Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1a is a flowchart of a first data storage method based on a transmission channel in an embodiment of the present application, and the embodiment of the present application is applicable to a case of storing data. The method is executed by a data storage device based on a transmission channel, the device is realized by software and/or hardware and is specifically configured in electronic equipment with certain data operation capability.
Fig. 1b is a first data storage scenario diagram in an embodiment of the present application, and with reference to fig. 1a and fig. 1b, the data storage method based on a transmission channel provided in this embodiment includes:
and S110, acquiring target data to be stored.
And S120, sending the target data to the opposite end through a transmission channel between the opposite end, so that the opposite end returns the target data through the transmission channel after receiving the target data.
For convenience of description, data to be stored is referred to as target data, and the target data may be data in various formats, such as pictures, texts, audios and videos, and the like. Specifically, the electronic device (which may be referred to as a local terminal) acquires target data to be stored, and the electronic device may be a terminal or a server.
As shown in fig. 1b, a transmission channel is established between the local terminal and another electronic device (which may be called an opposite terminal), and the transmission channel includes, but is not limited to, a wired network transmission channel, a wireless network (e.g., optical fiber) transmission channel, a radio frequency channel, a laser communication channel, a quantum communication channel, and the like. The other electronic device may also be a terminal or a server. The local terminal converts the target data into signals adaptive to the transmission channel, such as optical, electrical, magnetic and other signals in various forms, and then sends the signals to the opposite terminal through the corresponding transmission channel.
And the opposite terminal receives the target data to be stored, which is sent by the local terminal through the transmission channel. The target data is then returned through the transmission channel.
As shown in fig. 1b, the peer sends the target data to the home terminal through the transmission channel in response to that the target data does not satisfy the storage termination condition. The storage termination condition is a condition that the storage does not need to be continued, if the target data meets the storage termination condition, the target data does not need to be continued to be stored, and if the target data does not meet the storage termination condition, the target data needs to be continued to be stored.
Optionally, if the target data meets the storage termination condition, ending the operation, and the opposite end does not return the target data. And if the target data does not meet the storage termination condition, the opposite end returns the target data through the transmission channel.
And S130, receiving target data returned by the opposite terminal.

And S150, finishing the operation.
And after receiving the target data returned by the opposite terminal, the local terminal judges whether the target data meets the storage termination condition. The storage termination condition is a condition for terminating storage, if the target data meets the storage termination condition, the target data does not need to be stored continuously, and if the target data does not meet the storage termination condition, the target data needs to be stored continuously.
As shown in fig. 1b, if the target data meets the storage termination condition, the operation is ended, and the target data is not sent to the opposite end. And if the target data does not meet the storage termination condition, continuing to send the target data to the opposite terminal.
And then, the opposite terminal continues to receive the target data and responds that the target data does not meet the storage termination condition, and the target data is sent to the local terminal through the transmission channel. And the like, and the method is circularly executed.
In this embodiment, the local terminal and the peer terminal continuously receive and transmit the target data through the transmission channel until the target data meets the storage termination condition, so that the target data is transmitted on the transmission channel until the target data meets the storage termination condition, which is equivalent to storing the target data on the transmission channel by using the time delay of the transmission channel, as shown in fig. 1 c. The embodiment provides a data storage mode based on space and without an entity medium, realizes a brand new data storage mode for storing data in a transmission process, is not influenced by the cost, the service life and the service environment of a physical medium, and is beneficial to improving the storage performance. In a small-capacity product with a communication function, the storage resources of the product can be greatly expanded, the inherent unreliability problem of a real medium is reduced, and the performance of the product or equipment is remarkably improved.
According to the embodiment of the present application, fig. 2a is a flowchart of a second data storage method based on a transmission channel in the embodiment of the present application, and the embodiment of the present application is optimized based on the technical solutions of the above embodiments.

Optionally, before the operation "returning the operation of sending the target data to the opposite end through the transmission channel", additionally "performing setting processing on the received target data, where the setting processing includes at least one of reading, modifying, deleting, increasing, decreasing, and recoding".
Fig. 2b is a diagram of a second data storage scenario in an embodiment of the present application, and with reference to fig. 2a and fig. 2b, the data storage method based on a transmission channel provided in this embodiment includes:
and S210, acquiring target data to be stored.
