fig. 2 is a schematic diagram illustrating splitting of original data in a data transmission method according to an embodiment of the present invention;
fig. 3 is a schematic diagram of data packet allocation in a data transmission method according to an embodiment of the present invention.
As shown in fig. 1, in one aspect, the present invention provides a data transmission method applied to a server, where the method includes:
103, receiving a data downloading request of a first client for a required data packet;
104, positioning a second client storing the required data packet according to the received data downloading request;
In this embodiment, first, the original data is split into a plurality of data packets, where the original data is a complete file that needs to be transmitted to other clients, and the data sizes of the plurality of data packets may be equal or unequal, and specifically, as shown in fig. 2, fig. 2 shows one of the ways of splitting the original data, specifically, one of the ways of splitting one original data into 17 data packets, and numbers each data packet.
Then, distributing the divided multiple data packets to multiple clients for storage respectively, and recording data packet information stored in each client, where the distribution mode may be random distribution, or may be distribution according to data packet numbers in sequence, specifically, as shown in fig. 3, fig. 3 shows one of the situations of random distribution of original data, and in fig. 3, the data packets distributed to the client 1 are data packet 1, data packet 2, and data packet 4; the data packets distributed by the client 2 are data packet 2, data packet 9 and data packet 10; the data packets distributed by the client 3 are data packets 1-7, data packet 11 and data packet 12; the data packets distributed by the client 4 are data packets 5, 6, 8 and 11-13; the data packets 14-17 are temporarily unassigned. After the distribution is finished, the data packet information stored by each client is recorded.
And then receiving a data downloading request of the first client for the required data package, wherein the data downloading request is generated by the client according to the data package condition of the first client, and it is emphasized that the first client refers to all downloading requesters, not to the client 1 in fig. 3.
Then, according to the received data download request, the second client having the required data package is located, taking the client 2 in fig. 3 as an example, assuming that the client 2 issues a data download request for the data package 3, and the server locates the client 3 having the data package 3 according to the data download request of the client 2, it should be emphasized that the second client refers to the client having the corresponding data package instead of the client 2 in fig. 3.
And finally, instructing the corresponding second client to transmit the required data packet to the first client, specifically, sending a data transmission instruction for the required data packet to the second client, and instructing the second client to transmit the required data packet to the first client by using the intermediate server.
Therefore, in the process of file transmission, data transmission is carried out between the client side and other client sides by using the resources of the client side, the data transmission pressure of the server side is reduced, and the transmission efficiency is further improved.
Furthermore, in order to further improve the transmission efficiency, the data packets obtained by splitting in the server are all loaded into the memory of the server, and when data transmission is needed, the data are directly obtained from the memory of the server.
In an embodiment, the method further comprises:
and if the second client side with the required data packet is not located, transmitting the required data packet in the local memory to the first client side.
In this embodiment, it should be emphasized firstly that when the server allocates the data packets, especially randomly, one or more data packets in the server may not be allocated to any client, so that the required data packets do not exist in any client; there is also a case where the client contains the required packet, but due to memory size limitations, the required packet is not loaded into the memory of the client, which will also result in the server failing to locate the client.
Therefore, if the second client side with the required data packet is not located, the required data packet in the memory of the server is transmitted to the first client side, so that the required data packet is transmitted to the first client side.
In an embodiment, the locating to the second client storing the required data package according to the received data download request includes:
inquiring the client side with the required data packet in all the client sides;
and selecting the client with the minimum current transmission pressure from the inquired clients as a second client for providing corresponding data packet transmission.
In this embodiment, the specific process of step 104 is:
the client side storing the required data packet in all the client sides is queried, and specifically, the client side storing the required data packet can be queried according to the recorded and stored data packet information.
If a plurality of clients meeting the conditions are inquired, the client with the minimum current transmission pressure is selected as a second client providing corresponding data packet transmission, wherein the minimum current transmission pressure can be defined as the minimum current processor occupancy rate or the minimum current transmission task quantity.
Therefore, the client with the minimum current transmission pressure is preferably selected as the second client for data packet transmission, so that the transmission pressure between the clients can be effectively reduced, and the transmission efficiency is further improved.
In an embodiment, after instructing the second client to transmit the required data packet to the first client, the method further comprises:
and updating the existing data packet information in the first client.
In this embodiment, after the second client is instructed to transmit the required data packet to the first client, the existing data packet information for the first client is updated at the server, so that the server can know the data packet condition in the client at the next time of receiving the download request, which is beneficial to improving the transmission efficiency.
Fig. 4 is a schematic flow chart illustrating an implementation of a data transmission method applied to a client according to an embodiment of the present invention;
as shown in fig. 4, another aspect of the embodiments of the present invention provides a data transmission method, applied to a client, where the method includes:
In this embodiment, first, according to original data information and local existing data packet information, required data packet information is determined, where the original data information includes complete data packet information, and this step is to specifically check the original data information and the existing data packet information in the current client one by one, and determine the required data packet information, where the number of the data packets to be determined is generally one, and certainly may be multiple;
and then generating a data downloading request aiming at the required data package information according to the determined required data package information.
Then sending the generated data downloading request to a server side so that the server side can search for the client side containing the required data packet in other client sides; if the client containing the required data packet is searched from other clients, the client is utilized to transmit the required data packet to a local memory through an intermediate server; and if the client containing the required data packet is not searched from other clients, downloading the required data packet to the local memory from the memory of the server.
