Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.

In a communication networking, when one of a plurality of sending links and receiving links between an optical module and a processor fails, the operation of the optical module is abnormal. At this time, the optical module needs to be repaired or replaced so that the operation of the optical module is recovered to normal.

In order to solve the above problem, an embodiment of the present application provides a message transmission method. In the method, a processor detects whether a fault link exists in a plurality of links between the processor and an optical module. And when a fault link exists, the processor modifies a message transmission mechanism, and based on the modified message transmission mechanism, the processor and the optical module use a normal link to transmit messages. Therefore, when the link of the optical module fails and waits for maintenance or replacement of the optical module, the optical module can still work, and the probability of network disconnection accidents caused by the failure of the link of the optical module is reduced.

The following describes in detail a message transmission method provided in the embodiment of the present application, with reference to a specific embodiment.

As shown in fig. 1, fig. 1 is a first flowchart of a message transmission method provided in this embodiment, where the method is applied to a processor, and multiple links exist between the processor and an optical module. The message transmission method comprises the following steps.

S101, whether a fault link exists in a plurality of links between the processor and the optical module is detected.

The plurality of links between the processor and the optical module include a plurality of receiving links and/or a plurality of transmitting links. Here, the receive chain and the transmit chain refer to the receive chain and the transmit chain of the processor. The receiving link of the processor is used for receiving the message sent by the optical module, and the receiving link of the processor is equivalent to the sending link of the optical module. The sending link of the processor is used for sending messages to the optical module, and the sending link of the processor is equivalent to the receiving link of the optical module. The receiving link and the transmitting link both refer to the receiving link and the transmitting link of the processor, and are not described in detail later.

Taking the QSFP28 packaged high-speed optical module as an example, a 50G high-speed optical module has 2 groups of receiving links and 2 groups of transmitting links, and a 100G high-speed optical module has 4 groups of receiving links and 4 groups of transmitting links. The transmitting chain may also be referred to as an electrical signal transmitting chain, and the receiving chain may also be referred to as an electrical signal receiving chain.

The QSFP28 packaged high-speed optical module is only an example, and the optical module is not limited.

In this embodiment, the processor may periodically detect whether a failed link exists in the plurality of links between the processor and the optical module. The processor may also detect whether a faulty link exists in the plurality of links between the processor and the optical module after receiving the detection instruction. The detection instruction may be directly input into the processor by the user, or may be acquired from another device, which is not limited herein.

S102, when a fault link exists in the plurality of links, modifying a message transmission mechanism so that the modified message transmission mechanism indicates that the processor and the optical module transmit messages through other links, wherein the other links are links except the fault link in the plurality of links.

The message transmission mechanism is used for indicating which links are adopted by the processor and the optical module to transmit messages.

In the embodiment of the application, when the processor detects that a fault link exists in the plurality of links, the message transmission mechanism is modified, the modified message transmission mechanism indicates that the processor and the optical module transmit a message through a normal link except the fault link in the plurality of links, that is, the modified message transmission mechanism indicates that the processor and the optical module transmit a message through a normal link.

If the processor does not detect that a faulty link exists in the plurality of links, the processor may not perform any processing, and return to re-execute step S101.

Based on the modified message transmission mechanism, the processor and the optical module use a normal link to transmit the message. Therefore, when the link of the optical module breaks down and waits for maintenance or replacement of the optical module, as long as a group of normal links exist between the processor and the optical module, the message between the processor and the optical module can be continuously transmitted, and the probability of network failure accidents caused by the link failure of the optical module is reduced.

In the embodiment of the application, when a fault link is detected, a message transmission mechanism is modified, and based on the modified message transmission mechanism, the processor and the optical module use a normal link to transmit a message. This strives for a certain time for repair or replacement of the light module.