S220, the target data is sent to the opposite terminal through a transmission channel between the opposite terminal and the target data, so that the opposite terminal can return the target data through the transmission channel after receiving the target data.
And S230, receiving target data returned by the opposite terminal.
In this embodiment, both the local end and the opposite end are embedded with a transceiving protocol, which specifies the receiving and sending operations of the target data. Based on this, the local terminal sends the target data to the opposite terminal through the transmission channel between the local terminal and the opposite terminal according to the receiving and sending protocol. And the opposite terminal receives the target data to be stored according to the receiving and sending protocol, and responds to the situation that the target data does not meet the storage termination condition, and sends the target data to the local terminal through a transmission channel. Optionally, the opposite end sends the target data to the opposite end through a transmission channel in response to the target data existing or the target data not meeting the deletion condition. The deleting conditions include, but are not limited to, arrival of a storage duration, invalidation or expiration of the target data, error of the target data, and the like, indicating that the target data needs to be deleted; on the contrary, if the target data does not satisfy the deletion condition, i.e. the storage duration is not reached, the storage duration is not expired, and the storage duration is correct, the sending operation needs to be continuously executed to continuously store the target data.
As shown in fig. 2b, before the peer end responds that the target data does not satisfy the storage termination condition and sends the target data to the peer end through the transmission channel, the peer end performs setting processing on the received target data, wherein the setting processing includes at least one of reading, modifying, deleting, increasing, decreasing and recoding. Specifically, the transceiving protocol of the opposite end further specifies the setting processing operation, and the opposite end performs the setting processing on the target data according to the transceiving protocol. And if the target data does not exist any more after being deleted, or the target data is lost in the transmission process under some special conditions, the opposite terminal responds to the absence of the target data and ends the operation. The increase and decrease is to increase or decrease the target data, and the recoding is to adopt a new coding rule to recode the target data after the target data is restored according to the original coding.
The local terminal receives the target data returned by the opposite terminal, and the received target data may be data originally sent by the local terminal or data after the opposite terminal performs the setting processing.
And S240, performing setting processing on the received target data, wherein the setting processing comprises at least one of reading, modifying, deleting, increasing, decreasing and recoding.
As shown in fig. 2b, similar to the transceiving protocol of the opposite end, the transceiving protocol of the local end also specifies the setting processing operation, and the local end performs the setting processing on the target data according to the transceiving protocol. For the explanation of the setting process, reference is made to the above description, and details are not repeated here.
And S250, judging whether the target data exists or not, or whether the target data does not meet the deleting condition or not. If the judgment result is yes, namely the target data exists and the target data does not meet the deleting condition, jumping to S220; if the judgment result is no, that is, the target data does not exist, or the target data meets the deletion condition, the process jumps to S260.
And S260, finishing the operation.
Optionally, the target data is deleted in S240 and then does not exist any more, or in some special cases, the target data is lost in the transmission process, and then the operation is ended.
In this embodiment, for the local terminal and the opposite terminal, if the target data exists and does not satisfy the deletion condition, the target data is sent to the transmission channel for storage, so that control of the storage life cycle of the target data based on the transmission channel is realized.
Furthermore, both the opposite terminal and the home terminal can set data in the transmission channel, and the functions similar to those in the storage process of the entity medium are realized through the setting processing.
According to the embodiment of the present application, fig. 3a is a flowchart of a third data storage method based on a transmission channel in the embodiment of the present application, and the embodiment of the present application is optimized based on the technical solutions of the above embodiments.
Optionally, a data relay station is configured on the transmission channel, and the operation "sending the target data to the peer end through the transmission channel between the target data and the peer end" is refined to "sending the target data to the data relay station through the transmission channel between the target data and the peer end" and forwarding the target data to the peer end through the data relay station "is performed.
Fig. 3b is a diagram of a third data storage scenario in an embodiment of the present application, and combining fig. 3a and fig. 3b, the data storage method based on a transmission channel provided in this embodiment includes:
and S310, acquiring target data to be stored.
And S320, sending the target data to a data transfer station through a transmission channel between the target data and the opposite terminal, and forwarding the target data to the opposite terminal through the data transfer station so that the opposite terminal returns the target data through the data transfer station after receiving the target data.
