Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to solve the problem that the transmission efficiency is low because all the DCP data copied by the video hall playing clients are pulled to the management server in the prior art, the embodiments of the present invention provide a data transmission method, apparatus and system, which implement data sharing transmission in the local area network and improve the data transmission efficiency.
Example one
An embodiment of the present invention provides a data transmission method, a flow of which is shown in fig. 1, and the method includes the following steps:
step S11: when the management server determines that the client needs to copy the data, the management server determines a data source from the management server and the client which has copied the data according to a preset rule, determines a client to be copied from the client which needs to copy the data, and determines a corresponding relation between the data source and the client to be copied.
In one embodiment, the determining, by the management server, that there is a client that needs to copy the data may include:
the management server judges whether the client-side uncopyed data exist or not according to a preset interval, and if so, the management server determines that the client-side needs to copy the data; or
After receiving a copy completion notification sent by any one or more clients, the management server judges whether the clients copy data or not, and if so, determines that the clients need to copy the data; or the like, or, alternatively,
after receiving all current clients to be copied and sending copy completion notifications, the management server judges whether the clients have data which are not copied, and if so, determines that the clients need to copy the data; or the like, or, alternatively,
when the management server receives a copy request sent by the client, the management server determines that the client needs to copy data.
That is, the management server determines that there is a client that needs to copy data, and may actively execute according to a preset interval or passively execute the last three modes.
When the data transmission is performed passively, a copy completion notification sent by a client to be copied can be received, or a copy request sent by the client can be received, wherein the former needs to judge whether the client needs to copy data, and the latter needs not to judge and directly performs the data transmission step.
Receiving a copy completion notification sent by a client to be copied, wherein the copy completion notification can be sent by one or more clients, judging whether the client needs to copy data or not, if so, continuing to execute the subsequent steps; or after receiving all the current clients to be copied and sending the copy completion notification, judging whether the clients need to copy the data or not, if so, continuing to execute the subsequent steps. The former needs shorter total time for data transmission than the latter, but the data transmission process of the latter is easy to manage. The details of the two ways are described in detail in examples 2 and 3 below.
Optionally, the management server determines that there is a client that needs to copy data, or may be triggered by other trigger conditions, and the specific implementation is not limited.
Step S12: and informing the client to be copied to copy the data from the corresponding data source according to the corresponding relation.
Specifically, the address of the data source may be sent to the client to be copied according to the client to be copied and the data source corresponding to the corresponding relationship, so that the client to be copied may copy the data from the data source according to the received address.
The above steps are executed circularly until no client needs to copy the data, that is, all clients copy the data.
The embodiment of the invention is suitable for a scene that a plurality of clients need to copy the same data from the server, and the traditional method is that the clients queue to copy the data from the server in sequence, so the time consumption is longer, and the single-point bandwidth becomes a transmission bottleneck. In the data transmission method provided by the embodiment of the invention, when a management server determines that a client needs to copy data, a data source is determined from the management server and the client which has copied the data according to a preset rule, a client to be copied is determined from the client which needs to copy the data, and the corresponding relation between the data source and the client to be copied is determined; and informing the client to be copied to copy the data from the corresponding data source according to the corresponding relation. And the client which finishes copying the data are used as data sources circularly until all the clients finish copying the data, so that the data sharing transmission in the local area network is realized, and the data transmission efficiency is improved.
For example, a management server (hereinafter, referred to as a server) has a packet of 400GB, a total of 10 clients, and a bandwidth of 1000Mbps ≈ 125MB/s, and then it takes 400 × 1024 × 10 ÷ 125 ÷ 60 ÷ 60 ≈ 0.91 hours × 10 ≈ 9.10 hours, which is about the time of one working day, to transmit the packet using the conventional method. If the data transmission method provided by the embodiment of the invention is used, for example, after the management server receives all the current clients to be copied and sends the copy completion notification, whether the clients copy data or not is judged, and if so, data transmission is executed. If the initial transmission data source is only a server, the time for copying the data packet by the first client (marked as client 1) is 0.91 hour; after the client 1 finishes copying, the number of transmission data sources is increased to 2 in the client 1 and the server, so that the clients 2 and 3 can download at the same time; after the clients 2 and 3 finish downloading, the number of transmission data sources is increased to 4, so that the clients 4, 5, 6 and 7 can download at the same time; after the downloading of the clients 4, 5, 6 and 7 is completed, the number of the transmission data sources is increased to 8, and the clients 8, 9 and 10 can be simultaneously downloaded. It can be seen that this is a tree with a layer height of 4, the total transmission time is 4 × 0.91 h ≈ 3.64 h, and the transmission speed is increased by 2.5 times. And as the number of clients increases, the transmission efficiency improvement index increases. For example, 15 clients exist, and the transmission time of the conventional method needs 0.91 hour × 15 — 13.65 hours; in the data transmission method provided in the first embodiment of the present invention, when the number of transmission data sources is increased to 8, the clients 8 to 15 can download the data packets at the same time, so that the time required for transmission is still 3.64 hours, and the transmission speed is increased by 3.8 times.
