The invention relates to a communication hierarchical architecture. The architecture comprises a real physical layer, a standard physical layer, a communication protocol layer, a communication application layer and a target application layer. The real physical layer is connected with the communication protocol layer through the standard physical layer; the communication protocol layer is connected with the target application layer through the communication application layer; the real physical layer is used for realizing a medium and a controller of data transmission and realizing transmission of a communication protocol; the standard physical layer is used for providing an interface of the real physical layer; the communication protocol layer is used for realizing verification, unpacking and packing of a data format and handshake of communication, and providing an interface between the communication application layer and the standard physical layer; the communication application layer is used for realizing analysis and packaging of a data function and providing an interface between the communication protocol layer and the target application layer; and the target application layer is used for realizing a target application. According to the invention, different real physical layers are supported, and the processing efficiency is improved.
Description
technical field [0001] The present invention relates to the communication field, in particular to a communication layered architecture. Background technique [0002] The OSI model, the Open Communication System Interconnection Reference Model, is a standard framework proposed by the International Organization for Standardization (ISO) that attempts to interconnect various computers into a network worldwide. The OSI model is divided into physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. In general embedded system applications, if you want to support different real physical layers, you must modify the functions of other layers; if you want to realize the support for different target applications, you must also modify the processing functions of other layers. This process is cumbersome and inefficient. [0003] Therefore, based on the above problems, it is urgent to provide a new layered architecture to s...