Further, after the required data packet is stored in the local memory, the data packet in the local memory is copied to the local hard disk.
In one implementation, the original data information includes data packet information and corresponding data location information, and the data packet information and the data packets correspond one to one;
determining required data packet information according to original data information and local existing data packet information, wherein the required data packet information comprises the following steps:
determining all missing data packet information according to the original data information and the local existing data packet information;
and determining the missing data packet information with the previous data position as the required data packet information from all the missing data packet information.
In this embodiment, each packet information corresponds to a data location information, wherein the data location information is the same as the packet number mentioned above, referring to fig. 3, the data location corresponding to the data packet 1 is the first, the data location corresponding to the data packet 2 is the second, and the data location corresponding to the data packet 17 is the last.
Thus, the specific process of step 201 is:
determining all missing data packet information according to the original data information and the local existing data packet information, specifically checking the original data information and the existing data packet information in the current client one by one to determine all missing data packet information;
and then determining the missing data packet information with the previous data position as the required data packet information from all the missing data packet information.
Taking the client 2 in fig. 3 as an example, assuming that existing data packets in the memory and the hard disk of the client 4 are the data packet 2, the data packet 9, and the data packet 10, then the data packets except the data packets 2, 9, and 10 are all missing data packet information, and then the data packet 1 is preferentially selected from all the missing data packet information as the required data packet information.
The benefits of this step are: the client side can preferentially download the data packet with the front data position, and the client side can decompress the data packet with the front data position first, so that the installation efficiency is improved. Taking the client 2 in fig. 3 as an example, assuming that the current client has only the data packets 2, 9, and 10, after the client downloads the data packet 1, the client can decompress the consecutive data packets 1 and 2, the decompression operation is suspended after the current decompression is completed, the downloading of the data packet 3 is waited, and the decompression operation can be continued on the data packet 3 after the data packet 3 is downloaded, thereby improving the installation efficiency.
In an implementation manner, in the process of downloading the required data packet from other clients or from the server to the local memory, the method further includes:
judging whether the residual storage space in the memory can store the required data packet or not;
and if the residual storage space in the memory is judged not to be capable of storing the required data packet, releasing the data packet with the prior timestamp stored in the memory until the required data packet can be stored in the memory.
In this embodiment, because it is considered that the memory of the client is small and may not be enough to store all the data packets, in the process of downloading the required data packets from other clients or from the server to the local memory, it is determined whether the remaining storage space in the memory can store the required data packets; and if the residual storage space in the memory is judged not to be capable of storing the required data packet, releasing the data packet with the prior timestamp stored in the memory until the required data packet can be stored in the memory.
In one embodiment, after downloading the required data packet to the local memory, the method further includes:
and sending the local existing data packet information to the server so that the server can record the existing data packet information of the current client.
In this embodiment, after the required data packet is downloaded to the local memory, the local existing data packet information is sent to the server, so that the server records or checks the existing data packet information of the current client, and the existing data packet of each client can be known exactly in the subsequent data transmission.
In an embodiment, the method further comprises:
and receiving and responding to a data uploading request sent by the server, wherein the data uploading request is used for uploading a specified data packet in the memory to a specified client.
In this embodiment, the client is further configured to receive and respond to a data upload request sent by the server, where the data upload request includes an assigned data packet and an assigned client, and the step specifically includes selecting the assigned data packet according to the received data upload request, and then transmitting the assigned data packet to the assigned client.

Then, the data packet allocation module 302 allocates the divided data packets to a plurality of clients for storage respectively, and records the data packet information stored in each client, where the allocation manner may be random allocation or allocation according to the data packet numbers in sequence, specifically, as shown in fig. 3, fig. 3 shows one of the cases of random allocation of the original data, and in fig. 3, the data packets allocated to the client 1 are data packet 1, data packet 2, and data packet 4; the data packets distributed by the client 2 are data packet 2, data packet 9 and data packet 10; the data packets distributed by the client 3 are data packets 1-7, data packet 11 and data packet 12; the data packets distributed by the client 4 are data packets 5, 6, 8 and 11-13; the data packets 14-17 are temporarily unassigned. After the distribution is finished, the data packet information stored by each client is recorded.
Next, a data download request of the first client for the required data package is received through the data download request receiving module 303, where the data download request is generated by the client according to the data package condition of the first client, it is emphasized that the first client refers to all download requesters, and is not the client 1 in fig. 3.
Then, the client location module 304 locates a second client storing the required data package according to the received data download request, taking the client 2 in fig. 3 as an example, assuming that the client 2 sends a data download request for the data package 3, and the server locates the client 3 containing the data package 3 according to the data download request of the client 2, it should be emphasized that the second client refers to the client containing the corresponding data package instead of the client 2 in fig. 3.
Finally, the transmission instruction module 305 instructs the corresponding second client to transmit the required data packet to the first client, specifically, may instruct the second client to transmit the required data packet to the first client by means of the intermediate server, by sending a data transmission instruction for the required data packet to the second client.
Therefore, in the process of file transmission, data transmission is carried out between the client side and other client sides by using the resources of the client side, the data transmission pressure of the server side is reduced, and the transmission efficiency is further improved.