Specifically, the opposite end receives the target data and then sends the target data to the data transfer station through the transmission channel, and forwards the target data to the local end through the data transfer station.
Fig. 3b shows a data transfer station on a transmission channel. The data transfer station is configured with a buffer with limited storage space, such as 1GB, and when receiving the target data, the data transfer station temporarily stores the target data in the buffer, and reads and forwards the target data from the buffer. Since the buffer space of the data transfer station is limited, the target data is generally deleted after being transferred to release the buffer space. However, in the process of continuously receiving and transmitting the target data, the data transfer station also continuously stores the target data, so that the target data is stored in the data transfer station for a long time. It should be noted that the data transfer station in this embodiment is mainly responsible for transferring the target data, such as a router and a gateway, and does not have a large-capacity persistent storage medium such as a memory, that is, does not have a persistent storage capability, unlike a remote server having a persistent storage capability.
S330, receiving target data returned by the opposite terminal.
S340, judging whether the target data meet the storage termination condition, if so, jumping to S350, wherein the target data meet the storage termination condition; if the judgment result is no, that is, the target data does not satisfy the storage termination condition, the process returns to S320.
And S350, finishing the operation.
In the field of communications, a broad definition of a channel includes, in addition to the transmission medium, the associated equipment that transmits the signal. Based on this, the data transfer station is a part of the transmission channel, existing as a storage carrier of the target data; and continuously forwarding the target data through the data transfer station, so that the target data can share the storage carrier. With the increase of the number of data transfer stations and the increase of cache, the storage space can be continuously expanded. It should be noted that, the data transfer station may not be configured on the transmission channel, and the wireless transmission may be completely performed, and the target data is stored on the transmission channel and completely separated from any entity.
In the following embodiments of the above-mentioned embodiments, the data storage method based on a transmission channel further includes: and determining the data storage capacity of the transmission channel according to the time delay of the transmission channel and the channel capacity. Further, the acquiring target data to be stored includes: acquiring target data to be stored matched with the data storage capacity so as to fully utilize the storage space; or, the local terminal or the opposite terminal performs setting processing of changing data volume, such as modifying, deleting, increasing, decreasing, recoding and the like, on the received target data according to the data storage capacity, so that the processed target data volume does not exceed the data storage capacity and is equal to the data storage capacity as much as possible, the storage space is fully utilized, and meanwhile, data overflow is avoided.
The time delay of the transmission channel depends on the buffer or the time delay of the data transfer station, the spatial distance between the local terminal and the opposite terminal, the transmission efficiency, and the like. The channel capacity is the maximum information rate that a transmission channel can transmit without errors, in bits per second, which represents the maximum amount of information that can be transmitted per second. Based on this, the maximum amount of information that can be transmitted by the channel within the time delay range is calculated as the data storage capacity of the transmission channel. It can be seen that the longer the delay of the transmission channel, the larger the data storage capacity.
The data storage capacity in this embodiment is equivalent to the storage space of the entity medium, and is used to guide the acquisition and setting processing of the target data, ensure that the storage space is fully utilized, and avoid data overflow.
In the embodiment, the data storage capacity is obtained by a calculation method, and in some application scenarios, the time delay and the channel capacity are not easy to obtain, and data can be sent in the order of less data volume to more data volume until the data storage capacity is reached. Based on this, the embodiments of the present application optimize the operation of sending the target data based on the technical solutions of the above embodiments. Specifically, the sending the target data to the peer end through a transmission channel between the peer end and the peer end includes: dividing and packaging the target data to obtain a plurality of data packets; and sequentially sending the plurality of data packets to the opposite end through a transmission channel between the data packets and the opposite end according to the channel transmission rate until receiving the data packet which is returned by the opposite end and is sent for the first time in the plurality of data packets.
It is to be noted that, since the present embodiment involves transmitting the target data a plurality of times, the above-described optimization can be performed at least once of the transmission of the target data. Fig. 4a is a flowchart of a fourth data storage method based on a transmission channel in this embodiment, where the optimization is performed when the target data is sent for the first time after the target data is acquired.
Fig. 4b is a diagram of a fourth data storage scenario in this embodiment, and with reference to fig. 4a and fig. 4b, the data storage method based on a transmission channel provided in this embodiment includes:
and S410, acquiring target data to be stored.
