Wherein the at least one first application program interface comprises the at least one second application program interface. The at least one first application program interface may be predefined according to different processing operations for different controlled boards. The at least one second application program interface may be identical to the at least one first application program interface and may be selected from the at least one first application program interface for determination in accordance with the processing operation required by the controlled board itself.

When the communication device is an optical transmission device, as shown in fig. 2b, an embodiment of the present application further provides an optical communication method, where the technical solution of the present embodiment is executed by a main control board, and may include the following steps:

21: and determining a target application program interface corresponding to the target processing operation from at least one pre-configured first application program interface aiming at the target processing operation of the optical processing board.

The optical processing board can be any optical processing board or a designated optical processing board or an optical processing board inserted into a specific hardware interface, and the like.

22: and sending the interface related information of the target application program interface and the parameter information of the target processing operation to the optical processing board.

After the optical processing board obtains the interface related information and the parameter information, the target application program interface may be called from at least one second application program interface that is pre-configured to perform the target processing operation based on the interface related information and the parameter information.

The detailed operation descriptions of steps 21 to 22 can be seen in steps 11 to 12 in the embodiment shown in fig. 2a, and the difference from the embodiment shown in fig. 2a is that in an optical communication scenario, the controlled board is specifically an optical processing board, and other same or similar operations are not repeated here.

In some embodiments, after the controlled board calls the target application program interface to execute the target processing operation, the execution result may be fed back to the main control board, and therefore, the method may further include:

In addition, in order to realize and unify the information transmission mode, in some embodiments, the interface related information of the target application program interface and the parameter information of the target processing operation are sent to the controlled board;

taking the parameter information of the target processing operation as an input parameter of a target application program interface;

carrying out Serialization (Serialization) processing on a target application program interface to obtain first Serialization data;

and sending the first serialized data to a controlled board, and obtaining the interface related information and the parameter information by the controlled board from the deserialization data.

Through serialization processing, the conversion character form of the target application program interface can be transmitted to the controlled board, and the controlled board can obtain the target application program through anti-sequence processing, so that interface related information, parameter information and the like can be obtained.

The serialization is a mode of converting an object or a function into a form capable of being stored or transmitted to obtain serialized data, and the object or the function can be reconstructed by performing anti-sequence processing on the serialized data. Therefore, the target application program interface can be converted into other forms to be transmitted to the controlled board by adopting a serialization mode, and the controlled board can obtain the target application program interface only by performing anti-sequence processing.

In addition, in order to standardize and unify the information transmission mode, improve the security of information transmission, and the like, in some embodiments, the sending the interface related information of the target application program interface and the parameter information of the target processing operation to the controlled board includes:

encoding the parameter information of the target processing operation according to a preset encoding rule;

and sending the interface related information and the coded parameter information to the controlled board, and decoding the coded parameter information by the controlled board according to a preset coding rule to obtain the parameter information.

The main control board and the controlled board can encode and decode the parameter information according to the predetermined encoding rule by appointing the uniform predetermined encoding rule, thereby restricting the information transmission form and realizing the information transmission.

Wherein, the predetermined encoding rule may be a parameter format that specifies input parameters of different application program interfaces, since the parameter information of the target processing operation is used as the input parameter of the target application program interface. The parameter information of the target processing operation can be encoded according to a parameter format corresponding to the target application program interface in a preset encoding rule. The controlled board can decode according to the parameter format corresponding to the target application program interface to obtain the parameter information.

Optionally, the sending of the interface related information and the parameter information after encoding to the controlled board may be: taking the encoded parameter information as an input parameter of a target application program interface; carrying out serialization processing on a target application program interface to obtain first serialized data; and sending the first serialized data to a controlled board, and obtaining the interface related information and the parameter information by the controlled board from the deserialization data.

As can be seen from the foregoing description, the controlled board may feed back the execution result to the main control board, optionally, the execution result may be returned to the main control board as an output parameter of the target application program interface, and the controlled board may specifically use the execution result as an output parameter of the target application program interface; and performing deserialization processing on the target application program interface to obtain second serialized data, and feeding the second serialized data back to the main control board. Therefore, in some embodiments, obtaining the execution result of the target processing operation sent by the controlled board may include: and acquiring second serialized data sent by the controlled board, and performing deserialization on the second serialized data to obtain an execution result.

Optionally, the controlled board may also encode the execution result according to a predetermined encoding rule and feed back the encoded execution result to the main control board. The predetermined encoding rule may specify parameter formats corresponding to output parameters of different application program interfaces, and therefore, the execution result may be encoded according to the parameter format corresponding to the output parameter of the target application program interface in the predetermined encoding rule.

After the controlled board encodes the execution result, the encoded execution result may be specifically used as an output parameter of the target application program interface, and then the target application program interface is subjected to serialization processing. Therefore, the acquiring, by the master board, the execution result of the target processing operation sent by the slave board may include:

acquiring second serialized data sent by the controlled board; the second serialization data is obtained by performing serialization processing on a target program interface after the execution result of the target processing operation of the controlled board is used as the output parameter of the target application program interface; deserializing the second serialized data to obtain a return parameter;

and decoding the returned parameters according to a preset coding rule to obtain parameter information.