In most cases, the link cannot be fully loaded, and particularly, the link load at night is smaller, so that in the technical scheme provided by the embodiment of the application, although part of the link is removed, the transmission rate of the link is reduced, but a certain communication requirement can still be met. Therefore, the problem of serious network disconnection can be avoided, and the maintenance of the communication network is facilitated.

In an embodiment of the present application, the plurality of links between the processor and the optical module include a plurality of receiving links, and the receiving links are used for receiving messages sent by the optical module. In this case, an embodiment of the present application further provides a message transmission method, as shown in fig. 2. In this method, step S101 may be refined into steps S1011 and S1012.

S1011, detecting whether there is a receiving link with an abnormal electrical signal in the plurality of receiving links between the processor and the optical module.

S1012, if the electrical signal of the first receiving link is detected to be abnormal, determining that the first receiving link is faulty.

In the embodiment of the present application, the number of the first receiving links may be one or more.

In the circuit, a receiving side of the link can sense whether the electrical signal of the link is abnormal or not. For example, the receiving side can perceive whether the level amplitude of the link satisfies a minimum requirement, and can perceive whether there is an idle signal flow in the link. A link failure may be determined if the level amplitude of the link does not meet a minimum requirement and/or if there is no idle signal flow in the link. Otherwise, the link is determined to be normal.

For the receiving link in the embodiment of the present application, the receiving side is the processor, that is, the processor may sense whether the receiving link fails. The processor can detect whether the abnormal receiving link of the electric signals exists in the plurality of receiving links in real time. If the electrical signals of one or more receiving chains (such as a first receiving chain) in the plurality of receiving chains are abnormal, the first receiving chain is determined to be in failure.

If there is no abnormal electrical signal receiving link among the plurality of receiving links, the processor may determine that there is no faulty receiving link, and then return to step S1011.

In the technical scheme provided by the embodiment of the application, the processor can conveniently and quickly determine the faulty receiving link by detecting the electric signal. Therefore, as long as a group of normal receiving links exist between the processor and the optical module, the messages between the processor and the optical module can be continuously transmitted, and the probability of network failure accidents caused by the failure of the receiving links of the optical module is reduced.

Based on the message transmission method shown in fig. 2, an embodiment of the present application further provides a message transmission method, as shown in fig. 3. In this method, step S102 may be refined into steps S1021 and S1022.

And S1021, modifying a first message transmission mechanism in the processor, so that the modified first message transmission mechanism indicates the processor to receive messages sent by the optical module through other receiving links, wherein the other receiving links are receiving links except the first receiving link.

In this embodiment, the first message transmission mechanism is a message transmission mechanism in a processor. The message transmission mechanism instructs the processor to receive the messages sent by the optical module through which receiving links.

Upon detecting a failure of the first receive link, the processor modifies the first message transmission mechanism. The modified first message transmission mechanism instructs the processor to receive messages sent by the optical module through other receiving links. That is, based on the modified first message transmission mechanism, the processor receives the message sent by the optical module through the normal receiving link, thereby ensuring the communication between the processor and the optical module.

S1022, modify the second message transmission mechanism in the optical module, so that the modified second message transmission mechanism instructs the optical module to send a message to the processor through another receiving link.

In this embodiment of the present application, the second message transmission mechanism is a message transmission mechanism in an optical module. The message transmission mechanism instructs the optical module through which receive links to send messages to the processor.

When the failure of the first receiving link is detected, the processor modifies the first message transmission mechanism and simultaneously modifies the second message transmission mechanism in the optical module. The modified second message transmission mechanism instructs the optical module to send messages to the processor through other receiving links. That is, based on the modified second message transmission mechanism, the optical module sends a message to the processor through the normal receiving link, so that the communication between the processor and the optical module is ensured.

In the embodiment of the present application, the execution sequence of steps S1021 and S1022 is not limited.

In one embodiment of the application, upon detecting a failure of the first receive link, the processor may send a notification message to the optical module over an Inter-Integrated Circuit (IIC) bus, the notification message instructing the optical module to modify the second messaging mechanism. And the optical module modifies a second message transmission mechanism in the optical module based on the notification message, and the modified second message transmission mechanism instructs the optical module to send a message to the processor through other receiving links.

