As shown in fig. 1, in the client/server mode (C/S mode) of the prior art, if a host distributes a 30 Megabyte (MB) file to 3 nodes, the host needs to transmit the 30 megabyte file to each node, and the bottleneck of this transmission mode is the input/output performance (I/O performance) of the host, the upstream bandwidth, and the memory usage of multiple connections at the same time.

The appearance of Peer-to-Peer (P2P) technology allows users to directly connect to other users' computers for file sharing and exchange, realizes sharing data among users, has high transmission speed, and avoids the problem of client/server (C/S) mode. As shown in fig. 2, in the P2P mode, if a host distributes a 30 MB file to 3 nodes, the host may split the 30 MB file into 3 10MB file fragments, send the 3 file fragments to 3 nodes randomly, each node obtains a 10MB file fragment, and then the three nodes exchange data with each other, obtain the file fragments required by itself from other nodes, and finally obtain the complete file. The pressure of a server side can be reduced through P2P mode transmission, however, in an actual environment, the number of nodes is unpredictable, and problems that file fragments are segmented, one node is disconnected, and downloading of other nodes is influenced exist.

Therefore, it is desirable to provide a content transmission method and system, in which a slave node is controlled to obtain a content slice from a master node to a designated other node by dividing content into pieces of a fixed size, so that the method and system are suitable for a usage scenario in which the number of nodes is uncertain, and the influence of a node disconnection on the downloading of other nodes can be avoided, so as to establish a connection as required, reasonably and efficiently utilize a CPU and a memory, and improve transmission efficiency.

Fig. 4 is an exemplary flow diagram of a content transfer method provided in accordance with some embodiments of the present application. As shown in fig. 4, the process 200 may be implemented by the content delivery system 100. In some embodiments, the content delivery method 200 may be initiated automatically or by command. The instructions may include system instructions, device instructions, user instructions, action instructions, and the like, or a combination of the several.

At 201, content is acquired and sliced into fixed-byte slices by the master. Operation 201 may be implemented by the master 120 of the content delivery system 100. In some embodiments, the master 120 may obtain different content. The content may include, but is not limited to, scenes, cases, files, multimedia, and the like. By way of example, the scenes may include, but are not limited to, VR, AR, MR, XR scenes, either alone or in combination. The multimedia may include multimedia courseware, etc. In some embodiments, the master 120 may slice the content into fixed byte slices. The fixed byte slice may be byte sized by a configuration file, for example, 50 megabytes for a fixed byte.

At 202, the slices are randomly assigned to different slave end nodes. Operation 202 may be implemented by the master 120, the slave 130 of the content delivery system 100. In some embodiments, the master peer 120 may determine a slave peer node that is online in real time. In some embodiments, the master 120 may randomly assign the different slave nodes that slice the online. As an example, when the number of slices is less than the number of slave nodes online, the master 120 may assign the same slice to multiple slave nodes. For another example, the master 120 may assign at least one slice to a slave node when the number of slices is not less than the number of slave nodes on the line, and so on.

At 203, a content request sent from the slave is obtained. Operation 203 may be implemented by the master 120, the slave 130 of the content delivery system 100. In some embodiments, the master peer 120 may obtain the content request sent by the slave peer 130. In some embodiments, the slave 130 may request the master 120 for a slice, and the master 120 may obtain the slice request of the slave 130. As an example, when the slave 130 stores a partial slice of content, other slices of the content may be requested from the master 120.

At 204, slice information required by the slave is analyzed. Operation 204 may be implemented by the master 120 of the content delivery system 100. In some embodiments, the master peer 120 may analyze the slice information required by the slave peer 130 based on the content request. The slice information of the slave 130 may include all slices in which the content is sliced, slices that the slave 130 has stored are undesired slices, and slices that the slave 130 has not stored are desired slices. According to some embodiments of the present application, the flow 200 may omit operation 204 when the slave 130 directly requests the slice.

At 205, the slave is controlled to acquire slices to other designated slaves. Operation 205 may be implemented by the master 120 of the content delivery system 100. In some embodiments, the master 120 may control the slave 130 to acquire slices to a designated slave. As an example, based on the slice information, the master end 120 may determine the slave end node that stores the slice. And further, sorting the slave end nodes storing the slices according to the connection number of the nodes. The master 120 may determine the slave end node with the smallest number of connections as the designated slave end by the sorting. The master 120 may control the slave to acquire the slice to the designated slave.

In some embodiments, when slave end node A requests slice k of content (e.g., file X), master end 120 may determine other slave end nodes that store slice k of file X. When the slave B, E, F stores slice k in all three nodes, the master 120 or the server may sort the nodes currently storing slice k according to the number of connections, and the master 120 stores all slices as one node. Assuming that the number of connections of each node is as shown in table 1, the number of connections of the slave end node F is the smallest, and the master end 120 returns the information of the slave end node F to the slave end node a. To this end, slave end node a may send a file request (requesting slice k of file X) to slave end node F.

			E	3
F	1	√

According to some embodiments of the present application, the process 200 may further include obtaining, by the master or other slave, a desired slice, etc., when the designated slave is dropped. In some embodiments, the master 120 stores all slices of content, and when a given slave 130 is dropped, the desired slice may be retrieved by the master. As another example, when a designated slave 130 drops, the master 120 may reorder the on-line slave end nodes and designate the slice for the minimum number of connections slave end node.

It should be noted that, the master end and the slave end may be switched to each other, and any terminal receives the state of the sending request, and the terminal is defined to form the master end, and the terminal sending the sending request is defined to form the slave end.

As shown in fig. 5, the client of the intelligent platform 300 may include a teacher end (master end 120), a student end a (slave end 130), and a student end B (slave end 130). In some embodiments, the teacher end and the student end a may listen to a port, for example, the 10010 port. The student A can acquire the case list of the content, connect to the teacher end and send the case list. Further, the teacher end can update the case statistics list according to the case list sent by the student end A, and distribute cases to the student end. The student end A can request slicing from the teacher end, and the teacher end can calculate slicing nodes and feed back slicing request results to the student end A. According to the slicing request result, the student terminal A can request the student terminal B to download the slices, and the student terminal B can transmit the slices to the student terminal A. The student terminal A can inform the teacher terminal of the downloading progress in real time.
