First, terms related to one or more embodiments of the present specification will be explained.

I2C protocol: (I2C: inter-Integrated Circuit BUS) integrated circuit bus, the I2C bus is a simple, bi-directional two-wire synchronous serial bus. Only two wires are required to transfer information between devices connected to the bus. The serial bus generally has two signal lines, one being a bidirectional data line SDA and the other being a clock line SCL. All serial data SDA connected to the I2C bus devices are connected to the SDA of the bus, and the clock line SCL of each device is connected to the SCL of the bus.

MCU: and a micro control unit (MCU, microcontroller Unit) in the optical module, also called a single-chip microcomputer (Single Chip Microcomputer) or a single-chip microcomputer.

An optical module: an optical module (optical module) is composed of an optoelectronic device, a functional circuit, an optical interface and the like, and the optoelectronic device comprises an emitting part and a receiving part. The optical module has the function that the transmitting end converts the electric signal into an optical signal, and the receiving end converts the optical signal into the electric signal after transmitting the optical signal through the optical fiber.

AOC: (AOC, active Optical Cable) is typically a design where a plurality of optical modules are interconnected by optical fibers, not supporting fiber optic pulling.

100G: g full-splice Gigabit,100G denotes a 100Gigabit/s transmission rate, and other numbers plus G are used to denote different transmission rates in the embodiments of the present specification.

Network equipment: the network device is a special hardware device for connecting various nodes such as servers, PCs, application terminals and the like to form an information communication network, and comprises an information network device, a communication network device, a network security device and the like. In one or more embodiments of the present disclosure, a network device connected to an optical module may be considered as a host side opposite to the optical module, for forwarding data.

In the present specification, an optical module monitoring method is provided. One or more embodiments of the present disclosure relate to an optical module monitoring apparatus, an optical module monitoring system, a computing device, a computer-readable storage medium, and a computer program, which are described in detail in the following embodiments.

The optical module applied in the current data center performs information interaction with the network equipment through an I2C channel formed by hardware low-speed pins, and the network equipment can obtain optical module manufacturer basic information, alarm information and the like written in an internal register of the optical module, so as to monitor the working state of the optical module in real time. When a bug occurs in a firmware program of an MCU device or the firmware program runs to an abnormal state in the running process, or when power supply fails to meet the standard in the running process of a module, and therefore the MCU does not work normally, the MCU (micro control unit) is hung up or an I2C controller is hung up in the optical module, network equipment cannot acquire information of the optical module through an I2C channel, or invalid information and messy code information are returned, and accordingly network equipment information judgment is affected.

Although the modules with different package types all define a certain number of hardware pins, each module has no pin capable of monitoring the MCU state, so when the MCU of the optical module is abnormal, the module can be reset only by external physical plug-in or reset pin of the network equipment hard-pull module. The module usually returns to normal after the plugging operation, and the module reset has a certain probability, but the phenomenon of MCU hanging is difficult to reproduce, which is very unfriendly for module developers to perform problem positioning and real-time monitoring of network equipment. Especially, the number of optical modules/AOCs used on line in a data center is millions, even if the probability of MCU faults is only one thousandth, thousands of modules cannot normally communicate with network equipment, and therefore on-line management of the optical modules/AOCs is very challenging.

The optical module MCU can also record states at regular time and store state information in the optical module register, or the optical module MCU only records abnormal states at regular time, the normal states are not recorded, the pressure on information storage is reduced, when the MCU breaks down, the module can be returned to a manufacturer after the MCU is in a fault, and the manufacturer performs problem analysis by reading the state information recorded in the register. However, the method cannot diagnose the MCU state of the optical module on line in real time, and has certain requirements on the memory of the register of the optical module.

