Interface-independent virtual Ethernet communication component and method for realizing communication

Abstract

The invention discloses a virtual Ethernet communication component irrelevant to an interface and a method thereof for realizing communication, and relates to the technical field of communications. The communication component comprises a physical interface used for providing a physical channel to receive and send data, a physical interface driving module and a virtual Ethernet device driving module. Wherein, the physical interface driving module is used for controlling the physical interface to receive and send data according to a physical interface bus protocol; the virtual Ethernet device driving module is used for registering as a virtual Ethernet device in a Linux kernel; and in a data receiving and sending process, the data interaction with an upper layer network protocol stack and the physical interface driving module is realized by an Ethernet interface virtualized by the virtual Ethernet device. According to the virtual Ethernet communication component disclosed by the invention, the virtual Ethernet interface is used as an intermediate bridge to connect the upper layer network protocol stack and the physical interface, so that an upper layer can communicate by the network protocol stack of the Linux kernel, and no communication protocol needs to be singly designed, therefore the development difficulty is reduced, and the reusability of development codes is high.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a virtual Ethernet communication component irrelevant to an interface and a method for realizing communication thereof. Background technique [0002] With the gradual development of communication technology, the processing capacity and data transmission capacity of network equipment are getting higher and higher, and various communication interfaces emerge in an endless stream, such as: I2C (Inter-Integrated Circuit, microcontroller and peripheral connection interface), SPI (Serial Peripheral Interface, Serial Peripheral Interface), UART (Universal Asynchronous Receiver / Transmitter, Universal Asynchronous Receiver Transmitter Interface), Ethernet (Ethernet Interface), PCIe (PCIExpress Interface), etc. [0003] When realizing communication between devices, due to the different configurations of each communication interface, developers need to develop corresponding applicatio...

Problems solved by technology

In this way, it not only makes the development difficult, the cycle time is long, and the maintainability is poor. Moreover, when the device needs to upgrade a single disk or upgrade the communication interface, the previous code cannot be reused, and the code needs to be redeveloped, which is time-consuming and laborious.