The master control board and the controlled board can establish a specific communication channel according to a convention to transmit information. Thus, in some embodiments, the method may further comprise:

establishing a communication channel with a controlled board;

sending the interface related information of the target application program interface and the parameter information of the target processing operation to the controlled board comprises:

and sending the interface related information and the parameter information to the controlled board through a communication channel.

The communication channel may be established in a pre-specified manner to standardize and unify communication channels between different circuit boards.

The communication channel may be, for example, a communication channel established based on TCP/UDP (Transmission Control Protocol/User data Protocol).

In addition, as another alternative, the master board may establish a communication channel with the slave board through message middleware.

The master control board and the controlled board can be respectively configured with communication components of the message middleware, so that information transmission is realized through the message middleware. The sending of the interface related information and the parameter information to the controlled board through the communication channel may be: and issuing the interface related information and the parameter information to the message middleware so that the controlled board can obtain the interface related information and the parameter information from the message middleware.

The specific communication mode of the message middleware is the same as the conventional mode, for example, the related information may be sent to the message middleware, stored in a queue by the message middleware, and forwarded to the controlled board at a suitable time, which is not specifically limited in the present application.

After the communication channel is established between the master control board and the controlled board, the master control board may uniquely identify the controlled board according to slot position information of a hardware interface where the controlled board is located, or a device identifier of the controlled board, or the like.

As can be seen from the foregoing description, the controlled board can be inserted into a hardware interface of the communication device, and may specifically refer to a slot provided by the main control board, by adopting the technical solution of the embodiment of the present application, the main control board and the controlled board are decoupled, and are not limited to a system of the same manufacturer, plug and play of the controlled board can be realized,

in order to facilitate understanding of the technical solution of the present application, the following explains the corresponding execution steps by respectively taking the target processing operation as an identification operation, a configuration operation, and a resource processing operation.

When the target processing operation is the identification operation, the main control board determines, according to the target processing operation for the controlled board, that the target application program interface may be: under the condition that any hardware interface is inserted into the controlled board, reading the equipment information of the controlled board from the hardware interface; and determining an identification operation for the controlled board, and determining an identification interface corresponding to the identification operation from at least one preconfigured application program interface;

sending the interface related information of the target application program interface and the parameter information of the target processing operation to the controlled board may be: the interface related information of the identification interface and the parameter information of the identification operation are sent to the controlled board, so that the controlled board can call the identification interface from at least one second application program interface which is pre-configured to execute the identification operation based on the interface related information and the parameter information, so as to obtain the system type of the controlled board, and the system type is fed back to the main control board as an execution result;

the main control board can determine whether the hardware interface is inserted into the controlled board by detecting the in-place information of the hardware interface after the controlled board is inserted into the hardware interface and powered on.

By reading the hardware interface, the hardware information of the controlled board, such as the device information, including the specified requirements of the device manufacturer on the size, performance, etc. such as the device model, the device specification, etc., can be obtained. Information read through a hardware interface is limited, and therefore, an application program interface for performing an identification operation may be predefined in the embodiments of the present application, and is named as an identification interface for convenience of description.

The controlled board calls the corresponding identification interface to execute identification operation, and the system type of the controlled board can be obtained; the system type may specifically refer to a system type of an operating system configured by the controlled board, and may include information such as a system name and a system version, and may further obtain an interface type supported by the controlled board, a supported processing function, and the like.

After the master control board obtains the device information, the system type and other information of the controlled board, the configuration operation and the like can be performed on the controlled board according to the information.

When the target processing operation is a configuration operation, the main control board determines, according to the target processing operation for the controlled board, that the target application program interface may be: determining a configuration operation aiming at the controlled board, and determining a configuration interface corresponding to the configuration operation from at least one preconfigured application program interface;

the sending of the interface related information of the target application program interface and the parameter information of the target processing operation to the controlled board may be: sending the interface related information of the configuration interface and the parameter information of the configuration operation to the controlled board, so that the controlled board calls the configuration interface to execute the corresponding configuration operation from at least one second application program interface which is pre-configured based on the interface related information and the parameter information;

the parameter information may refer to configuration data, the main control board may first determine the configuration data corresponding to the controlled board, and then send the interface related information and the configuration data to the controlled board, and the controlled board may call the configuration interface to perform configuration operation according to the configuration data.

In practical applications, the system type and the device information are different, and the corresponding configuration data may be different, so that the master control board may determine the configuration data corresponding to the controlled board specifically according to the system type and the device information of the controlled board.

In addition, in order to improve the security, the main control board can also verify whether the controlled board is the permitted equipment according to the system type and the equipment information of the controlled board;

if the verification is successful, the configuration data corresponding to the controlled board can be determined again.