In order to improve the effectiveness and usability of information interaction between the module and the network device, the embodiment of the description provides an optical module monitoring scheme, and by adding a low-speed pin for monitoring the MCU state of the optical module, the pin is multiplexed with the pins defined by the current standard, and the function use defined by the normal standard is not affected. When the optical module MCU breaks down, the state of the MCU can be monitored through the defined pins so as to grasp the fault phenomenon of the module MCU, so that the fault phenomenon is used for defining the root cause of the problem and guiding the next problem solution, and the problem solving efficiency and the system usability are greatly improved.

Specifically, the embodiment of the description provides an optical module monitoring method, which is applied to network equipment, and is used for acquiring attribute information stored in a target optical module, and writing preset enabling information into the target optical module under the condition that the attribute information is first attribute information for representing supporting monitoring, wherein the enabling information is used for enabling the target optical module to output the state information of the monitored target optical module through a target pin, receiving the state information monitored by the target optical module through the target pin, and obtaining the current state of the target optical module. By writing preset enabling information into the target optical module, flexible monitoring of the optical module is achieved, and the enabling information can enable the target optical module to output the monitored state information of the target optical module through the target pin, so that network equipment can capture the current state of the target optical module in real time, and accuracy of optical module monitoring is improved.

Referring to fig. 1, fig. 1 shows an application scenario schematic diagram of an optical module monitoring method provided in an embodiment of the present disclosure, where, as shown in fig. 1, an optical module monitoring system includes a network device and an optical module;

By applying the scheme of the embodiment of the specification, the attribute information stored in the target optical module is acquired; writing preset enabling information into the target optical module under the condition that the attribute information is first attribute information for representing supporting monitoring, wherein the enabling information is used for enabling the target optical module to output the state information of the monitored target optical module through a target pin; and receiving the state information monitored by the target optical module through the target pin to obtain the current state of the target optical module. By writing preset enabling information into the target optical module, flexible monitoring of the optical module is achieved, and the enabling information can enable the target optical module to output the monitored state information of the target optical module through the target pin, so that network equipment can capture the current state of the target optical module in real time, and accuracy of optical module monitoring is improved.

Referring to fig. 2, fig. 2 shows a flowchart of an optical module monitoring method according to an embodiment of the present disclosure, which is applied to a network device, and specifically includes the following steps:

step 202: and acquiring attribute information stored in the target optical module.

In one or more embodiments of the present disclosure, a network device may be connected to a plurality of optical modules, and in order to monitor a target optical module, it is first required to determine whether the target optical module to be monitored supports a monitoring function. In general, the optical module defines attribute information about whether to support monitoring when leaving the factory, and the network device determines whether to support monitoring by the target optical module by judging the attribute information stored in the target optical module.

Specifically, the target optical module refers to an optical module to be monitored in a plurality of optical modules connected to the network device, the attribute information refers to information stored in advance in the optical module and indicating whether the target optical module supports monitoring, for example, 0x00 indicates that the optical module does not support monitoring, 0x01 indicates that the optical module supports monitoring, of course, 0x00 also may indicate that the optical module supports monitoring, and 0x01 indicates that the optical module does not support monitoring. The attribute information stored in the optical module is specifically selected according to the actual situation, which is not limited in any way in the embodiment of the present specification.

When the target optical module needs to be monitored, the attribute information stored in the target optical module may be obtained through the output pin in the target optical module, and the manner of obtaining the attribute information stored in the target optical module is specifically selected according to the actual situation, which is not limited in the embodiment of the present disclosure.

In practical applications, after the attribute information stored in the target optical module is acquired, the acquired attribute information may be determined, that is, after the step of acquiring the attribute information stored in the target optical module, the method may further include the following steps:

judging whether the attribute information is first attribute information of which the characterization supports monitoring;

if not, determining that the target optical module does not support monitoring.

Specifically, the first attribute information characterizes information of the optical module supporting monitoring, and the target optical module supporting monitoring is determined under the condition that the attribute information stored in the target optical module is the same as the first attribute information; and determining that the target optical module does not support monitoring in the case that the attribute information stored in the target optical module is different from the first attribute information.

