First embodiment
The applicant researches and discovers that the distributed equipment is composed of a main control board card and a line card, wherein the main control board card is connected with the line card through an ethernet chip, please refer to fig. 1, and fig. 1 is a schematic connection diagram of the main control board card and the line card, and the main control board card and the line card perform data communication through sending and receiving messages. In the development and debugging stage of the existing distributed equipment, because a bottom driver or hardware is not stable enough, the numbers of two or more line cards obtained from a system are often the same, so that the line cards are in failure in the loading process or after the line cards are loaded, but the difficulty in troubleshooting and determining the failure is very high, and a large amount of manpower and material resources are consumed.
In order to solve the above problem, a first embodiment of the present invention provides a method for detecting a serial number of a line card, where an execution main body of the method is a main control board card.
Referring to fig. 2, fig. 2 is a schematic flow chart of a method for detecting a serial number of a line card according to a first embodiment of the present invention, where the method includes the following specific steps:
step S11: the main control board card sends keep-alive messages to the line cards respectively.
In this embodiment, the main control board card may send the keep-alive message when the main control board card does not perform data message transceiving with the line card. The main control board card and the line card establish interactive connection, but data interaction does not exist all the time, some connections can actively release the connection after the data interaction is finished, and some connections cannot, so that in a long-time period without data interaction, various accidents such as power failure, crash, abnormal restart and the like can occur to both interaction sides.
Step S12: the line card receives the keep-alive messages sent by the main control board card, and response messages are returned to the main control board card aiming at the keep-alive messages, wherein the response messages comprise response serial numbers and line card numbers, the response serial numbers in the response messages successively returned by the line cards with the same line card number are different, and the line card numbers are the marks which are distributed by the line cards and used for representing the identity of the line cards.
Step S13: and the main control board card receives a response message returned by each line card aiming at the keep-alive message.
In this embodiment, the response message returned by the line card and the keep-alive message sent by the main control board card are of the same message type.
In the design and implementation of the board card communication of the distributed device, generally, the keep-alive message generally carries a sequence number, and in this embodiment, the sequence number in the acknowledgement message is an acknowledgement sequence number. Meanwhile, the number used for representing the identity of the line card should be a unique number corresponding to one line card in a non-failure situation, and the number may be, but is not limited to, a number assigned to each line card by other processing devices in the master control board or the distributed device when the line card is started.
Step S14: the main control board card determines that the line card number or the response serial number of the received response message does not accord with the preset rule, and determines that the line card number or the response serial number which does not accord with the response message of the preset rule is repeated.
The preset rule in this embodiment may be adjusted according to different processing and determining modes of the main control board card and the line card for the response serial number.
The line card number detection method provided by the embodiment of the invention sends the keep-alive message to the line card through the main control board card and receives the response message returned by the line card, determines whether the fault with repeated line card numbers exists or not based on the response serial number in the response message, does not need other special fault determination hardware to participate, reduces the hardware requirement of fault determination, simultaneously enables the fault determination with repeated line card numbers to be simpler and faster, and improves the line card number detection efficiency.
As an optional implementation manner, the response serial number in the response message in step S12 may be a global variable uniquely determined by the line card, a value of the global variable changes according to a preset rule after each response message is sent by the line card, and response serial numbers in response messages successively returned by line cards with the same number are different.
Corresponding to the above steps, the step S14 of determining that the line card number or the response sequence number of the received response packet does not meet the preset rule includes: and when the received response serial number is repeated with the response serial number of the response message of the number of the same line card received before, determining that the line card number or the response serial number of the received response message does not accord with a preset rule.
For example, the preset rule in step S12 in the above embodiment may be, but is not limited to, that each time the line card sends a response message, the response sequence number of the response message when the response message is sent next time is increased by 1, that is, when the response sequence number of the response message sent last by the line card with line card number 5 is 56, the response sequence number of the response message sent this time is 57. Further, in step S14, when the response message received by the main control board card receives a response serial number 57 that is less than or equal to the response serial number predicted according to the preset rule, and the line card number that transmits the response message is 5, it is determined that there is another line card that also obtains the line card number 5, and the line card that transmits the response serial number that is less than or equal to 57 is a line card that has a line card number repeat failure.
It should be understood that, in addition to increasing by 1 with each transmission of the response message, the response sequence number may be incremented or decremented by other fixed values each time, or may be increased or decreased in an equal-ratio series, or the like.
According to the embodiment, after the line card receives the keep-alive message, the response serial number which is changed according to the preset rule after each response message is sent is added to the response message returned to the control board card, the main control board card receives the response message, when the response serial number is the same as the response serial number of the previous collinear card, the main control board card determines that the serial number of the corresponding line card is repeated, fault determination is carried out based on the response serial number sent by each line card, the determination accuracy rate is improved, meanwhile, the line card increases and decreases the global variable of the response serial number, the operation burden of the main control board card is dispersed, and the determination efficiency of the repeated fault of the serial number of the line card is improved.
As an optional implementation manner, the response sequence number in step S12 may be determined according to a keep-alive message sent by the main control board, specifically, the keep-alive message includes a keep-alive sequence number, the keep-alive sequence number is a global variable determined by the main control board, and a value of the global variable changes after the main control board sends one keep-alive message each time.
