All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a file transmission system based on an intelligent integrated identifier network, as shown in fig. 1, the system includes: the terminal node requesting file downloading, the terminal node with the file to be downloaded and a seed file storage server, wherein the seed file storage server stores a plurality of seed files; a terminal node requesting file downloading acquires a seed file stored by a seed file storage server, determines a terminal node with a file to be downloaded according to analysis of the seed file, and initiates a file transmission request to the terminal node with the file to be downloaded according to mapping from a service identifier to a connection identifier by adopting a plurality of transmission paths; receiving a part of file transmitted to each transmission path by a terminal node with a file to be downloaded; and synthesizing the partial files transmitted by all the transmission paths to obtain the required complete file.

The system introduces an intelligent identification scheme, and each service and connection in the network are endowed with a unique identification, so that the whole network becomes a whole capable of carrying out information sharing, and the concept of identification and mapping is introduced, thereby solving the problem that an IP address in the traditional network represents both the position and the identity of a terminal, realizing the controllable management of the network and providing good support for multi-path transmission and mobility.
In an embodiment, the file transmission system based on the intelligent converged identity network adopts a network architecture shown in fig. 2, that is, a terminal node requesting file downloading and a terminal node having a file to be downloaded may be in the same network or not, and when the terminal node requesting file downloading is not in the same network, the terminal node requesting file downloading is first connected to an Access Router (AR) of the same network through a line, then completes communication with other Access networks through a Core Router (CR) in a Core network, and finally connects to the terminal node having the file to be downloaded.
Specifically, the terminal node requesting file downloading and the terminal node having the file to be downloaded are both provided with SID and CID identifications, and simultaneously are provided with a plurality of network interfaces for data transmission, or comprise at least two network interface cards. In addition, distributed multipath Transmission client software is also deployed on the terminal node requesting file downloading and the terminal node having the file to be downloaded, multipath Transmission of the distributed multipath Transmission client software is based on an MPTCP (Multi Path Transmission Control protocol) protocol, the data file is divided into links, data is sent at the same time, an intelligent identification scheme is introduced, and unique identification is given to each service and connection in the network, so that the whole network becomes a whole capable of carrying out information sharing. Wherein each service requirement of the end node can be represented by a unique SID.
In an embodiment, the terminal node having the file to be downloaded is configured to generate a seed file according to the file to be downloaded, and upload the seed file to the seed file storage server to broadcast the file information, where the seed file includes description information of the file to be downloaded; the terminal node with the file to be downloaded is also used for responding to file transmission requests of a plurality of transmission paths, dividing the file to be downloaded into a plurality of shares according to the MPTCP transmission protocol and respectively transmitting the shares to the transmission paths.
Specifically, the MPTCP protocol transmission diagram is shown in fig. 3. The TCP sub-stream layer is responsible for communicating with the network layer, so that the sub-stream of the MPTCP has the same characteristics with the traditional TCP data stream on the network layer, the path establishment and transmission of the sub-stream layer are the same as the traditional TCP, and the difference is that the MPTCP can establish a plurality of sub-streams. MPTCP can be compatible with network application programs using TCP, multipath parallel transmission can be carried out, the network throughput is improved, and in the transmission process, a terminal node containing a file to be downloaded distributes the file to each available link for data transmission after splitting the file through a connection control layer, namely the purpose of multipath transmission is achieved.
Specifically, the terminal node having the file to be downloaded constitutes a file fragment storage server, that is, the file to be downloaded that the terminal node has is a fragment file, so that when the seed file is acquired from the seed file storage server, it can be determined whether the seed file is a part of the required complete file from the description information included in the seed file, for example, the required complete file is a, the description information may be represented as a-3-1, which indicates that the required complete file is divided into three parts, the found seed file is the first part, and then, the seed files having the description information of a-3-2 and a-3-3 may be searched.