In practical applications, there are various ways of determining whether the attribute information is the first attribute information for supporting monitoring, and the embodiment of the present disclosure does not limit the manner in which the attribute information is specifically selected according to the practical situation.

In an optional implementation manner of the present disclosure, the obtained attribute information may be directly compared with first attribute information predefined by the target optical module, to determine whether the target optical module supports monitoring.

For example, assuming that the attribute information stored in the acquired target optical module is 0x01, the attribute information comparison table corresponding to the target optical module is shown in the following table 1, and the attribute information comparison table 1 is searched for 0x01, so as to determine that the target optical module supports monitoring.

Table 1 attribute information comparison table

Attribute information	Whether or not to support monitoring
		0x00	Unsupported monitoring
0x01	Support monitoring

It should be noted that, when it is determined that the target optical module supports monitoring, the target optical module may be further monitored, and when it is determined that the target optical module does not support monitoring, the network device stops operating, and the monitoring of the target optical module is ended.

By applying the scheme of the embodiment of the specification, after the attribute information stored in the target optical module is acquired, whether the attribute information is the first attribute information for representing supporting monitoring is judged, so that the monitoring of the target optical module is directly stopped under the condition that the target optical module does not support monitoring, the resource waste is avoided, and the cost is saved.

Step 204: and writing preset enabling information into the target optical module under the condition that the attribute information is first attribute information for representing supporting monitoring, wherein the enabling information is used for enabling the target optical module to output the state information of the monitored target optical module through a target pin.

In one or more embodiments of the present disclosure, after obtaining the attribute information stored in the target optical module, further, in the case that the attribute information is the first attribute information that characterizes supporting monitoring, preset enabling information may be written into the target optical module, so that the target optical module outputs the state information of the monitored target optical module through the target pin, so as to realize monitoring of the target optical module.

Specifically, the preset enabling information refers to information that enables the target optical module to output the state of the target optical module through the target pin, and the form of the enabling information is specifically selected according to the actual situation, which is not limited in any way in the embodiment of the present specification. The target pin is a preset pin capable of transmitting the state information of different optical modules MCU, and is a multiplexing pin and an output pin from the optical modules to the network equipment.

In practical application, after writing preset enabling information into the target optical module, whether the target optical module is enabled successfully can be judged, or whether the target optical module can output the state information of the monitored target optical module through the target pin can be understood, that is, after the step of writing preset enabling information into the target optical module, the method further comprises the following steps:

acquiring enabling information from a target optical module;

judging whether the target optical module is successfully enabled or not based on the enabling information;

the step of receiving the status information monitored by the target optical module through the target pin comprises the following steps:

and under the condition that the target optical module is successfully enabled, receiving the state information monitored by the target optical module through the target pin.

Specifically, in order to confirm whether the target optical module is enabled successfully, enabling information may be obtained from the target optical module, whether the target optical module is successful is determined based on the obtained enabling information, and in the case that the target optical module is enabled successfully, the state information of the monitored target optical module may be output through the target pin by the target optical module, and further, the network device may receive the state information monitored by the target optical module through the target pin.

By applying the scheme of the real-time example of the specification, after the preset enabling information is written into the target optical module, whether the target optical module is enabled successfully can be judged based on the enabling information in the target optical module, so that the accuracy of monitoring the target optical module is ensured.

It should be noted that, when the target optical module is judged to be not enabled successfully based on the enabling information, the method indicates that the target optical module is enabled abnormally, at this time, the network device may stop writing the enabling information into the target optical module, that is, after the step of judging whether the target optical module is enabled successfully based on the enabling information, the method may further include the following steps:

if not, stopping writing the enabling information into the target optical module, and determining that the enabling of the target optical module is abnormal.

Specifically, the abnormal enabling of the target optical module means that the target optical module cannot output the state information of the monitored target optical module through the target pin, and under the condition that the enabling of the target optical module is abnormal, the network equipment can stop writing the enabling information into the target optical module later so as to reduce the processing capacity of the network equipment and save resources.

