Detailed Description

For the purpose of promoting a better understanding of the objects, aspects and advantages of the present disclosure, reference is made to the following detailed description taken in conjunction with the accompanying drawings.

It is to be noted that technical terms or scientific terms used in the embodiments of the present disclosure should have a general meaning as understood by those having ordinary skill in the art to which the present disclosure belongs, unless otherwise defined. The use of "first," "second," and similar terms in the embodiments of the disclosure is not intended to indicate any order, quantity, or importance, but rather to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

In order to describe the technical parameters of the optical module and other information, a common manufacturer needs to store the parameters in an EEPROM built in the optical module. In order to unify the content standards in EEPROM, the global network storage industry association defines a specific format SFP, QSFP/QSFP +/QSFP-DD, XFP (SFF-8477). According to these standards, the capacity of an EEPROM is up to several kilobytes. With the increase of the number of optical modules in the system, when the number of the optical modules reaches more than hundreds, the defect that the reading speed of the optical modules is slow appears. Taking the size of the EEPROM of most optical module modules at present in 1024 bytes 1K as an example, the I2C bus with the frequency of 100K is used for reading, and it takes approximately 1 minute at least to finish reading all data. This is not usually allowed in practical application scenarios, such as fast restart scenarios, due to the long read time.

According to the existing standard, the optical module generally adopts an I2C bus to read, and uses a CPU to operate the content in the EEPROM in a synchronous or asynchronous mode. Some advanced devices are configured with multiple I2C buses, so that the optical module can be operated by multiple I2C buses simultaneously to speed up the operation of the optical module. However, the present disclosure recognizes that the increase of the time and speed by adding a plurality of I2C buses or increasing the speed of I2C buses, etc., not only increases the design cost of hardware, but also the cost is increased sharply especially when the number of optical modules increases dramatically, for example, the number of optical modules increases to 256 or more; and increasing the speed of I2C increases the reading instability of the optical module. In addition, the EEPROM of the optical module has its own timing, and only by simply increasing the speed of I2C, it is possible to reduce the data transmission time, and it is not possible to reduce the data writing and reading time. Therefore, it is not desirable to simply increase the reading speed of the optical module by increasing hardware, and a technology for increasing the reading speed of the optical module without increasing the cost is urgently needed.

In view of this, the embodiments of the present disclosure provide a communication method, apparatus, device, and medium for quickly reading and writing optical module parameter information, which improve the speed of reading the optical module parameter information on the premise that hardware is not changed. Referring to fig. 1, fig. 1 shows a schematic diagram of a communication apparatus for quickly reading and writing parameter information of an optical module according to an embodiment of the present disclosure. Referring to fig. 1, a communication apparatus 100 includes:

at least one optical module 110 for receiving and transmitting optical signals and implementing conversion between the optical signals and electrical signals;

and a communication module 120 connected to at least one of the optical modules 110, and configured to implement transmission of the electrical signal with the optical module 110.

In some embodiments, the light module 110 and the communication module 120 communicate by way of a bus. Further, data transfer may be accomplished via the I2C bus.

In some embodiments, the light modules 110 store their own identification information. Further, the identification information is stored in a memory (EEPROM) of the optical module 110. In some embodiments, the memory of the light module 110 may also store its own parameter information. The parameter information may refer to information required by the optical module 110 to implement data transmission in the physical layer, such as a transmission rate, a transmission distance, a center wavelength, an optical fiber type, an optical port type, an operating temperature range, a maximum power consumption, and the like.

In some embodiments, the communication module 120 stores a light module database locally. The optical module database may include mapping between identification information of an optical module and parameter information of the optical module, and the parameter information corresponding to the optical module may be found according to the identification information of one optical module.

In some embodiments, the communications apparatus 100 may also communicate with the remote device 130 over a network. Further, the remote device 130 may also store the light module database. In this way, the communication apparatus 100 may obtain the parameter information of the optical module 110 from a local optical module database or an optical module database of the remote device 130, or store the parameter information corresponding to the optical module in the local optical module database or the optical module database of the remote device 130. In some embodiments, the communication apparatus 100 and the remote device 130 communicate with each other in a wired or wireless manner. Therefore, by using the optical module database built at the far end, the sharing of the optical module data among different devices can be realized, and the system overhead for building the optical module database for the first time is further reduced.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a communication method for quickly reading and writing parameter information of an optical module according to an embodiment of the present disclosure. As shown in fig. 2, a communication method 200 for quickly reading and writing parameter information of an optical module may include:

step S210, receiving a reading instruction, wherein the reading instruction is used for acquiring identification information of an optical module;

step S220, in response to the reading instruction, acquiring identification information of the optical module from the optical module;

step S230, acquiring parameter information corresponding to the optical module from an optical module database based on the identification information; and the optical module database is stored in local equipment or remote equipment.