For example, the link structure between the optical module and the processor is shown in fig. 4. Fig. 4 takes a 100G high-speed optical module packaged by QSFP28 as an example, and the links between the optical module and the processor include 4 receiving links, namely receiving link 1, receiving link 2, receiving link 3, and receiving link 4.

The processor detects whether the abnormal receiving link of the electric signals exists in the receiving links 1-4 in real time. And if the electric signal of the receiving link 2 is abnormal, determining that the receiving link 2 is in failure, and modifying the first message transmission mechanism by the processor. The modified first message transmission mechanism indicates: the processor receives the message sent by the optical module through the receiving link 1, the receiving link 3 and the receiving link 4.

The processor can send a notification message to the optical module through the IIC while modifying the first message transmission mechanism. The optical module modifies a second message transmission mechanism in the optical module based on the notification message, wherein the modified second message transmission mechanism indicates that: the optical module sends a message to the processor through the receiving link 1, the receiving link 3 and the receiving link 4.

In another embodiment of the present application, the plurality of links between the processor and the optical module include a plurality of transmission links, and the transmission links are used for transmitting messages received by the optical module. In this case, an embodiment of the present application further provides a message transmission method, as shown in fig. 5. In this method, step S101 may be subdivided into steps S1013 and S1014.

S1013, detecting whether a bit set as a preset value exists in an internal register of the optical module, where the internal register includes bits corresponding to each transmission link, the preset value is a value set by the optical module when detecting that an electrical signal of the transmission link is abnormal, and the preset value indicates a failure of the transmission link.

And S1014, if the value of the first bit in the internal register is a preset value, determining that the first transmission link corresponding to the first bit has a fault.

In this embodiment of the application, the number of the first bits may be one or more, and correspondingly, the number of the first transmission links may also be one or more.

The internal register of the optical module includes bits corresponding to each transmission link, that is, the bits in the internal register correspond to the transmission links one to one. The values of the bits in the internal register include preset values and other values. Wherein the preset value indicates that the transmission link is failed, and the other values indicate that the transmission link is normal. In the embodiment of the present application, the initial value of the bit in the internal register is other values.

The preset value and other values can be set according to actual requirements. For example, the preset value is 1, and the other values are 0; or the preset value is 0 and the other values are 1.

Based on the working principle described in the above section of fig. 2, that is: in the circuit, a receiving side of the link can sense whether the electrical signal of the link is abnormal or not. For the transmission link in the embodiment of the application, a receiver of the transmission link is the optical module, that is, the optical module can sense whether the transmission link is in failure.

The optical module can detect whether the abnormal sending link of the electric signal exists in the plurality of sending links in real time. If the electrical signals of one or more of the plurality of transmission links (for example, the first transmission link) are abnormal, the first transmission link is determined to be in failure. When the optical module detects that the electrical signal of the first transmission link is abnormal, namely when the first transmission link is determined to be in fault, the value of the bit corresponding to the first transmission link in the internal register is set to be a preset value.

The processor can detect in real time whether a bit set to a preset value exists in an internal register of the optical module. If the processor detects that a bit set to a preset value (for example, a value of a first bit) exists in an internal register of the optical module, it is determined that a transmission link (for example, a first transmission link) corresponding to the first bit has a fault.

If the processor detects that there is no bit set as the preset value in the internal register of the optical module, the processor may determine that there is no faulty transmission link, and then return to step S1013.

In the technical scheme provided by the embodiment of the application, the processor can conveniently and quickly determine the sending link with the fault through the internal register of the detection optical module. Therefore, as long as a group of normal sending links exist between the processor and the optical module, the messages between the processor and the optical module can be continuously transmitted, and the probability of network disconnection accidents caused by the failure of the sending links of the optical module is reduced.