Corresponding to the above step S13, the step S14 of this embodiment of "determining that the line card number or the response serial number of the received response packet does not meet the preset rule" includes: and when the response serial numbers and the line card numbers of the at least two received response messages are the same, determining that the line card numbers or the response serial numbers of the received response messages do not accord with a preset rule.
It should be understood that the change rule of the saved serial number in step S12 may be to increment or decrement by a fixed value each time, or to increase or decrease in an equal-ratio series, etc.
For example, in step S11 of the above embodiment, if the keep-alive sequence number in the keep-alive message sent by the main control board to the line card with the line card number 21 this time is 12, then the response sequence number in the response message returned by the line card with the line card number 21 in step S12 is also 12, and if the main control board receives a response message with another line card number 21 and the response sequence number 12, it indicates that the line card number of another line card is also 21.
According to the embodiment, whether the fault of the line card number repetition exists is judged through the fact that whether the main control board card receives the line card numbers of the plurality of response messages and the response serial numbers are the same, the global variable does not need to be set, the operation difficulty is reduced, and therefore the higher judging efficiency of the fault of the line card number repetition is obtained.
As an optional implementation manner, when the main control board may determine the number that each line card should obtain, the response sequence number in step S12 may be determined according to the corresponding line card number of each line card in the keep-alive message sent by the main control board and the keep-alive sequence number. In this embodiment, the keep-alive message includes a mapping table of a line card number and a keep-alive sequence number of each line card, each line card number corresponds to a unique keep-alive sequence number, and a response sequence number in the response keep-alive message is the same as a keep-alive sequence number in the received keep-alive message.
Corresponding to the above step S13, the step S14 of this embodiment of "determining that the line card number or the response serial number of the received response packet does not meet the preset rule" includes: and when the same response serial number is received, determining that the line card number or the response serial number of the received response message does not accord with a preset rule.
For example, in this embodiment, the mapping table in the same keep-alive message sent by step S11 to all line cards includes: line cards with different line card numbers return sequence numbers corresponding to the line card numbers of the line cards to the main control board card as response sequence numbers, namely the response sequence number in a response message returned by the line card with the line card number 15 is 101, the response sequence number in a response message returned by the line card with the line card number 16 is 102, and the response sequence number in a response message returned by the line card with the line card number 16 is 103 in step S12. When the main control board card receives two or more response messages with response serial numbers of 101, it is determined that the corresponding number of line cards obtain the same line card number 15.
In the embodiment, the same keep-alive message containing the mapping table of the line card number and the keep-alive sequence number is sent to each line card through the main control board card, whether the fault with the repeated line card number exists is determined based on the response message returned by the line card by comparing with the mapping table, and the main control board card only needs to broadcast and send the same keep-alive message, so that the fault judgment accuracy is ensured according to the mapping table, and meanwhile, the operation burden of the main control board card is reduced.
As an optional implementation manner, whether there are other line cards with the same number as the line card of the line card itself may also be determined by the line card itself, and the main execution body of the line card number detection method is the line card. Referring to fig. 3, fig. 3 is a diagram illustrating another line card number detection method according to a first embodiment of the present invention, which includes the following specific steps:
step S21: the line card receives keep-alive messages sent by the main control board card, the keep-alive messages comprise main control board card numbers and a learning bitmap, the main control board card numbers are marks which are distributed by the main control board card and used for representing the identity of the main control board card, and values of bits corresponding to the line card numbers in the learning bitmap are used for representing whether the line card sends response messages to the main control board card before the keep-alive messages are received.
Step S22: when the keep-alive message is the first keep-alive message received by the line card from the main control board card, and the value of the bit corresponding to the line card number in the learning bitmap indicates that the line card sends a response message to the main control board card before receiving the keep-alive message, the number of the line card corresponding to the response message of which the response serial number does not accord with the preset rule is determined to be repeated.
The learning bitmap in this embodiment is a field newly opened up in the keep-alive message, and if the main control board card receives the keep-alive message 1 of the line card B, the value of the bit corresponding to the line card number of the line card B in the learning bitmap sent to the keep-alive message of the line card B by the subsequent main control board card indicates that the line card has sent the keep-alive message to the main control board card before receiving the keep-alive message 1, and it is determined that the line card number of the line card corresponding to the response message whose response sequence number does not conform to the preset rule is repeated. The value of the bit corresponding to the learning bitmap may be, but is not limited to, 0 indicating that the line card has not sent the keep-alive message to the main control board before receiving the keep-alive message, and 1 indicating that the line card has sent the keep-alive message to the main control board before receiving the keep-alive message.
It should be understood that when the line card receives the keep-alive message sent by the main control board card for the first time, the bit corresponding to the line card number of the line card and the learning bitmap of the keep-alive message is not assigned, and whether a line card with the same number as the line card has responded the keep-alive message to the main control board card can be judged based on whether the bit corresponding to the line card number is assigned.
It should be understood that, in this embodiment, when it is determined that a line card has a fault with a duplicate line card number, the line card is not loaded, so that the line card does not send messages (e.g., data messages) other than the keep-alive messages, thereby preventing the influence caused by the fault from being expanded.
In the line card number detection method provided by this embodiment, the master control board adds the learning bitmap in the keep-alive message, so that the line card can automatically determine whether the line cards with the same number as other line cards have communicated with the master control board based on the learning bitmap in the received keep-alive message, and disperse the determination operation task to each line card, thereby improving the failure determination efficiency.
