Unified data communication software architecture adapted to various communication links

Abstract

The invention relates to a unified data communication software architecture adapted to various communication links. The unified data communication software frame comprises three layers, namely, a transmission layer, a network layer, and a link layer, and the structure of each layer is divided into an external interface layer, an internal plug-in layer, and a concrete realization layer. Each internal plug-in layer is used for classified packaging of various technology implementation details provided by the corresponding concrete realization layer according to different mechanisms or ways. Each external interface layer is used to package the functions after the classified packaging of the corresponding internal plug-in layer according to the different mechanisms or ways into a unified way. The software frame is advantageous in that after hierarchical division, architecture design, and software abstract, the interface provided for users is simple and unified, and at the same time, the layer is clear; upper use and developers are not required to concern about various communication technology concrete details, and only by invoking three layers and eight interfaces (or even only six interfaces), the data communication of the various communication links is simply and conveniently completed.

Description

technical field [0001] The invention relates to a unified data communication software framework adapted to various communication links. Background technique [0002] With the development of communication technology and embedded technology, more and more communication technologies are applied to various embedded devices (such as mobile phones, various POS terminals, etc.) Purpose of Data Transfer. At the same time, on the same device terminal (such as POS in the financial industry), it is common to support multiple communication methods at the same time, such as the traditional 802.3 Ethernet method, asynchronous modem, and various wide-area communication technologies (such as, 2G GPRS or CDMA, 3G TD or WCDMA, 4G communication technology, etc.), wifi (802.11b / g / n, etc.), BlueTooth, etc. (Note: Simple communication methods, such as serial port communication, often only involve reading and writing, etc. Simple actions, they do not have to use the method proposed in the presen...

Problems solved by technology

In the JAVA-based system (such as Android system), although the actions before the socket connection are simplified, after the connection and before the data interaction, these actions are added to map the IO flow used for the subsequent data interaction from the socket resource, so , still cumbersome
