[0043] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0044] like Figure 1 As shown, an embodiment of the present invention provides a multi-level mapping table interruption source optical fiber data transmission method, the method comprising:

[0045] Step 11, obtaining data transmitted to the node via the optical fiber;

[0046] Step 12, parsing the data to obtain the address corresponding to the data;

[0047] Step 13, according to the address, traverse the items in the first-level mapping table in the multi-level mapping table one by one in order to obtain a matching item, if the matching item is not obtained, traverse the next-level mapping table one by one in order until a matching item is obtained or all mapping tables are traversed; if the matching item is obtained, generate an interrupt source of a corresponding level according to the traversal history and the level of the matching item in the mapping table; the multi-level mapping table includes at least one group of data areas, each group of data areas includes at least one address and length;

[0048] Step 14: According to the interrupt source, the level and type of the interrupt source are obtained, and corresponding interrupt processing instructions are executed according to the level and type of the interrupt source.

[0049] In an embodiment of the present invention, data transmitted to the node through an optical fiber is obtained. Optical fiber is a channel for transmitting data, which has the characteristics of fast transmission speed and less data loss, and can transmit a large amount of data to the node in real time. The data is parsed to obtain the address corresponding to the data. The purpose of parsing the data is to find out the address information contained in the data, so as to facilitate the subsequent data processing. This operation can better understand the meaning and purpose of the data. According to the address, the items in the first-level mapping table in the multi-level mapping table are traversed one by one in order to obtain matching items, and an interrupt source of the corresponding level is generated. This process is to quickly find the required data in the case of complex data and improve the processing efficiency. At the same time, the generated interrupt source can focus on the important data and optimize the use of resources. According to the interrupt source, the level and type of the interrupt source are obtained, and the corresponding interrupt processing instruction is executed. This operation can perform different operations according to different interrupt sources, so that the data processing is more targeted. In addition, this can also classify and manage various types and levels of interrupt sources, and improve the efficiency and accuracy of data processing.

[0050] In a preferred embodiment of the present invention, the above step 11 may include:

[0051] Step 111, obtaining the number M of data regions and the number N of addresses contained in each data region;

[0052] Step 112, allocating required storage space to each data area for storing at least one address and length information corresponding to each address, wherein the length information includes a start position and an end position of the address and a length of a continuous address area from the start position to the end position;

[0053] Step 113, allocating a fixed storage location in each data area for each address and the length corresponding to each address according to the numerical value of the storage address, so as to form a multi-level mapping table with a length of N.

[0054] In an embodiment of the present invention, obtaining the number M of data regions and the number N of addresses contained in each data region helps to understand the overall structure and scale of the mapping table and create conditions for subsequent data storage and retrieval. Allocating the required storage space to each data region for storing at least one address and the length information corresponding to each address can ensure that each data region has enough space to store the address and length information, thereby avoiding data loss or confusion. Allocating a fixed storage location in each data region for each address and the length corresponding to each address according to the numerical value of the storage address to form a multi-level mapping table with a length of N can ensure that each address and length information has a fixed position in the mapping table, which is convenient for subsequent data retrieval and use. At the same time, the design of the multi-level mapping table can further improve the efficiency of data retrieval.

[0055] In a preferred embodiment of the present invention, the above step 112 may include:

[0056] Step 1121, obtaining the storage space required for each address information and length information;

[0057] Step 1122, allocating corresponding storage space to each data area according to the required storage space;

[0058] Step 1123, store corresponding length information for each address in the allocated storage space.

[0059] In an embodiment of the present invention, the storage space required for each address information and length information is obtained. This step will determine the required storage space according to the size and type of the data, which is helpful for the reasonable allocation and utilization of storage resources. According to the required storage space, the corresponding storage space is allocated to each data area. This step is based on the storage space requirements required for each address information and length information obtained in step 1121, and appropriate storage space is allocated to each data area to ensure the safe storage of data. In the allocated storage space, the corresponding length information is stored for each address. This step will store the corresponding length information for each address information in the storage space determined in each data area, thereby providing complete data information and facilitating the subsequent retrieval and use of data.

[0060] In a preferred embodiment of the present invention, the above step 13 may include:

[0061] Step 131, traverse the entire metadata table or status table in sequence to obtain the status of each data area;

[0062] Step 132, if the state of the first data area is idle or partially occupied, write new data into the first data area and jump to the next data area;

[0063] Step 133: If the status of the first data area is displayed as occupied, skip the first data area and continue to traverse the next data area.

[0064] In the embodiment of the present invention, by traversing the metadata table or the status table to obtain the status of each data area, the usage of each data area can be understood, so as to make better data management decisions; if the status of the first data area is idle or partially occupied, the new data will be written into this area, and then the program will jump to the next data area, so that efficient use of storage space can be achieved and space waste can be avoided; if the status of the first data area is occupied, the program will skip this area and continue to traverse the next data area. In this way, unnecessary operations on the occupied data area can be avoided, and the efficiency of data management can be improved.

[0065] In a preferred embodiment of the present invention, the above step 14 may include:

[0066] Step 141, traverse the mapping table again, find the storage area corresponding to the data, and obtain the physical address of the storage area;

[0067] Step 142, access the physical address, read the required data or write the data to the target address according to the length and format of the storage area;

[0068] Step 143, returning the read data to the requester, or writing the data to the target address, and then updating the mapping table.

[0069] In an embodiment of the present invention, the mapping table is traversed again to find the storage area corresponding to the data, and the physical address of the storage area is obtained, so that the actual storage location of the data can be determined, providing a basis for the subsequent data read and write operations. After obtaining the physical address, the system will access the physical address according to the length and format of the storage area, read the required data or write the data to the target address. This step can ensure the correct reading or writing of the data. The read data will be returned to the requester, or after the data is written to the target address, the system will update the mapping table, which is very important for data management and tracking, can ensure the accuracy and consistency of the data, and also make data access more efficient.

[0070] In a preferred embodiment of the present invention, after the above step 14, the following steps may be included:

[0071] Step 15, setting a priority for each interrupt source and mapping item;

[0072] Step 16, sorting the interrupt sources and mapping items according to their priorities to obtain a list of interrupt sources and mapping items in descending order of priority;

[0073] Step 17, selecting interrupt sources or mapping items one by one from the sorted list for processing.

[0074] In an embodiment of the present invention, a priority is set for each interrupt source and mapping item, so that the interrupt sources and mapping items can be managed with priority. This allows the system to process multiple interrupt sources and mapping items according to the priority, ensuring that high-priority interrupt sources and mapping items are processed first. According to the priority of the interrupt source and mapping item, the system sorts them to obtain a list of interrupt sources and mapping items in order from high to low priority, in order to effectively manage and schedule these resources when multiple interrupt sources and mapping items exist, ensuring the stable operation of the system. The interrupt sources or mapping items are selected one by one from the sorted list for processing, which has the advantage of ensuring that the interrupt sources and mapping items are processed in order according to the priority, ensuring that high-priority tasks can be processed first, and improving the response speed and processing efficiency of the system.