Based on the message transmission method shown in fig. 5, an embodiment of the present application further provides a message transmission method, as shown in fig. 6. In this method, step S102 may be refined to step S1023.

S1023, a third message transmission mechanism in the processor is modified, so that the modified third message transmission mechanism instructs the processor to send a message to the optical module through other sending links, where the other sending links are sending links other than the first sending link.

In this embodiment, the third message transmission mechanism is a message transmission mechanism in the processor. The message transmission mechanism instructs the processor through which transmission links to transmit messages to the optical module.

The processor modifies the third message transmission mechanism upon detecting a failure of the first transmission link. And the modified third message transmission mechanism instructs the processor to send messages to the optical module through other sending links. That is, based on the modified third message transmission mechanism, the processor sends a message to the optical module through the normal sending link, so that the communication between the processor and the optical module is ensured.

Based on the message transmission method shown in fig. 5, an embodiment of the present application further provides a message transmission method, as shown in fig. 7. In this method, step S102 may be refined to step S1024.

And S1024, modifying a fourth message transmission mechanism in the optical module so that the modified fourth message transmission mechanism indicates the optical module to receive the messages sent by the processor through other sending links, wherein the other sending links are sending links except the first sending link.

In this embodiment, the fourth packet transmission mechanism is a packet transmission mechanism in the optical module. The message transmission mechanism indicates which processors the optical module receives the messages sent by the processors through the sending links of the processors.

The processor may modify a fourth message transmission mechanism in the optical module upon detecting the failure of the first transmission link. The modified fourth message transmission mechanism indicates the optical module to receive the message sent by the processor through other sending links. That is, based on the modified fourth message transmission mechanism, the optical module receives the message sent by the processor through the normal sending link, so as to ensure the communication between the processor and the optical module.

In this embodiment of the present application, the embodiments shown in fig. 6 and fig. 7 may be combined to modify the third message transmission mechanism and the fourth message transmission mechanism.

In another embodiment of the present application, when the optical module detects a failure of the first transmission link, the optical module may directly modify a fourth message transmission mechanism in the optical module, so that the modified fourth message transmission mechanism indicates the optical module to receive a message sent by the processor through another transmission link.

In the circuit, a receiving side of the link can sense whether the electrical signal of the link is abnormal or not. In the embodiment of the application, the optical module serves as a receiving party and can sense whether a sending link of the processor fails. And when the optical module senses that a plurality of sending links of the processor have a fault link, the fourth message transmission mechanism can be modified, so that the modified fourth message transmission mechanism indicates the optical module to receive the messages sent by the processor through other sending links. The time consumed from the detection of the first sending link failure to the completion of the modification of the fourth message transmission mechanism is effectively shortened, and the packet loss is further reduced.

In this embodiment, the fourth message transmission mechanism modification manner shown in fig. 7 and the fourth message transmission mechanism in the optical module directly modified by the optical module may be combined. Therefore, double guarantee is provided for modifying the fourth message transmission mechanism, the optical module can be further ensured to receive the message sent by the processor through a normal sending link, and the communication between the processor and the optical module is ensured.

In an embodiment of the present application, the processor may query an internal register of the optical module through the IIC, detect whether a bit set as a preset value exists in the internal register of the optical module, and further determine a failed transmission link. When detecting that the first transmission link is failed, the process may further send a notification message to the optical module through the IIC, where the notification message instructs the optical module to modify the fourth packet transmission mechanism. And the optical module modifies a fourth message transmission mechanism in the optical module based on the notification message, and the modified fourth message transmission mechanism instructs the optical module to send messages to the processor through other receiving links.

For example, the link structure between the optical module and the processor is shown in fig. 4. Fig. 4 takes a 100G high-speed optical module packaged by QSFP28 as an example, and the links between the optical module and the processor include 4 transmission links, namely transmission link 1, transmission link 2, transmission link 3, and transmission link 4. The preset value is 1.

