One is to store a large amount of information generated by the station end as a temporary file and realize the transmission of the layer data of the process layer of the station end by using a file service. The disadvantage of this solution is that the file transmission process needs multiple interactions (including file generation, call notification, file opening, data transmission, file closing, file deletion, etc.), which is suitable for sending large data blocks, and the transmission efficiency is too low for frequently changing short data; the control on the granularity and the number of files is very complex, and a large number of files can be generated in practical application, so that the system performance is reduced, and the access delay is increased; the file format comprises redundant information such as a file header, a check code and the like, and the flow of network transmission is increased.
Another solution is to attach a proprietary contract to the model structure, for example, a group of Data Objects (DOs) needs to be used cooperatively to form a template, values between the DOs have relevance (for example, one represents Data identifier and one represents Data content), and when uploading information, all DOs in the template need to be set simultaneously and transmitted together. The scheme can avoid the problem of overlarge models, but the convention on the model structure is derived from some specific scenes, no standard can be followed, and the universality are lacked.
