Problems solved by technology

[0005] The first way, because the protocol layer in the host protocol stack needs to be modified, so there is a problem of difficulty in deployment; the second way, because the identification and address separation is implemented on a specific application, it cannot meet the backward requirements of the application. compatibility

Embodiment 1

[0090] The embodiment of the present invention provides a method for data transmission. In the method, an identifier layer is established between the application layer and the transport layer in the terminal protocol stack to realize the separation of the IP address and the identifier. Among them, the schematic diagram of the terminal protocol stack is as follows figure 1 as shown, figure 1 Among them, the identifier layer provides a new API (Application Programming Interface, application programming interface) to the application layer App, so that the application layer can initiate a session based on the identifiers of the communication parties, and the identifier layer maintains the session and maps the identifiers For the corresponding IP address, thereby establishing and managing the connection of the transport layer, so that the transport layer still transmits data based on the IP address. based on figure 1 As shown in the terminal protocol stack, this embodiment takes ...

Embodiment 2

[0125] This embodiment of the present invention provides a data transmission method. For the convenience of description, this embodiment combines the content of the first embodiment above and figure 1 The schematic diagram of the protocol stack shown is for data transmission between the terminal A with the identifier layer laid out and the terminal B with the identifier layer laid out, and the identifier of terminal A is identifier A, and the IP address of terminal A is address A , the identifier of terminal B is identifier B, and the IP address of terminal B is address B as an example to describe the data transmission method provided in this embodiment. Before describing the method provided by this embodiment, first combine figure 1 The shown protocol stack describes the identifier layer in the protocol stack. The identifier layer provides the following functions in order to realize the mapping from identifiers to IP addresses, and to establish and manage connections in the ...

Embodiment 3

[0168] This embodiment of the present invention provides a data transmission method. For the convenience of description, this embodiment combines the content of the first embodiment above and figure 1 As shown in the schematic diagram of the protocol stack, terminal A deploys the identifier layer, terminal B' does not deploy the identifier layer, terminal A establishes an identifier-based connection with the agent node that deploys the identifier layer, that is, terminal C, and A transport layer connection such as TCP (Transmission Control Protocol, Transmission Control Protocol) or UDP (User Datagram Protocol, User Datagram Protocol) is established between terminal C and terminal B', and the connection between terminal A and terminal B' is realized through terminal C. Taking data transmission as an example, the method for data transmission provided by the embodiment of the present invention is illustrated. Wherein, the identifier corresponding to the proxy node terminal C is ...

Abstract

The present invention relates to the technical field of network communications. Disclosed are a data transmission method, terminal and system, the method comprising: a first terminal invokes a local identifier layer interface via a local application layer to transmit data to a second terminal corresponding to a second identifier; mapping the second identifier to a second internet protocol (IP) address corresponding to the second terminal via a local identifier layer, and invoking a local transport layer interface to transmit the data to the second terminal corresponding to the second IP address. The present invention establishes an identifier layer between an application layer and a transport layer, utilizes the application layer to invoke an identifier layer interface, completes the mapping from an identifier to an IP address via the identifier layer, and invokes a transport layer interface to realize identifier-based data transmission between two communication ends, thus requiring no modification to an original protocol layer in a protocol stack of a terminal, and addressing the issues of difficult deployment and backward compatibility.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a data transmission method, terminal and system. Background technique [0002] With the continuous development of network communication technology, data transmission has attracted more and more attention because of its fast and convenient characteristics. In the process of data transmission, using the identification and address separation mechanism to realize the transmission of network data is a hot issue in the current Internet technology research. [0003] In the existing technology, there are two main ways to realize data transmission by using the identification and address separation mechanism: the first way is to realize the transport layer identification by creating a new module under the transport layer of the host or by adding or modifying the transport layer protocol The mapping of ID to IP (Internet Protocol, Internet Protocol) address of the int...