And the processor queries an internal register of the optical module through the IIC to determine a fault sending link. The specific determination method is as follows: and detecting whether a bit set to be 1 exists in an internal register of the optical module in real time.

And the processor modifies the third message transmission mechanism when detecting that the transmission link 1 and the transmission link 2 are in failure. The modified third message transmission mechanism indicates: the processor sends a message to the optical module through the sending link 3 and the sending link 4.

The processor may send a notification message to the optical module through the IIC while modifying the third message transmission mechanism. The optical module modifies a fourth message transmission mechanism in the optical module based on the notification message, and the modified fourth message transmission mechanism indicates the optical module to receive the message sent by the processor through the sending link 3 and the sending link 4.

Based on the message transmission methods shown in fig. 5 to 7, the embodiment of the present application further provides a message transmission method. As shown in fig. 8, the method may further include step S1010 before the step of detecting whether a bit set to a preset value exists in the internal register of the optical module, that is, step S1013.

S1010, receiving an interrupt signal sent by the optical module, where the interrupt signal is a signal sent by the optical module when detecting that a faulty transmission link exists in the plurality of transmission links.

As described in the section of fig. 5, the optical module may perceive the failed transmit link. The optical module may send an interrupt signal to the processor when it senses a failure of the first transmission link. The processor then executes step S1013 in accordance with the interrupt signal.

The link structure between the optical module and the processor shown in fig. 4 is still taken as an example for description. The optical module can send an interrupt signal to the processor when sensing that the transmission link 1 and the transmission link 2 are failed. And the processor queries an internal register of the optical module through the IIC, determines a fault sending link and modifies a message transmission mechanism.

Corresponding to the above message transmission method, an embodiment of the present application provides a message transmission apparatus, as shown in fig. 9, which is applied to a processor, where multiple links exist between the processor and an optical module, and the apparatus includes:

a detecting unit 901, configured to detect whether a faulty link exists in multiple links;

a modifying unit 902, configured to modify a message transmission mechanism when a faulty link is detected in multiple links, so that the modified message transmission mechanism indicates that a message is transmitted between the processor and the optical module through other links, where the other links are links of the multiple links except the faulty link.

In this case, the detection unit 901 may be specifically configured to:

detecting whether a receiving link with abnormal electric signals exists in a plurality of receiving links;

and when the electrical signal abnormality of the first receiving link is detected, determining that the first receiving link is in failure.

In an embodiment of the present application, the modifying unit 902 may specifically be configured to:

In an embodiment of the present application, the plurality of links between the processor and the optical module include a plurality of transmission links, and the transmission links are used for transmitting a message to the optical module;

in this case, the detecting unit 901 may be specifically configured to:

detecting whether a bit set as a preset value exists in an internal register of the optical module, wherein the internal register comprises bits respectively corresponding to each transmitting link, the preset value is a value set by the optical module when the electrical signal of the transmitting link is detected to be abnormal, and the preset value indicates that the transmitting link fails;

and when the value of the first bit in the internal register is a preset value, determining that the first transmission link corresponding to the first bit has a fault.

In an embodiment of the present application, the modifying unit 902 may specifically be configured to:

In an embodiment of the present application, the detecting unit 901 may further be configured to:

receiving an interrupt signal sent by an optical module, wherein the interrupt signal is a signal sent by the optical module when a fault sending link exists in a plurality of sending links;

and detecting whether a bit set as a preset value exists in an internal register of the optical module or not according to the interrupt signal.

In the technical scheme provided by the embodiment of the application, the processor detects whether a fault link exists in a plurality of links between the processor and the optical module. And when a fault link exists, the processor modifies a message transmission mechanism, and based on the modified message transmission mechanism, the processor and the optical module use a normal link to transmit messages. Therefore, when the link of the optical module fails and waits for maintenance or replacement of the optical module, the optical module can still work, and the probability of network disconnection accidents caused by the failure of the link of the optical module is reduced.
