Referring to fig. 3, fig. 3 is a flowchart illustrating a data transmission method according to a first embodiment of the present invention.

In a first embodiment, the data transmission method comprises the steps of:

in step S10, a data packet sent by the first peripheral device through the external bus is received.

It should be noted that the execution main body of this embodiment is the first end device in fig. 2, where the first end device is a terminal device capable of processing and forwarding the received data packet.

It should be understood that the data packet may be a data packet generated by data that needs to be transmitted by the first peripheral device, and the first peripheral device transmits the data packet that needs to be transmitted to the first end device through an external bus, where the external bus is a communication path between the CPU and the RAM, the Read-Only Memory (ROM), and the input/output device interface, and in this embodiment, refers to a data transmission path between the first peripheral device and the first end device.

Step S20, obtaining ethernet data according to the data packet, where the ethernet data includes an identifier of an external bus API of the second end device.

In an embodiment, the parsing module 40 is further configured to parse the ethernet data to obtain the external bus data and a virtual bus data header; extracting the identification from a preset identification bit of the virtual bus data head; determining a corresponding connection type according to the virtual bus data head; and calling an external bus API corresponding to the identifier and the connection type, and sending the external bus data to second peripheral equipment by the external bus API.

In an embodiment, the invoking module 50 is further configured to obtain a plurality of API sets configured by the second end device; and selecting an external bus API from the API sets through the identification, and calling the external bus API.

Other embodiments or methods of implementing the data transmission apparatus of the present invention are described with reference to the above method embodiments, and are not intended to be exhaustive.

Further, it is to be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or system. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or system that comprises the element.

The above-mentioned serial numbers of the embodiments of the present invention are merely for description and do not represent the merits of the embodiments.

Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solution of the present invention or portions thereof that contribute to the prior art may be embodied in the form of a software product, where the computer software product is stored in a storage medium (e.g. Read Only Memory (ROM)/RAM, magnetic disk, optical disk), and includes several instructions for enabling a terminal device (e.g. a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.

The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
