step S2301: at least one adjacent supply storage space is selected from the plurality of supply storage spaces according to the transmission address.
Specifically, since the sending address is an IP address corresponding to the requiring user terminal, the login position of the requiring user terminal can be located through the IP address, and then the login position corresponding to each supplying user terminal is determined in the same manner, if the interval distance between the login position of the requiring user terminal and the login position of the supplying user terminal is smaller than the preset interval distance, the supplying user terminal is determined to be an adjacent supplying user terminal of the requiring user terminal, wherein the specific preset interval distance is not specifically limited in the embodiment of the present application, and can be set by related technicians. The number of adjacent supply storage spaces of the requiring user terminal may be one or more, and the specific number is not specifically limited in the embodiment of the present application.

When the time length matching value corresponding to each adjacent storage space is determined, the interval time length between the adjacent idle time length and the storage time length can be determined first, then the time length matching value corresponding to each adjacent storage space is determined according to the corresponding relation between the interval time length and the first matching value, and the corresponding relation between the interval time length and the first matching value can be that when the interval time length is lower than 2 days, the corresponding first matching value is 100%; for intervals longer than 2 days, and shorter than 5 days, the corresponding first matching value is 80%; when the interval is longer than 5 days and shorter than 10 days, the corresponding first matching value is 60%; when the interval time length is longer than 10 days, the corresponding first matching value is 40%, and the specific corresponding relation between the interval time length and the first matching value is not particularly limited in the embodiment of the application, and can be modified and set by related technicians.

The destination adjacent storage space of the data to be stored is selected through the sending address, so that the length of a transmission path of the data to be stored is reduced, the probability of data loss of the data to be stored in the transmission process is reduced, and finally, the target storage space is selected from the adjacent supply storage spaces through feature matching, so that the accuracy in determining the target storage space is improved.
Step S240: and determining the supply storage space with the highest matching value as a target storage space of the data to be stored.
Specifically, after determining the matching value corresponding to each supply storage space, the highest matching value may be determined after all the supply storage spaces are sorted according to the bubbling sorting method, or the matching values of all the supply storage spaces may be traversed and compared with the maximum matching value recorded currently, if a larger matching value is found, the maximum matching value is updated, and the specific manner of determining the maximum matching value is not specifically limited in the embodiment of the present application, as long as the target storage space with the highest matching value can be determined from a plurality of supply storage spaces.
For the embodiment of the application, the target storage space is determined together through the demand quantity, the storage duration and the storage security level of the data to be stored, instead of randomly selecting the target storage space according to the storage data quantity, the matching degree of the target storage space and the data to be stored is conveniently improved and determined by increasing the selection condition, and the free storage space is provided by the supply user terminal, namely, the data to be stored is finally stored in the free storage space in the supply user terminal, instead of directly storing the data to be stored in the cloud space, and the cloud space is often used as an attack target, so that the storage of the data to be stored in the free storage space in the supply user terminal is convenient for improving the security of the data to be stored in the storage process.
Further, in order to facilitate the relevant technicians to more intuitively understand the resource usage situation of each supply storage space, the method provided by the embodiment of the application further includes:
acquiring the storage residual quantity of each supply storage space, and generating a supply storage chain based on each storage residual quantity, wherein the supply storage chain comprises a plurality of nodes, and each node corresponds to one supply storage space; acquiring the use information of each supply storage space in the supply storage chain in real time, wherein the use information is the time and the data volume of writing data into or taking out data from the supply storage space; and updating the supply storage chain according to the use information of each supply storage space, and feeding back the updated supply storage chain.
Specifically, the storage remaining amount of each of the supply storage spaces is a free capacity of the supply storage spaces, and since the data processing operation corresponding to each of the supply storage spaces at different times is different, data may be written or data may be released, and thus the storage remaining amount of each of the supply storage spaces may change with time. The adjacent nodes in the supply storage chain have no upper-lower corresponding relation, can be ordered according to the time when different supply user terminals provide idle storage space for the electronic equipment, can also be randomly ordered, and is not limited in the embodiment of the application. Typically, one feed user terminal corresponds to one feed storage space, and thus, each node in the feed storage chain corresponds to one feed user terminal.
The usage information of the supply storage space may be recorded by a log corresponding to the supply terminal device and uploaded to the electronic device, or the electronic device may directly record the time and the data amount of writing data or taking out data corresponding to the supply terminal device, which is not particularly limited in the embodiment of the present application. The supply memory chain is updated according to the usage information of each supply memory space, that is, the storage remaining amount of the corresponding supply memory space in the supply memory chain is updated according to the time of writing data or taking out data of each supply memory space and the data amount, and the supply memory chain may be updated in real time or periodically, for example, may be updated every 20 hours, and the specific updating mode is not particularly limited in the implementation of the present application.
When the updated supply storage chain is fed back, the updated supply storage chain can be directly fed back to a display interface of the electronic equipment, and the storage residual quantity corresponding to each node in the updated supply storage chain can be fed back after being tidied in a text description mode, and the specific feedback mode is not particularly limited in the embodiment of the application, so long as the application can be conveniently referred to by related technicians.
Further, in order to reduce the packet loss in the data storage process, the method provided by the embodiment of the application further comprises the following steps:
acquiring the borrowing information corresponding to each node, and generating a borrowing list according to the borrowing information corresponding to each node, wherein the borrowing information is used for representing the borrowing time period and the borrowing space of each supply storage space; the inventory of each node is added to the supply chain.