Example two
The second embodiment of the present invention provides a specific implementation of a data transmission method, a flow of which is shown in fig. 2, and the method includes the following steps:
step S21: the management server determines a client to be copied and informs the client to be copied to copy data from the management server.
The specific determination method may be that the management server randomly selects one client from the clients connected to the management server as the client to be copied; preferably, according to the network signal strength, one client to be copied is selected from the connected clients, for example, one client with the strongest network signal strength is selected from the connected clients as the client to be copied; optionally, other determination rules may be used, and the specific determination method of the client to be copied is not limited in this embodiment.
Step S22: and after receiving a copy completion notification sent by the client to be copied, marking the client sending the copy completion notification as copied.
Step S23: and judging whether the client needs to copy the data or not.
That is, it is determined whether any client is not marked as copied, if yes, step S24 is executed; if not, step S28 is executed to complete the data transmission.
Step S24: the data source is determined from itself and the clients marked as copied.
In one embodiment, the method may include determining that a network in the client that is marked as copied is idle as an alternative data source; when the number of the alternative data sources is larger than that of the clients needing to copy the data, screening the data sources with the number equal to that of the clients needing to copy the data from the alternative data sources according to the network signal strength; and when the number of the alternative data sources is not more than that of the clients needing to copy the data, determining all the alternative data sources as the data sources.
Preferably, in an embodiment, determining that the network is idle in the client and the client marked as copied, and the client whose network signal strength meets a preset condition is an alternative data source; when the number of the alternative data sources is larger than that of the clients needing to copy the data, screening the data sources with the number equal to that of the clients needing to copy the data from the alternative data sources according to the network signal strength, for example, screening the data source with the strongest network signal strength; and when the number of the alternative data sources is not more than that of the clients needing to copy the data, determining all the alternative data sources as the data sources.
In the determination method of the two data sources, the latter has more limitation that the network signal strength meets the preset condition than the former, and the two data sources are not distinguished under the condition that the alternative data source with the network signal strength meeting the preset condition is sufficient; when the number of the alternative data sources with the network signal strength meeting the preset condition is less than that of the clients needing to copy the data, the management server and all the clients with copied data are used as data sources in the alternative data sources, and only the clients with the network signal strength meeting the preset condition are used as data sources in the alternative data sources. The latter avoids the situation that the data transmission is slow and even some clients can not complete data copy because the network signal strength is too weak as a data source; the former management server has a relatively small calculation amount for data transmission management, and therefore, both management servers have advantages.
Step S25: determining a client to be copied from clients needing to copy data, and determining a corresponding relation between a data source and the client to be copied.
When the number of the data sources is greater than or equal to the number of the clients needing to copy the data, it may be determined that all the clients needing to copy the data are the clients to be copied.
When the number of the data sources is less than the number of the clients needing to copy the data, determining the clients to be copied, the number of which is equal to the number of the data sources, from the clients needing to copy the data according to the network signal strength; or determining the clients to be copied, the number of which is not more than the number of the data sources, of which the network signal strength meets the preset condition from the clients needing to copy the data.
In one embodiment, the method may include selecting a data source matching the copy right according to the copy right of the client to be copied, and establishing a corresponding relationship with the client to be copied.
Specifically, selecting a data source matched with the copy right according to the copy right of the client to be copied may include: determining a data source capable of providing copy data matched with the authority level according to the authority level in the copy authority; and/or, according to the file type in the copying authority, selecting a data source which can provide the copied data matched with the file type.