In practical applications, there are various ways of determining whether the target optical module is enabled, and the method is specifically selected according to the actual situation, which is not limited in any way in the embodiments of the present disclosure.

In an optional embodiment of the present disclosure, the step of directly comparing the enabling information with preset enabling information to determine that the enabling information obtained from the target optical module is the same as the preset enabling information, that is, based on the enabling information, the step of determining whether the target optical module is enabled successfully may include the following steps:

judging whether the enabling information is the same as preset enabling information or not;

if the target optical modules are the same, the target optical modules are determined to be enabled successfully.

Specifically, the network device writes preset enabling information into the target optical module, and the target optical module receives the enabling information, and at this time, if it is uncertain whether the information received by the target optical module is correct, that is, if the target optical module is enabled successfully, the written enabling information can be obtained from the target optical module, and whether the obtained enabling information is identical to the preset enabling information is determined.

For example, the enabling information is obtained from the target optical module and is 0x01, the preset enabling information is 0x01, the enabling information is compared with the enabling information which is 0x01 and is 0x01, the obtained enabling information is determined to be identical with the preset enabling information, and the target optical module is enabled successfully.

By applying the scheme of the embodiment of the specification, whether the enabling information is the same as the preset enabling information is judged, and the writing of the enabling information to the target optical module can be stopped under the condition that the enabling information is different, so that the processing capacity of the network equipment is reduced, and resources are saved.

In another optional implementation manner of the present disclosure, after the enabling information in the target optical module is acquired, a check code of the enabling information is generated, and the generated check code is compared with a preset check code to determine whether the target optical module is enabled successfully.

It should be noted that, the step of generating the check code may be performed by the target optical module or may be performed by the network device, and specifically, the step is selected according to the actual situation, which is not limited in any way in the embodiment of the present disclosure.

Further, after the target optical module is successfully enabled, the network device can write the enabling information for closing the optical module monitoring function into the target optical module under the condition that the monitoring of the target optical module is not needed, so that the target optical module stops outputting the state information of the monitored target optical module through the target pin.

Step 206: and receiving the state information monitored by the target optical module through the target pin to obtain the current state of the target optical module.

According to the scheme of one or more embodiments of the present disclosure, attribute information stored in a target optical module is obtained, and after preset enabling information is written into the target optical module under the condition that the attribute information is first attribute information for representing supporting monitoring, further, state information monitored by the target optical module can be received through a target pin, so that a current state of the target optical module is obtained.

Specifically, the state information may be understood as pulse information, and the MCU state carrying the target optical module includes a normal state, an abnormal state 1, an abnormal state 2, or an unknown abnormality, which is specifically generated according to an actual situation, and the embodiment of the present disclosure is not limited in any way.

Exemplarily, assuming that the received frame information is 10100001, it indicates that the target light module MCU is in a normal operation state; the received frame information is 10100010, which indicates that the MCU of the target optical module has abnormal power supply; the received frame information is 10100011 indicating that the target light module MCU software is operating abnormally, etc.

In practical application, after the pulse information sent by the optical module MCU is monitored, the verification information carried in the state information may be verified by using a preset verification rule to obtain the current state of the target optical module, that is, the step of receiving, by the target pin, the state information monitored by the target optical module to obtain the current state of the target optical module may include the following steps:

and checking the verification information carried in the state information by using a preset verification rule to obtain the current state of the target optical module.

Specifically, the status information received through the target pin may include a frame header, a frame type, frame information and a check bit, and whether the status information received through the target pin is in error in the transmission process may be determined through the check bit, and the check method of the check bit may specifically be generated according to an actual situation, which is not limited in any way in the embodiment of the present specification.