The parameter information of the optical module is stored in a local or remote optical module database, only the identification information of the optical module is read from the optical module, and then the parameter information of the optical module corresponding to the identification information is read from the optical module database according to the identification information, so that the speed of reading the parameter information of the optical module is increased on the premise of keeping hardware unchanged, and the restarting speed of equipment is increased. Compared with a mode of reading parameter information from the optical module in the traditional method, the method does not need to read the information from the optical module every time, reduces the limitation caused by the slow reading speed of the I2C bus, improves the reading speed of the optical module, and avoids the problem of cost increase caused by increasing hardware to speed up. It should be appreciated that methods according to embodiments of the present disclosure may be deployed in a network device, such as a device at a network node.

According to an embodiment of the present disclosure, before step S210, the method 200 may further include:

judging whether the optical module has a writable area or not;

and if the optical module has a writable area, generating the identification information based on the writable area.

In some embodiments, generating the identification information of the light module based on the ID information may further include:

and if the optical module does not have the writable area, newly generating the ID information and the manufacturer of the optical module into the identification information.

In some embodiments, the ID information may be a Serial Number (SN) of the optical module.

The identification information of the optical module is information that can uniquely identify the optical module. The optical module may directly employ ID information as identification information, e.g. a serial number. However, since there are many manufacturers of optical modules, there may be a problem that ID information is duplicated, and at this time, identification information capable of uniquely identifying an optical module may be regenerated for the optical module. If the optical module has a writable area, a global UUID (Universal Unique Identifier) can be defined as Unique identification information by using the writable area of the optical module EEPROM; if the light module does not have a writable area, an identification information can be regenerated based on the ID information and the vendor information, for example: the identification information may be a manufacturer code + ID information, for example 01123456789, 01 may be a manufacturer code indicating manufacturer a (the manufacturer code may also be abbreviated by using a manufacturer name letter, and the like, without limitation), and 123456789 is an SN of the optical module. It should be understood that the above description is only for illustration and not intended to limit the identification information, and the identification information may also take other forms according to practical situations, and is not limited herein.

According to an embodiment of the present disclosure, before step S210, the method 200 may further include: and establishing the optical module database based on the parameter information and the identification information of the optical module.

Step S330, generating the identification information of the module, and reading the identification information again as key information; for example, it may be continuously determined whether the optical module has a writable area; if the optical module has a writable area, defining a global unique identification information based on the writable area; if the optical module does not have the writable area, newly generating identification information by the ID information and a manufacturer; step S340 is performed.

Step S340, determining whether parameter information of the optical module has been recorded in an optical module database (which may be local or remote device); for example, it may be determined whether key information (or identification information) of the optical module exists in the optical module database;

if the parameter information of the optical module is already recorded in the optical module database, executing step S350; if the parameter information of the optical module is not recorded in the optical module database, step S360 is executed.

Step S370, writing the identification information of the optical module as a key and the parameter information currently stored in the EEPROM of the optical module as a value into the optical module database.

In practical applications, the parameter information stored in the optical module EEPROM may include different read-write characteristics, some data is readable, the part of data is generally not changed and changed, and some data is readable and writable, and the part of data may be changed. After the optical module database is established, when the parameter information of the optical module with changed parameters needs to be updated, only the readable and writable part can be updated, and all the parameter information of the optical module does not need to be read again, so that the establishment of the optical module database can be accelerated, and the establishment efficiency of the optical module database is improved.

In some embodiments, referring to fig. 4, fig. 4 shows a schematic flow diagram of building a light module database according to an embodiment of the present disclosure. As shown in fig. 4, establishing the optical module database based on the parameter information of the optical module and the identification information may further include:

Step S420, judging whether the key value needs to be read again; for example, it may be determined whether there is duplicate of the ID information;

if the key information needs to be read again, performing step S430;

if the key information does not need to be read again, taking the ID information as the key information of the optical module; step S440 is performed.

Step S430, generating the identification information of the module, and reading the identification information again as key information; for example, it may be continuously determined whether the optical module has a writable area; if the optical module has a writable area, defining a global unique identification information based on the writable area; if the optical module does not have the writable area, newly generating identification information by the ID information and a manufacturer; step S440 is performed.

Step S440, determining whether parameter information of the optical module has been recorded in an optical module database (which may be local or remote device); for example, it may be determined whether key information (or identification information) of the optical module exists in the optical module database;

if the parameter information of the optical module is already recorded in the optical module database, executing step S450; if the parameter information of the optical module is not recorded in the optical module database, step S480 is executed.

Step S480, writing all current parameter information in the optical module EEPROM into the optical module database. For example, at least some of the steps shown in FIG. 3 may be employed.

According to the embodiment of the present disclosure, in step S210, a reading instruction is received, where the reading instruction is used to acquire parameter information of an optical module.

The reading instruction may be an instruction sent by a user through an input device, for example, a user sends out through a program instruction; or the instruction may be an instruction automatically issued after the network device is powered on, for example, the parameter information of the optical module is automatically read after the network device is restarted. As shown in fig. 1, the communication device 100 may generate a reading instruction after powering on, and acquire parameter information of the optical module 110 via the communication module 120.

