Internet Protocol Address (Internet Protocol Address), often abbreviated as IP (Internet Protocol) Address, is a digital label assigned to an Internet Protocol device used by a user to access the Internet, and the IP Address can be generally divided into: a public network IP address and a private network IP address.

Please refer to fig. 2, which is a schematic diagram illustrating a file transmission method according to an embodiment of the present application; the file transmission method is applied to the server, and can comprise the following steps:
step S210: and the server receives the unique identification of the storage device sent by the terminal device.
Unique Identification (ID), also called unique identifier, refers to an identification symbol capable of uniquely identifying a target, where the unique identification is, for example: a Media Access Control (MAC) address of the storage device, a hard disk serial number of the storage device, a Windows product identification number of the storage device, a machine guid or a motherboard smBIOSUUID, and so on.
The embodiment of step S210 described above is, for example: the server receives the unique identifier of the storage device sent by the terminal device through a Transmission Control Protocol (TCP) or a User Datagram Protocol (UDP); wherein, the TCP protocol is also called network communication protocol, which is a connection-oriented, reliable and byte stream-based transport layer communication protocol; in the Internet protocol suite (Internet protocol suite), the TCP layer is an intermediate layer located above the IP layer and below the application layer; reliable, pipe-like connections are often required between the application layers of different hosts, but the IP layer does not provide such a flow mechanism, but rather provides unreliable packet switching. The UDP Protocol is a short for User Datagram Protocol, a Chinese name is a User Datagram Protocol, and the UDP Protocol is a connectionless transport layer Protocol in an Open System Interconnection (OSI) reference model, and provides a transaction-oriented simple unreliable information transfer service.
Step S220: and the server determines tunnel indication information corresponding to the unique identifier of the storage device.
The tunnel indication information is storage index information indicating a data tunnel, where the data tunnel is a virtual tunnel established between a source device and a destination device on a physical network by using a Tunneling Protocol (Tunneling Protocol), and the source device and the destination device may perform secure communication and data transmission through the virtual tunnel. The tunneling protocol is a network protocol in which a different network protocol is encapsulated in a payload portion using one network protocol; the reason for using tunnels is to transport data over incompatible networks or to provide a secure path over an unsecured network. Common tunneling protocols are for example: SSH Protocol, Point-to-Point Protocol (PPP), or Point-to-Point Protocol Over Ethernet (PPPoE). The above tunnel indication information includes, for example: index information of a network socket established using the SSH protocol, the PPP protocol, or the PPPoE protocol, and the like.
The above-mentioned embodiment of determining the tunnel indication information corresponding to the unique identifier of the storage device in step S220 may include the following steps:
step S221: and the server judges whether the indication information of the data tunnel corresponding to the unique identifier of the storage equipment is found in the cache.
The above embodiment of step S221 is divided into the following two cases:
in the first case, the cache is a local cache; the local cache may be a memory database or a cache database, for example: memcached and Redis, etc.; random Access Memory (RAM) of the server, etc.; then, in this case, the implementation manner of step S221 is, for example: if the Redis service is installed on the server, whether indication information of a data tunnel corresponding to the unique identifier of the storage device exists or not can be inquired by using the Redis service on the server; if the data tunnel exists, finding the indication information of the data tunnel corresponding to the unique identifier of the storage equipment in the cache; if the unique identifier does not exist, the indication information of the data tunnel corresponding to the unique identifier of the storage device is not found in the cache.
In the second case, the cache is an external cache; the external cache may be a cache device in communication with the server, where the cache device refers to a device capable of providing a cache service for the server, and specifically, the cache device may be, for example, a device installed with a Memcached service, or a device installed with a Redis service, and the like; then, in this case, the implementation manner of step S221 is, for example: if the cache device is a device of Redis service, the server may send the unique identifier of the storage device to the cache device; the cache device searches the indication information of the data tunnel corresponding to the unique identifier of the storage device according to the unique identifier of the storage device and sends a search result to the server; the server receives a search result sent by the cache device; if the searching result is found, searching the indication information of the data tunnel corresponding to the unique identifier of the storage equipment in the cache; and if the searching result is that the data tunnel corresponding to the unique identifier of the storage device is not found, the indication information of the data tunnel corresponding to the unique identifier of the storage device is not found in the cache.
Step S222: and if the indication information of the data tunnel corresponding to the unique identifier of the storage device is found in the cache, the server determines the indication information as tunnel indication information.
The embodiment of step S222 described above includes, for example: the index information of the network socket corresponding to the unique identifier of the storage device is queried by using the Redis service on the server, and then the index information of the network socket can be determined as the indication information of the data tunnel corresponding to the unique identifier of the storage device. In the implementation process, the data tunnel corresponding to the unique identifier of the storage device is hit by using the cache, and the data tunnel is taken out from the cache, so that the connection between the data tunnel and the storage device can be quickly established by using the data tunnel, and the efficiency of file transmission between the terminal device and different storage devices is effectively improved.
Step S223: if the data tunnel corresponding to the unique identifier of the storage device is not found in the cache, the server establishes the data tunnel of the storage device according to the unique identifier of the storage device, and determines the indication information for establishing the data tunnel of the storage device as tunnel indication information.
The embodiment of step S223 described above is, for example: if the index information of the network socket corresponding to the unique identifier of the storage device is not inquired by using the Redis service on the server, the server inquires the storage device corresponding to the unique identifier of the storage device in the relational database, establishes the network socket of the data tunnel with the storage device, and determines the index information of the network socket as tunnel indication information. In the implementation process, if the data tunnel corresponding to the unique identifier of the storage device is not found in the cache, the data tunnel of the storage device is established according to the unique identifier of the storage device, and the indication information for establishing the data tunnel of the storage device is determined as tunnel indication information; that is to say, when the data tunnel is not searched in the cache, the server establishes the data tunnel, thereby effectively improving the establishing and using efficiency of the data tunnel.
The above-mentioned embodiment of establishing the data tunnel of the storage device according to the unique identifier of the storage device in step S223 includes:
step S2231: and the server determines the gateway equipment according to the unique identifier of the storage equipment, wherein the network segment to which the network address of the gateway equipment belongs is the same as the network segment to which the network address of the storage equipment belongs.
The above-mentioned implementation manner of step S2231 is, for example, that the server queries a relational database for a storage device corresponding to the unique identifier of the storage device, where the relational database refers to a database that organizes data by using a relational model, the relational database stores data in the form of rows and columns for the user to understand, the series of rows and columns of the relational database are called as a table, and common relational databases are, for example, Mysql, PostgreSQ L, Oracle, SQ L server, and the like.
Step S2232: the server establishes a data tunnel between the server and the gateway device, and the network segment to which the network address of the server belongs is different from the network segment to which the network address of the gateway device belongs.
