Specifically, the optimal TS server may be not only one, but also multiple, and the scheduling rule may select the TS server with the largest weight or within a set weight range according to multiple factors such as an area where the TS server is located, network card capability, CPU occupancy rate, memory usage rate, and the like, according to the set weight.
And the applications APP of the intelligent network storage device 20 and the terminal device 30 establish connection with the corresponding optimal TS server according to the optimal TS server address, and the optimal TS server establishes a data transmission channel for the applications APP of the intelligent network storage device 20 and the terminal device 30.

Referring to fig. 2, fig. 2 is a data communication interaction diagram of an embodiment of the data transmission channel establishing system in fig. 1 for establishing a data transmission channel.
In the data communication interaction diagram, when a data transmission channel needs to be established, the terminal device APP sends a request for obtaining a TS server address to the control server, and meanwhile, the intelligent network storage device sends a request for obtaining the TS server address to the control server.
And the control server feeds back the optimal TS server address to the terminal equipment APP according to the scheduling rule and issues a session identification code to the terminal equipment APP, and meanwhile, the control server feeds back the optimal TS server address to the intelligent network storage equipment according to the scheduling rule and issues the same session identification code to the intelligent network storage equipment.
Specifically, the optimal TS server may be not only one, but also multiple, and the scheduling rule may select the TS server with the largest weight or within a set weight range according to multiple factors such as an area where the TS server is located, network card capability, CPU occupancy rate, memory usage rate, and the like, according to the set weight.
Further, the session identifier is a Unique encrypted key, the session identifier may be a UUID (universally Unique identifier)), the UUID is a globally Unique UUID allocated by the control server for the terminal device APP and the intelligent network storage device, the UUID is an identity identifier, and the terminal device APP and the intelligent network storage device can be matched by issuing the same UUID.
After the control server allocates the optimal TS server to the terminal device APP and the intelligent network storage device, the optimal TS server establishes a data transmission channel for the application program APP of the intelligent network storage device 20 and the terminal device 30, which specifically includes:
firstly, the intelligent network storage device and the terminal device APP establish TCP three-way handshake with the optimal TS server respectively. Specifically, connection is established through TCP three-way handshake, so that normal operation of subsequent communication interaction of the intelligent network storage device, the terminal device APP and the optimal TS server is guaranteed.
Then, the optimal TS server establishes mapping connection for the intelligent network storage device and the terminal device APP according to the allocation request of the intelligent network storage device and the terminal device APP, and specifically includes:

Specifically, the Universally Unique Identifier (UUID) has Unique identification information, and the allocation request includes the Universally Unique Identifier to ensure uniqueness of the allocation request and prevent confusion.
And step two, after receiving the distribution request, the optimal TS server distributes mapping ports for the intelligent network storage equipment and the terminal equipment APP, and stores the mapping ports in a Key-Value association structure. It should be noted that, after the intelligent network storage device and the terminal device APP are allocated with the mapping port, the establishment of the data transmission channel may be requested through the mapping port.
And step three, the terminal equipment APP sends a connection request to the optimal TS server, wherein the connection request comprises the session identification code, and the session identification code (UUID) is a globally unique UUID distributed by the control server for the terminal equipment APP and the intelligent network storage equipment.
Obviously, the current terminal device APP and the intelligent network storage device can be identified according to the session identifier (UUID).
And fourthly, the optimal TS server searches a port address of the mapping relation to be established in a Key-Value association structure, and initiates TCP connection of the intelligent network storage equipment and the terminal equipment APP to the mapping port, so that the mapping relation is established successfully. Obviously, the Key-Value association structure stores the mapping port.
Specifically, once the mapping port is determined, when data transmission occurs, TCP connection is performed through the port, and the TCP connection between the mapping port of the optimal TS server and the mapping port of the terminal device APP belongs to active connection, which requires the terminal device APP to send a request, and then the optimal TS server searches for a port address to be mapped in a Key-Value association structure, and then performs TCP connection of the mapping port.
And step five, the optimal TS server sends a connection response request to the terminal device APP, so that the mapping relation is successfully established, wherein the connection response request comprises a connection identification code attribute field. Specifically, the connection identification code attribute field is an attribute field which is allocated by the optimal TS server to the terminal device APP and is used for identifying request information, and provides an identifier for unique identification with the intelligent network storage device subsequently.
In this way, the optimal TS server successfully establishes mapping connection for the intelligent network storage device and the terminal device APP.
Finally, the optimal TS server establishes a data transmission channel for the intelligent network storage device and the terminal device APP according to the mapping connection relationship, and the communication process specifically includes the following steps:

And step two, the intelligent network storage device responds to the connection attempt request, establishes TCP three-way handshake connection with the terminal device APP through the optimal TS server according to the mapping connection relation, and establishes a data transmission channel, wherein after the intelligent network storage device is matched with the terminal device APP through the same connection identification code, virtual connection can be established through TCP three-way handshake, and the data transmission channel is established.
Therefore, the optimal TS server successfully establishes a data transmission channel for the intelligent network storage device and the terminal device APP.
After the data transmission channel is established, the data transmission process of the intelligent network storage device and the terminal device APP comprises the following steps:
the intelligent network storage device and the terminal device APP respectively send binding requests to the optimal TS server, and the binding requests include the connection identifier attribute field, which is obviously the same as the connection identifier attribute field allocated to the terminal device APP by the optimal TS server.
And the optimal TS server is bound with the data transmission channel according to the mapping connection to obtain a single data transmission channel for data communication of the intelligent network storage device and the terminal device APP. After the binding is successful, the data transmission channel can be used as a transfer channel, so that the intelligent network storage device and the terminal device APP finish data transmission under the assistance of the TS server.
After the intelligent network storage device and the terminal device APP are bound, data transmission can be completed under the assistance of the TS server on the premise that other request requirements do not need to be sent.
The data transmission channel establishing system provided by the embodiment of the invention selects the optimal TS server through the scheduling rule, and establishes the data transmission channel for the intelligent network storage device and the terminal device APP through the optimal TS server, so that the intelligent network storage device and the terminal device APP complete rapid data transmission through the data transmission channel and with the help of the TS server, the TS server performance is improved, the bandwidth is saved, and the memory loss is reduced.

In step S302, the intelligent network storage device and the terminal device APP establish a connection with a corresponding optimal TS server according to the optimal TS server address, and the optimal TS server establishes a data transmission channel for the intelligent network storage device and the terminal device APP.
Specifically, when a data transmission channel needs to be established, the terminal device APP sends a request for obtaining a TS server address to the control server, and meanwhile, the intelligent network storage device sends a request for obtaining a TS server address to the control server.
And the control server feeds back the optimal TS server address to the terminal equipment APP according to the scheduling rule and issues a session identification code to the terminal equipment APP, and meanwhile, the control server feeds back the optimal TS server address to the intelligent network storage equipment according to the scheduling rule and issues the same session identification code to the intelligent network storage equipment.

According to the data transmission channel establishing method provided by the embodiment of the invention, the optimal TS server is selected through the scheduling rule, and the data transmission channel is established for the intelligent network storage device and the terminal device APP through the optimal TS server, so that the intelligent network storage device and the terminal device APP complete rapid data transmission through the data transmission channel and with the help of the TS server, the TS server performance is improved, the bandwidth is saved, and the memory loss is reduced.

After the binding is successful, the data transmission channel can be used as a transfer channel, so that the intelligent network storage device and the terminal device APP finish data transmission under the assistance of the TS server.

Obviously, the Key-Value association structure stores the mapping port.
Specifically, once the mapping port is determined, when data transmission occurs, TCP connection is performed through the port, and the TCP connection between the mapping port of the optimal TS server and the mapping port of the terminal device APP belongs to active connection, which requires the terminal device APP to send a request, and then the optimal TS server searches for a port address to be mapped in a Key-Value association structure, and then performs TCP connection of the mapping port.
In step S505, the optimal TS server sends a connection response request to the terminal device APP, so that the mapping relationship is successfully established, where the connection response request includes a connection identity attribute field.
Specifically, the connection identification code attribute field is an attribute field which is allocated by the optimal TS server to the terminal device APP and is used for identifying request information, and provides an identifier for unique identification with the intelligent network storage device subsequently.
Referring to fig. 6, fig. 6 is a flowchart illustrating a fourth embodiment of a method for establishing a data transmission channel according to the present invention. Specifically, fig. 6 is a schematic flow chart illustrating that the optimal TS server in fig. 4 establishes a data transmission channel for the intelligent network storage device and the terminal device APP according to the mapping connection relationship.
At step S601, the optimal TS server sends an attempt connection request to the intelligent network storage device, wherein the attempt connection request includes the connection identifier attribute field. The connection identification code attribute field is the same as the connection identification code attribute field allocated to the terminal device APP by the optimal TS server, and the intelligent network storage device and the terminal device APP can be matched through the same connection identification code.
In step S602, the intelligent network storage device and the terminal device APP respectively send a TCP three-way handshake to establish a data transmission channel. After the intelligent network storage device is matched with the terminal device APP through the same connection identification code, virtual connection can be established through TCP three-way handshake, and a data transmission channel is established.
Preferably, the intelligent network storage device and the terminal device APP send binding requests to the optimal TS server, and the binding requests include the connection identifier attribute field, which is obviously the same as the connection identifier attribute field allocated to the terminal device APP by the optimal TS server.
And the optimal TS server is bound with the data transmission channel according to the mapping connection to obtain a single data transmission channel for data communication of the intelligent network storage device and the terminal device APP. After the binding is successful, the data transmission channel can be used as a transfer channel, so that the intelligent network storage device and the terminal device APP finish data transmission under the assistance of the TS server.
After the intelligent network storage device and the terminal device APP are bound, data transmission can be completed under the assistance of the TS server on the premise that other request requirements do not need to be sent.
According to the data transmission channel establishing method provided by the embodiment of the invention, the optimal TS server is selected through the scheduling rule, and the data transmission channel is established for the intelligent network storage device and the terminal device APP through the optimal TS server, so that the intelligent network storage device and the terminal device APP complete rapid data transmission through the data transmission channel and with the help of the TS server, the TS server performance is improved, the bandwidth is saved, and the memory loss is reduced.

The transmission module 706 is configured to perform data transmission with the terminal device through a data transmission channel established by the optimal TS server.
Further, referring to fig. 8, fig. 8 is a block diagram illustrating a sub-module of the connection module shown in fig. 7.