After all the seed files of the required complete file are found, such as the seed files with the description information of A-3-1, A-3-2 and A-3-3, the found seed files can be analyzed to determine the terminal nodes generating the corresponding seed files, namely the terminal nodes with the fragment files to be downloaded can be determined.
In an embodiment, when the terminal node requesting the file download obtains the required complete file, the seed file may also be generated according to the required complete file, and the generated seed file is uploaded to the seed file storage server. Thus, the terminal node requesting the file download may also be a terminal node having a file to be downloaded. In addition, because the file to be downloaded included in the terminal node requesting the file downloading is a complete file, the terminal node requesting the file downloading can only communicate with the terminal node to acquire the file. In addition, when the terminal node requesting for file downloading does not acquire a complete file, for example, only one fragmented file is acquired, a seed file may be generated according to the acquired file and uploaded to the seed file storage server.
The file transmission system based on the intelligent integrated identification network provided by the embodiment of the invention not only splits the file into a plurality of independent transmission paths for transmission, increases the file transmission efficiency, but also increases the difficulty of information stealing to a certain extent, and improves the data security. Meanwhile, each fragment of a complete file is stored in different terminal nodes for downloading, and distributed data storage is realized on a service level, so that the terminal nodes can complete file providing and acquiring.
The embodiment of the invention provides a file transmission method based on an intelligent integrated identification network, which comprises the following steps as shown in figure 4:
step S101: and acquiring the seed file stored by the seed file storage server.
In an embodiment, first, a terminal node having a file to be downloaded may generate a seed file according to the file to be downloaded, and upload the seed file to a seed file storage server to broadcast file information. When the seed file is generated, the seed file not only can contain corresponding terminal node information based on the information of the file to be downloaded, but also can be used for other terminal nodes to find the terminal node. Then, when the terminal node requesting the file download needs to acquire the file, the corresponding seed file may be acquired from the seed file storage server.
In one embodiment, the seed file includes description information of the file to be downloaded. The file to be downloaded which the terminal node has is a fragmented file, so when the seed file is acquired from the seed file storage server, whether the seed file is a part of the required complete file or not can be determined from the description information contained in the seed file, for example, the required complete file is a, the description information can be represented as a-3-1, it indicates that the required complete file is divided into three parts, the found seed file is the first part, and then the seed files with the description information of a-3-2 and a-3-3 can be searched. In addition, the description information may also be expressed in other manners, which is not limited in the embodiment of the present invention.
Step S102: determining a terminal node with a file to be downloaded according to the analysis of the seed file; specifically, after the terminal node requesting for downloading the file finds all corresponding seed files according to the required complete file, the obtained seed files are analyzed, and the terminal node corresponding to the generated seed files can be determined. For example, if three seed files are found, three corresponding terminal nodes having files to be downloaded can be obtained by analyzing the three seed files, and the files to be downloaded in each terminal node are a part of the complete file.
Step S103: and adopting a plurality of transmission paths, and initiating a file transmission request to the terminal node with the file to be downloaded according to the mapping from the service identifier to the connection identifier.
In one embodiment, after determining the terminal nodes having the corresponding files to be downloaded, a connection may be established with each terminal node through a plurality of transmission paths. Specifically, after both nodes establish a connection on one path (e.g., between eth0 network cards), the party initiating the connection also sends a packet to inquire whether other paths can transmit. If yes, the opposite end (the terminal node with the corresponding file to be downloaded) responds, and then the transmission relation is established in the second path according to the establishing mode of the first path. Therefore, a plurality of transmission paths are established between the terminal node requesting the file downloading and each terminal node with the corresponding file to be downloaded so as to realize parallel transmission. When distributed multi-path parallel transmission is carried out, a terminal node requesting file downloading generates a corresponding SID identifier according to required file information, and after the mapping of SID and CID is completed through multi-path transmission, the nodes are combined with bottom layer hardware equipment to realize communication with an opposite terminal.