The authority levels may include general users, general members, high-level members, and the like, and the contents of the copyable data corresponding to different authority levels are different, for example, some data are only opened for high-level members, and some data are only opened for high-level members and general members. Or, the types of the copyable data corresponding to different permission levels are different, taking a certain movie data as an example, the high definition version is only opened for general members and high-level members, and the common definition version is opened for all users, that is, the common user can only copy the movie data of the common definition version. Alternatively, the content and type of the copyable data may be different for different levels of rights.
Therefore, only the client with the copy right can copy the corresponding data.
Step S26: and informing the client to be copied to copy the data from the corresponding data source according to the corresponding relation.
Step S27: and determining that all current clients to be copied send copy completion notifications, and marking the clients sending the copy completion notifications as copied clients.
Specifically, after receiving a copy completion notification sent by a client to be copied, the client sending the copy completion notification may be marked as copied; or after all the current clients to be copied send copy completion notifications, all the clients sending the copy completion notifications are marked as copied.
After determining that all the current clients to be copied finish copying the data, step S23 is executed to determine whether any client needs to copy the data.
Step S28: and finishing data transmission.
EXAMPLE III
The third embodiment of the present invention provides another specific implementation of a data transmission method, and a flow thereof is shown in fig. 3, and includes the following steps:
step S31: the management server determines a client to be copied and informs the client to be copied to copy data from the management server.
Step S32: and after receiving a copy completion notification sent by the client to be copied, marking the client sending the copy completion notification as copied.
Step S33: it is determined whether there is a client unmarked copied copy and in an unmarked copy.
If yes, go to step S34; if not, step S38 is executed to complete the data transmission.
Step S34: determining a data source from the client which is marked as copied but not marked as copied, and marking the data source as copied.
Step S35: and determining a client to be copied from the clients which are not marked with copies, marking the client to be copied as a copy, and determining the corresponding relation between the data source and the client to be copied.
Step S36: and informing the client to be copied to copy the data from the corresponding data source according to the corresponding relation.
Step S37: and receiving a copy completion notification sent by one or more clients to be copied, and marking the client sending the copy completion notification as copied.
After the client that sent the copy completion notification is marked as copied, step S33 is executed to determine whether there is a client that needs to copy data.
Step S38: and finishing data transmission.
In the third embodiment, after receiving the copy completion notification sent by the one or more clients to be copied each time, the data source and the clients to be copied are continuously determined, and the clients to be copied are notified to download data from the data source, so that the data transmission time is further saved, and the data transmission efficiency is improved.
The steps in the third embodiment are the same as or similar to those in the second embodiment, and are not described again.
Example four
A fourth embodiment of the present invention provides a specific application of a data transmission method, which is applied to transmission of a Digital Cinema Package (DCP) in a Theater Management System (TMS), that is, a method for a theater Management server to transmit a Digital Cinema Package, and specifically includes: when the cinema management server determines that a playing client needs to copy the digital movie package (DCP), determining a data source from the cinema management server and the playing client which has copied the data according to a preset rule, determining a client to be copied from the playing client which needs to copy the data, and determining a corresponding relation between the data source and the client to be copied; and informing the client to be copied to copy the DCP from the corresponding data source according to the corresponding relation.
Specifically, the data transmission method in the foregoing embodiment can be applied to the method for transmitting the digital cinema package by the cinema management server in the fourth embodiment.
The specific implementation process, taking the steps shown in fig. 4 as an example, assumes that there are 4 playing clients (playing servers) that need to copy the DCP, and the specific steps may include:
1.1 first, the DCP is imported to the hard disk of the TMS management server.
1.2 the transport coordinator of the management server informs the playout server (playout server 1 in fig. 4) to copy the DCP from the TMS.
Here, the playing server is the server of the playing client.
2.1 Player Server 1 copies the DCP from the TMS.
2.2 after the broadcast server 1 finishes copying the DCP, the transmission coordinator is notified that the copying is finished, and the transmission coordinator marks that the broadcast server 1 finishes the transmission.
3.1 the transfer coordinator (the transfer server in fig. 4 is the transfer coordinator) informs the playout server 2 to copy the DCP from the playout server 1 and sends the destination address, i.e. the address of the playout server 1, to the playout server 2.
3.2 Play Server 2 copies the DCP from Play Server 1 according to the received address.
3.3 Player Server 2 informs the transfer coordinator that the copy has been completed, and the transfer coordinator marks that Player Server 2 has finished transferring.
4.1 the transport coordinator informs the playout server 3 to copy the DCP from the TMS.
