the home interface is located counts the test messages, the number of the test messages that are looped back through the board card 100 where the home interface is located and include the corresponding identifiers of the backplane channels to be tested can be counted.
Step S140: and determining whether the test passes or not according to the magnitude relation between the number and the preset number.
Optionally, for a certain back board channel to be tested, when the number of the messages to be tested, which are counted by the board 100 and sent back by the board 100 where the opposite end of the back board channel to be tested is located, is consistent with the number of the test messages with a preset number, which are constructed for the back board channel to be tested, the board 100 where the local end interface is located can determine that the test of the back board channel to be tested passes, otherwise, the test of the back board channel to be tested does not pass.
In addition, as an alternative embodiment, each test packet constructed by the board 100 where the home interface is located further includes a Cyclic Redundancy Check (CRC). Before the board 100 where the local interface is located sends out the test messages, the network chip included in the board records the CRC of each test message in the sending state, for example, a corresponding relationship is established between the message serial number and the CRC. When the board 100 where the local interface is located acquires the test message returned by the board 100 where the opposite interface is located, the CRC of the test message in the receiving state is recorded again, whether the CRC corresponding to the same message serial number is equal is checked, and when an unequal condition is checked, the network chip automatically adds a register for recording CRC check errors. In this embodiment, when the number of the test messages counted by the board 100 where the home interface is located is equal to the preset number and the value of the register for recording the number of errors of the cyclic redundancy check code is zero, the board 100 determines that the test of the back board channel to be tested corresponding to the test message passes.
Of course, after determining the test result, the board 100 where the home interface is located may stop forwarding the background flow message.
According to the back board channel testing method, the background flow messages and the preset number of the testing messages are built, then the background flow messages are always forwarded back and forth in the back board channel to be tested, and the preset number of the testing messages are made to back and forth once in the back board channel to be tested. And then, determining whether the test passes or not by comparing the magnitude relation between the number of the returned test messages and the preset number. In the testing process of the backboard channel, a third-party tester is not needed, in addition, the tester designates the channel to be tested and then automatically tests, and for the tester, the tester does not need to repeatedly modify the testing parameters according to different testing objects, so that the testing complexity is simplified.
