The terms "first," "second," "third," "fourth," and the like in the description and in the claims of the present application and in the drawings described above, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus. The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments.
In the current cloud desktop system, as shown in fig. 2 and 3, a local end establishes a connection with a server, when the local end performs a copy operation, the server sends a clipboard format list to the local through a connection channel between the local desktop and a remote desktop, and after the local end receives the clipboard format list, the local end injects the clipboard format list sent by the server into a local system clipboard. But if the paste data content is very large, for example, a file has a size of several G to several tens G. At this time, the local desktop triggering and pasting, such as the file manager, does not issue a request for file contents of several G to several tens G at a time, but requests the file contents through the system clipboard uniformly and orderly by sub-packaging one by one. The specific data request response flow is shown in fig. 3, after the paste operation is performed on the local desktop, the file manager on the local desktop requests a file content with a certain size through the system clipboard, the request is firstly sent to the remote end through the connecting channel of the local and remote desktops, the remote end receives the request, collects the 4K file content, and then returns the 4K file content data to the data request end of the local desktop through the connecting channel of the local and remote desktops. After receiving the 4K file content, actively triggering a second 4K file content request. When the file content is large, the process of transmitting the file with the same size of 4K is repeated for n times repeatedly in the mode shown in FIG. 3 until the file content request is processed. In the above process, there are three very distinct characteristics. Firstly, limited by the system, the network request and the data response of the file are sequentially and serially carried out, and the file does not have the parallel capability; secondly, in a multi-session scene, due to the preemption of system resources by other sessions, the transmission efficiency under the current session is reduced; thirdly, due to the isolation of session levels in a multi-session scene, only the transmission channels of R1-S1 are utilized, and the transmission channels of other sessions cannot be effectively utilized. Both of these causes cause additional time consumption and reduce the remote transmission rate of the whole file content.
Referring to fig. 1, an embodiment of the present application provides a schematic flow chart of a method for transmitting desktop cloud data of a server, which may specifically include:
s110, receiving file transmission request information sent by a first local end;
for example, referring to fig. 4, when the server receives file transmission request information sent by the first local end, the file transmission request information may be triggered based on a paste operation instruction of a user, and a request file corresponding to the transmission request information is a target file selected by the user at the server and needing to be pasted.
S120, acquiring second local side information connected with the server side;
for example, after receiving the file transfer request information of the first local peer, the server obtains information of a second local peer that establishes a connection with the server, where the second local peer is a local peer that establishes a connection with the server except the first local peer, and as shown in fig. 4, 4 second local peers are included in total from the second local peer 1 to the second local peer 4.
S130, sending the second local side information to the first local side to enable the first local side and the second local side to establish local connection;
for example, the server transmits information of the second local peer connected to the server to the first local peer, where the information of the second local peer may include information such as an IP address of the second local peer. As shown in fig. 4, the second local end connected to the client has a second local end 1 to a second local end 4, and after receiving the information of the second local end, the first local end may apply for establishing a local connection with all or part of the second local end.
S140, transmitting a corresponding portion of the target file corresponding to the file transfer request information to the first local peer and the second local peer based on the file transfer request information, so that the first local peer obtains the complete target file from the server and the second local peer.
Illustratively, after the first local end and the second local end establish local connection, the first local end serves as a Master role of a file transfer task corresponding to the current file transfer request information, and the second local end serves as a slave role. The client can divide the file requested to be transmitted into different parts based on the file transmission request and send the different parts to the first local end and the second local end, and the second local end forwards the file to the first local end after receiving the transmission file sent by the server, so that parallel data transmission is realized.
As shown in fig. 5, a local transmission management module and a local connection module may be disposed in the Master local end, where the local transmission management module includes a file request management module, a Master-slave device connection module, and a temporary file segment management module, and correspondingly, the server end includes a remote desktop management module and a remote connection module. The Master-Slave device connection module is responsible for connecting and disconnecting Master and Slave role devices; idle conditions of the Slave device can be recorded; receiving a file segment transmission task and completing the transmission of the content of a certain file segment; and the temporary file management module is responsible for receiving and storing the file segment content transmitted by the remote PC as a temporary file. And the system is responsible for receiving other package content requests of the file request receiving module, reading the content of the specified package from the temporary file and returning the content to the file request receiving module. And also supports deletion of temporary files. And the application, registration and cancellation of the Master and the Slave roles are supported. And supporting the request of role list information, such as connection information of a plurality of Slave roles. And supporting the application processing of the Master connection Slave.
To sum up, in the desktop cloud data transmission method provided in the embodiment of the present application, a server sends, based on a file transmission request of a first client, information of a second local end connected to the server to a first local end, and after the first local end and the second local end are connected to each other, the transmitted files are respectively transmitted in segments to the first local end and the second local end which is locally connected to the first local end, and the second local end forwards the transmitted files to the first local end through local connection after receiving the transmitted files, so as to help the first local end to jointly complete a file transmission task. According to the method provided by the embodiment of the application, the local connection is established between the first local end and the second local end, and the file transmission is completed in parallel through the first local end and the second local end, so that the file transmission efficiency is improved, the transmission channels of a plurality of file segments are increased, and the file transmission stability is improved. The damage of one channel can be compensated by the transmission capability of other channels, and the utilization rate of the server is improved by borrowing the transmission capability of the conversation between other clients and the server.
In some examples, the sending the second local peer information to the first local peer to establish a local connection between the first local peer and the second local peer includes:
acquiring a first priority corresponding to the first local terminal;
acquiring a second priority corresponding to the second local terminal;
and controlling the first local terminal to establish local connection with the second local terminal under the condition that the first priority is higher than the second priority.
Illustratively, when receiving file transmission request information sent by a first local end, a server acquires a first priority of the first local end and a second priority of a second local end connected with the server, the server automatically judges the grades of the first priority and the second priority, and controls the second local end with the second priority smaller than the first priority to establish connection with the first local end, so that the second local end and the first local end complete a data transmission task together.
In summary, according to the desktop cloud data transmission method provided by the embodiment of the application, the server can automatically judge the priority between the local ends, and control the second local end with the priority lower than that of the first local end to automatically establish local connection with the first local end, so as to complete the file transmission task of the first local end together, and the method is convenient and fast.