According to the embodiment of the present disclosure, in step S220, in response to the reading instruction, the identification information of the optical module is acquired from the optical module.

As shown in fig. 1, the communication module 120 may obtain identification information of the optical module 110 from the optical module in response to the read instruction. After receiving the reading instruction, the communication module 120 may send an acquisition instruction to the optical module 110 through the I2C bus to acquire the identification information, and after receiving the acquisition instruction, the optical module 110 returns the identification information of the optical module 110 to the communication module 120 through the I2C bus.

As shown in fig. 1, based on an optical module database established in a local or remote device, parameter information of the optical module 110 may be found according to the identification information of the optical module 110, and read. In this way, in the data transmission between the communication module 120 and the optical module 110, a large amount of parameter information is changed into a small amount of identification information, and then the corresponding parameter information is read from the optical module database, so that the reading speed of the parameter information of the optical module is increased, and the problem of slow reading speed of the content of the EEPROM in a large amount of optical modules is solved.

Wherein the integrity indicator may comprise a data fingerprint identifying whether the data is complete. Due to the limited space of the optical module EEPROM and the influence of the writing or reading speed, the integrity flag is generally generated by using an algorithm with a small number of bytes.

In some embodiments, the integrity indicator may be generated based on CRC32, MD5, SM2, or SHA algorithms.

Step S540, determining whether parameter information of the optical module has been recorded in an optical module database (which may be local or remote device); for example, it may be determined whether key information (or identification information) of the optical module exists in the optical module database;

if the parameter information of the optical module has been recorded in the optical module database, step S550 is executed; if the parameter information of the optical module is not recorded in the optical module database, step S560 is executed.

Step S550, reading the parameter information of the optical module from the optical module database, and judging the integrity of the read parameter information; for example, the parameter information a read from the optical module database for the optical module and the parameter information B currently stored in the optical module EEPROM may be compared, if the parameter information a is consistent with the parameter information B, it indicates that the read parameter information is complete, otherwise, it indicates that the read parameter information is incomplete;

if the read parameter information is not complete, performing step S570; if the read parameter information is complete, step S580 is performed.

Step S560, storing the parameter information of the optical module in an optical module database, for example, at least some of the steps described in fig. 3 may be adopted; step S540 is performed.

Step S570, updating the parameter information corresponding to the optical module in the optical module database based on the parameter information currently stored in the optical module EEPROM; for example, parameter information a of the optical module in the optical module database may be replaced or updated with parameter information B currently stored in the optical module EEPROM; wherein, when updating, the readable and writable data can be updated, and at least part of the steps described in fig. 4 can be adopted; step S580 is performed.

Step S580, returning the parameter information of the optical module read from the current optical module database; for example, the parameter information read in step S550 may be used, or the parameter information read in the updated optical module database in step S570 may be used.

According to an embodiment of the present disclosure, the method 200 may further include:

acquiring first parameter information from the optical module, and acquiring second parameter information corresponding to the optical module from the optical module database;

judging whether the first parameter information and the second parameter information have difference or not;

if the first parameter information and the second parameter information are different, judging the integrity of the second parameter information;

updating the first parameter information based on the second parameter information if the second parameter information is complete.

In some embodiments, updating the first parameter information based on the second parameter information may include:

comparing the second parameter information with the first parameter information to obtain difference information;

and writing the difference information into the optical module to update the first parameter information.

The difference information may refer to a place where the second parameter information is different from the first parameter information, that is, the first parameter information is updated based on the second parameter information.

When the parameter information in the optical module database is complete and the parameter information in the optical module memory EEPROM is incomplete, the parameter information in the optical module memory can be supplemented based on the parameter information in the optical module database to ensure the integrity of the parameter information in the optical module memory EEPROM. When data are written into the memory EEPROM of the optical module, differentiated data are written into the data, not all the data, so that the frequency of writing operation of the memory EEPROM of the optical module is reduced to the maximum extent.

In some embodiments, if there is no difference between the first parameter information and the second parameter information, or the second parameter information is incomplete, then ending.

In some embodiments, referring to fig. 6, fig. 6 shows a schematic example of a communication method for fast writing light module parameter information according to an embodiment of the present disclosure. As shown in fig. 6, a communication method 600 for fast writing parameter information of a light module may include:

step S610, acquiring first parameter information in an EEPROM (electrically erasable programmable read-only memory) of an optical module and second parameter information of the optical module in an optical module database; step S620 is performed.

Step S620, comparing the first parameter information with the second parameter information; step S630 is performed.

Step S630, determining whether the first parameter information and the second parameter information are different, if yes, executing step S640; if there is no difference, it ends.

Step S640, determining whether the second parameter information is complete, for example, updating the database, and calculating the integrity of the second parameter information; if the second parameter information is complete, step S650 is performed, otherwise, it ends.

In step S650, the first parameter information is updated based on the difference information between the second parameter information and the first parameter information, for example, the difference information is written into the optical module memory EEPROM.