In an embodiment, when a connection is established between a terminal node requesting file downloading and a terminal node having a file to be downloaded, it is required to determine whether the terminal node and the terminal node having the file to be downloaded are in the same network; when the terminal nodes are not in the same network, the terminal nodes requesting file downloading are firstly connected with Access Routers (ARs) of the same network through lines, then the communication with other Access networks is completed through Core Routers (CR) in the Core network, and finally the terminal nodes are connected to the terminal nodes with files to be downloaded.
Step S104: receiving a part of file transmitted to each transmission path by a terminal node with a file to be downloaded; specifically, after a connection is established between a terminal node requesting file downloading and a terminal node having a file to be downloaded, the terminal node having the file to be downloaded responds to file transmission requests of multiple transmission paths, and splits the file to be downloaded into multiple parts according to an MPTCP transmission protocol, and transmits the multiple parts to the transmission paths respectively. For example, when three transmission paths are established between two terminal nodes, the terminal node may divide the file to be downloaded into three parts, and transmit the three parts to the node requesting the file download through the three transmission paths.
In an embodiment, during the file transmission, an acknowledgement mechanism may be further established between the two terminal nodes, that is, after receiving the data block, any end needs to reply an acknowledgement signal to ensure reliable integrity of the data and notify the peer end point of the interval of the received data block. After the data is sent, the connection can be disconnected only after the two parties jointly confirm the connection closing. And in the data transmission process, the two terminal nodes also simultaneously send the local real-time state to the distributed seed file storage server.
Step S105: and synthesizing the partial files transmitted by each transmission path to obtain the required complete file.
In an embodiment, the terminal node requesting the file download synthesizes all the files after receiving them, and then obtains the required complete file. For example, when the description information of the seed file determines that the required complete file fragment is stored in three terminal nodes, the connection can be respectively established with the three terminal nodes; meanwhile, when the connection is established, three transmission paths are formed between the terminal node and each terminal node, the terminal node requesting for file downloading can acquire partial files from nine transmission paths, and the acquired nine partial files are synthesized to obtain the required complete file.
In an embodiment, when the terminal node requesting the file download obtains the required complete file, the seed file may also be generated according to the required complete file, and the generated seed file is uploaded to the seed file storage server. Thus, the terminal node requesting the file download may also be a terminal node having a file to be downloaded. In addition, because the file to be downloaded included in the terminal node requesting the file downloading is a complete file, the terminal node requesting the file downloading can only communicate with the terminal node to acquire the file. In addition, when the terminal node requesting for file downloading does not acquire a complete file, for example, only one fragmented file is acquired, a seed file may be generated according to the acquired file and uploaded to the seed file storage server.
The file transmission method based on the intelligent integrated identification network provided by the embodiment of the invention adopts a multi-path parallel transmission mode, namely, when a plurality of available paths exist in the network, each path is comprehensively utilized for data transmission, the difficulty of information stealing is increased to a certain extent, and the network security and the transmission rate are improved.

Meanwhile, each fragment of a complete file is stored in different terminal nodes for downloading, and distributed data storage is realized on a service level, so that the terminal nodes can complete file providing and acquiring.

In an embodiment, as shown in fig. 6, in the process of file transmission, a terminal node having a file to be downloaded, that is, a distributed node, performs parameter check, and exits if the terminal node fails; after the parameter check is successful, the terminal node with the file to be downloaded judges whether to manufacture a meta-information file, namely a seed file, according to the requirement; then the terminal node initializes the monitoring socket, if the terminal node fails, the terminal node prompts that the initialization of the monitoring socket fails and quits; after the initialization monitoring socket is successful, the terminal node initializes the connection with the seed file storage server, and if the initialization fails, the initialization fails and quits; after the initialization is successfully connected with the seed file storage server, the terminal node starts to transmit data through circulation; and after the data transmission is finished, the terminal node exits the cycle and writes the data in the buffer area into the hard disk, and then the transmission is finished.