The information of the whole received frame is 16 bits, namely a frame header (4 bits), a frame type (2 bits), frame information (8 bits) and a check bit (2 bits), and the value added by the 14 bits of the frame header, the frame type and the frame information can be checked to judge that the received information accords with a preset rule, so that the current state of the target optical module is further obtained.

By applying the scheme of the embodiment of the specification, the current state of the target optical module is obtained by utilizing the verification information carried in the preset verification rule verification state information, so that whether the state information is wrong in the transmission process can be determined, the error decoding of the received clutter information is avoided, and the monitoring accuracy of the target optical module is further improved.

Referring to fig. 3, fig. 3 shows a flowchart of another optical module monitoring method according to an embodiment of the present disclosure, which is applied to a target optical module, and specifically includes the following steps:

step 302: and receiving enabling information written in by the network equipment, wherein the enabling information is attribute information stored in the target optical module by the network equipment, and writing the enabling information into the target optical module under the condition that the attribute information is first attribute information representing that monitoring is supported.

Step 304: and outputting the monitored state information of the target optical module through the target pin, so that the network equipment receives the state information through the target pin and obtains the current state of the target optical module.

Specifically, the mode of outputting the monitored state information of the target optical module through the target pin is various, and is specifically selected according to the actual situation, which is not limited in any way in the embodiment of the present specification.

In an optional embodiment of the present disclosure, the target optical module may output the monitored state information of the target optical module through the target pin in real time, so that the network device receives the state information through the target pin, and obtains the current state of the target optical module.

In another optional implementation manner of the present disclosure, the target optical module may output the monitored state information of the target optical module through the target pin at intervals of a preset period of time, so that the network device receives the state information through the target pin, and obtains the current state of the target optical module.

By applying the scheme of the embodiment of the specification, the enabling information written in by the network equipment is received, wherein the enabling information is the state information of the monitored target optical module which is written in the target optical module under the condition that the attribute information is the first attribute information representing the support of monitoring by acquiring the attribute information stored in the target optical module, so that the network equipment receives the state information through the target pin to obtain the current state of the target optical module, the current state of the target optical module is accurately grasped, and the accuracy of monitoring the optical module is improved.

In practical applications, the method may define the target pins in the target optical module in advance, that is, before the step of outputting the monitored state information of the target optical module through the target pins, the method may further include the following steps:

determining a target pin in the target optical module, wherein the target pin is any output type pin in the target optical module;

the target pin is redefined so that the target pin transmits status information of the target optical module.

It should be noted that, under the condition that the MCU fault or abnormality occurs in the optical module, due to the possible failure condition of the SDA pin or the SCL pin, no channel is available for obtaining the fault information or the abnormality information, so that the source of the fault or the abnormality cannot be judged. Therefore, one low-speed pin (i.e. output pin) in the target optical module can be multiplexed, the low-speed pin is used as a target pin, namely, the target pin is redefined, a function is added on the standard definition of the target pin, and the function can report the MCU state information of the target optical module, so that the network equipment knows the state of the optical module MCU, the abnormal problem is determined, a solution is provided pertinently, the effectiveness of data interaction between the optical module and the network equipment is further improved, and the usability of the whole system is improved to a certain extent.

Specifically, a module firmware setting is required for the optical module before adding a function to the target pin. The specific setting process may include the following three parts, the first part: redefining a module target pin to realize a module pin multiplexing function, and transmitting different MCU state information of the optical module; a second part: firmware definition, namely adding defined software program into the MCU of the optical module to change the multiplexing function of the target pin; third section: the network equipment firmware definition is a software program in the network equipment connected optical module hardware target pin equipment and is used for monitoring information sent by the optical module through the target pin.

Illustratively, in the standard definition state, if the module does not have any anomalies, the optical module target pin output signal is high; if the module has an alarm abnormality, the optical module target pin out signal is low and will remain low. Pin multiplexing mode: two bytes can be added in a read-only memory (useep) of the module to realize support confirmation and enabling switching of the MCU monitoring function, when the module register completes switching of enabling the MCU monitoring function, the multiplexed target pin does not realize the standard defined interrupt signal marking function any more, and becomes the MCU monitoring function, and the specific switching is completed by the module MCU firmware.