Specifically, if different data to be stored are written into the same supply storage space at the same time, the data may be written abnormally due to the writing conflict, so that the data is lost or covered in the writing process, and the use condition of the supply storage space corresponding to each node is more intuitively shown by generating a borrowing list, as shown in fig. 4, each borrowing list further comprises a corresponding use state besides the storage residual quantity of the supply storage space, wherein the supply storage space can be determined to be in a writing state or an idle state according to the borrowing time period. When the borrowing time period comprises the current time, the working state corresponding to the borrowing time period is represented as a writing state; and when the borrowing time period does not contain the current time, representing that the working state corresponding to the borrowing time period is an idle state.
The lending condition of each node is added in the supply storage chain, and the balance condition is displayed in the supply storage chain in the form of an information list, so that relevant staff can more intuitively check the lending condition of each supply storage space, and can check whether conflict lending exists or not through the lending information, and the situation of packet loss in the data storage process can be reduced through reduction of storage conflicts.
Further, when the number of the initially supplied storage spaces is 0, it may be necessary to write the data to be stored in a manner of merging the supplied storage spaces, and in order to facilitate the improvement of the security when the data to be stored is written into the merged storage spaces, the method provided by the embodiment of the present application further includes:
when the target storage space does not exist, sequencing the plurality of the supply storage spaces according to the matching value corresponding to each supply storage space to obtain a supply sequence; determining at least one combined storage space according to the supply sequence, wherein the number of the supply storage spaces contained in each combined storage space is not higher than the number of the preset spaces; acquiring a historical communication record of each supply storage space in the supply sequence, and determining the corresponding credibility of each combined storage space according to the historical communication record of each supply storage space; and determining the combined storage space with the reliability higher than the preset reliability as a target combined storage space, and determining the target combined storage space as a target storage space of the data to be stored.
Specifically, when determining the supply sequence according to the matching value corresponding to each supply storage space, the specific ordering manner may be not specifically limited in the embodiment of the present application, as long as the supply sequence can be obtained, when using the bubbling ordering, an initial sequence may be randomly generated first, then the matching values corresponding to two adjacent supply storage spaces in the initial sequence may be compared, if the order is not right, the positions are exchanged, and the process is repeated until the whole initial sequence is ordered.
When determining the merging storage space, selecting according to the sequence from small to large of the matching value, for example, the feeding sequence contains 5 feeding storage spaces, namely A, B, C, D and E, wherein the merging storage space can be AB, AC, AD, ABC, the number of preset spaces can be 3 or 4, when the number of preset spaces is 3, the maximum of 3 feeding storage spaces can be represented in the merging storage space, and the number of the feeding storage spaces in the merging storage space is limited due to the fact that data can be lost in the writing process, so that the data writing times are reduced, and the integrity of the data is improved conveniently.
The history communication record of the supply storage space is a record that the supply user terminal corresponding to the supply storage space communicates with other supply user terminals in a history period, and the history period may be one week in the past or one month in the past, and is not particularly limited in the embodiment of the present application, and may be set by a related technician. The more the number of historical communications corresponding to two supply user terminals in the historical time period, the higher the credibility between the two supply user terminals is represented, when the credibility between the two supply user terminals is determined, the determination can be performed according to the corresponding relation between the number of communications and the credibility, for example, when the number of communications in the historical time period is less than 5 times, the corresponding credibility is 20%; when the communication times in the historical time period are 5-10, the corresponding reliability is 30%; when the number of communications in the historical time period is more than 10, the corresponding reliability is 50%, and the correspondence between the number of communications and the reliability is not particularly limited in the embodiment of the present application, and may be set by a related technician. The preset credibility may be 85% or 90%, and the specific preset credibility is not specifically limited in the embodiment of the present application, and whether different supply storage spaces can be combined or not is determined by the credibility between the supply storage spaces in the combined storage space, so that the security when the data to be stored is written into the combined storage space is improved conveniently.
Further, in order to facilitate improving data integrity, the method provided by the embodiment of the application further includes:
when the supply user terminal corresponding to the target storage space is abnormally powered off, determining a borrowing terminal corresponding to the abnormally supplied user terminal according to the supply storage chain, wherein the borrowing terminal is a demand user terminal for writing data to be stored into the target storage space corresponding to the abnormally supplied user terminal; acquiring a storage state of each borrowing terminal, wherein the storage state comprises storage and storage completion; pushing a data verification instruction to the borrowing and storing terminal with the storage state being stored so as to remind relevant staff to verify the data which is abnormally written and supplied to the user terminal.
Specifically, when the supply user terminal corresponding to the target storage space fails abnormally, the data to be stored in the target storage space may be lost, and at this time, the user terminal needs to be reminded of relevant requirements to detect the integrity of the data to be stored in the target storage space. Different requiring user terminals can write data to be stored in the free storage space provided by the same supplying user terminal, for example, the supplying user terminal A provides 50% of solid state disk capacity, at this time, the requiring user terminal A and the requiring user terminal B both write data to be stored to the supplying user terminal A at different moments, the requiring user terminal A and the requiring user terminal B are borrowing terminals of the supplying user terminal A, and the number of the requiring user terminals in the borrowing terminals may be one or multiple.
When the storage state of each borrowing terminal is determined, the corresponding writing data quantity of each borrowing terminal can be determined through the work log of the electronic equipment, and if the writing data quantity is consistent with the storage demand quantity of the corresponding data to be stored, the storage state of the borrowing terminal is characterized as storage completion; and if the written data quantity is lower than the storage demand quantity of the corresponding data to be stored, characterizing that the storage state of the borrowing and storing terminal is in storage. When a data verification instruction is pushed to the borrowing terminal in a storage state, the communication address of each borrowing terminal can be acquired first, then pushing is carried out based on the communication address of each borrowing terminal, and related technicians are conveniently reminded of verifying data which possibly have abnormality through the data verification instruction, so that the probability of losing the data due to abnormal power failure is reduced.