And S420, segmenting and packaging the target data to obtain a plurality of data packets.
The target data is divided into a plurality of data fragments in accordance with a set size, for example 512 kb. And coding and encrypting each data fragment in the plurality of data fragments to obtain a plurality of data packets.
Optionally, the unique identification, arrangement and security coding is performed on the plurality of data packets. The data packet is uniquely identified to prevent the data packet from being lost, which is beneficial to the reproduction of the data packet. The data packets are arranged in the sequence from high to low in the urgency of storage, and the data packets with high urgency are sent preferentially to realize preferential storage. The security code ensures the security and reliability of the data packet.
And S430, sequentially sending the plurality of data packets to the opposite terminal through the transmission channel between the data packets and the opposite terminal according to the channel transmission rate.
The channel transmission rate is the amount of data that can be transmitted on the channel per unit time and is numerically equal to the number of bits transmitted per second that constitute the data code. Therefore, the number of packets to be transmitted per unit time (e.g., per second) is determined according to the channel transmission rate and the size of the packets, and then a plurality of packets are sequentially transmitted to the opposite end as time goes on.
As shown in fig. 4b, the data packets are transmitted every unit time; similarly, the opposite end receives the data packets at intervals of unit time. The data packet sent preferentially is received preferentially by the opposite terminal.
And the opposite terminal responds to the condition that the target data does not meet the storage termination condition, and sends the received data packet to the local terminal through a transmission channel. Similarly, the data packets received by the opposite terminal preferentially are also sent to the local terminal preferentially, and then the local terminal receives the data packets returned by the opposite terminal as time goes on.
S440, in the process of sending the plurality of data packets, judging whether a data packet which is returned by the opposite end and is sent for the first time in the plurality of data packets is received. If yes, namely, the data packet which is sent for the first time is received, the step is jumped to S451; if not, i.e. the first transmitted data packet is not received, the process continues to S430.
S451, stopping sending the data packet, and determining the data packet in the current transmission channel, which is called as the stored data packet. Execution continues with S460.
If the local terminal receives a data packet which is returned by the opposite terminal and is sent for the first time, the storage space of the transmission channel is full; the sending of new data packets should be stopped to avoid the situation of data packet overlapping. At this time, the data packet in the current transmission channel, that is, the transmitted data packet, is determined to be a stored data packet.
On the contrary, if the local terminal does not receive the first sent data packet returned by the opposite terminal, which indicates that the storage space of the transmission channel is not full, the local terminal can continue to send new data packets. Optionally, the number of the first transmitted data packets is at least one. It can be seen that the stored data packet may be all or part of a plurality of data packets divided by the target data. Fig. 4b shows that the target data is divided into 8 data packets, which are data packets 1-8, and the data packets are transmitted in the order of 1-8, and when the data packet 8 is transmitted, the first transmitted data packet 1 is received, and then 8 data packets are exactly the stored data packets.
And S460, receiving the stored data packet returned by the opposite terminal.
S470, judging whether the target data meet the storage termination condition, if so, jumping to S480, wherein the target data meet the storage termination condition; if the judgment result is no, that is, the target data does not satisfy the storage termination condition, S490 is executed.
And S480, finishing the operation.
And S490, sending the stored data packet to the opposite end through a transmission channel between the opposite end, so that the opposite end returns the stored data packet through the transmission channel after receiving the stored data packet. Execution continues with S460.
In the process of transmitting the data packet on the transmission channel, the signal enhancement technology and the distribution technology are used for ensuring that the data packet is successfully transmitted to the local terminal or the opposite terminal.
In this embodiment, the target data is divided into a plurality of data packets, and the data packets are sequentially sent until a data packet which is returned by the opposite end and is sent for the first time among the plurality of data packets is received, so that a transmission channel is fully utilized, and data superposition is avoided.

The method is executed by a data storage device based on a transmission channel, the device is realized by software and/or hardware and is specifically configured in electronic equipment with certain data operation capability. For convenience of description and distinction, the execution subject in the present embodiment is the opposite end in the above-mentioned embodiment, and is called the home end in the present embodiment, and in response, the opposite end in the present embodiment is the home end in the above-mentioned embodiment.