By applying the scheme of the embodiment of the specification, when the network equipment cannot normally communicate with the optical module, after the problem of the network equipment is eliminated, the network equipment judges whether the MCU of the module works normally or not by analyzing the received MCU state of the optical module, so that the MCU state of the module can be monitored on line in real time, and whether the current problem is related to MCU hanging is confirmed, if the current problem is the MCU problem, the network equipment can complete MCU fault information grabbing and guide the operation of solving the problem in the next step; if the problem of MCU is not solved, the problem of physical contact between the golden finger of the module and the connector is considered, and the physical plug is directly carried out, so that the invalid operation is reduced.

The optical module monitoring method provided in the present specification is further described below with reference to fig. 4. Fig. 4 shows a process flow chart of an optical module monitoring method according to an embodiment of the present disclosure, which specifically includes the following steps:

network equipment: when the optical module is monitored, the network equipment is powered on, and the optical module is inserted at the same time, so that the optical module is on line. The device connected with the hardware target pin of the module is provided with a program for judging whether the monitoring module has MCU monitoring capability and enabling MCU monitoring, and mainly reads and writes the content of the module register respectively, and can be understood as reading attribute information and writing enabling information.

Specifically, after the optical module is monitored by the port of the network equipment, attribute information is automatically read to enable the network equipment to judge whether the optical module supports monitoring, if not, the optical module is read to confirm that the optical module does not support monitoring, the current standard definition function of the multiplexing target pin is maintained, the network equipment does not perform any operation, and the monitoring of the optical module is ended; if the network device confirms that the optical module supports monitoring, the network device actively writes preset enabling information into the optical module, and the network device can also be understood as enabling the monitoring function of the optical module. Under the condition of failure of enabling, the network equipment stops writing enabling information into the optical module, reports enabling abnormality and finishes monitoring the optical module; and under the condition that the enabling is successful, receiving the state information monitored by the optical module through the target pin.

It should be noted that, when the network device cannot receive the status information, reporting the monitoring abnormality, and ending the monitoring of the optical module; and under the condition that the state information is received, automatically analyzing the state information, thereby obtaining the current state of the optical module, namely analyzing and confirming the state.

A target optical module: after the module is switched to enable the MCU monitoring function, the optical module MCU automatically sends out a section of state information in a custom format to the network equipment through the multiplexed target pin at intervals of a fixed time, and the state information is used for representing the current MCU state.

By applying the scheme of the embodiment of the specification, the real-time monitoring of the MCU state of the optical module is realized on the premise of not influencing the existing hardware design scheme by multiplexing the low-speed pins on the basis of the standard definition module, the efficiency of positioning the problem is greatly improved, and the current situations of poor fault reproduction and catching phenomenon are solved. And adding a register identification bit for supporting the MCU monitoring function or not and a register address bit for switching the MCU monitoring function on the basis of the standard definition module, and automatically rewriting a module custom register by network equipment if the network equipment monitors that the module has the MCU monitoring function after the module is on line, so as to realize the MCU state monitoring of the module. If the network equipment monitors that the module does not have the MCU monitoring function, no operation is performed. Meanwhile, if the standard network equipment does not have the MCU state monitoring function of the monitoring module, the MCU state monitoring of the module is not enabled, and the application of the module on the standard network equipment is prevented from being influenced. The ability of monitoring and enabling the module MCU monitoring function is added to the standard network equipment, the network equipment realizes whether the module supports the confirmation of the MCU monitoring function, the enabling and disabling of the MCU monitoring and the analysis of the state information sent by the module MCU through the pre-written program, and when the monitoring function is enabled, whether the module MCU problem is clear or not can be determined, the following problem solution is guided, and the problem solving efficiency and the system usability are greatly improved.
