Thanks to CTOnews.com netizen rookie N number clue delivery! CTOnews.com July 26 news, according to the official letter software, they inherit the spirit of free and open source, combined with the current status of the operating system software and hardware industry chain, for the first time proposed the "layered classification" of the open source technology route, has achieved preliminary results, and has been applied to the letter UOS server version and the letter UOS cloud native version and other products.

CTOnews.com inquired about the official information of Tongxin and learned that the core idea of the "hierarchical classification" architecture mentioned here is "vertical layering, horizontal classification, data driving, algorithm first", which can structure the relationship of software packages and effectively "accelerate" system construction and maintenance.

The layered scheme is divided into layers according to the dependency relationship of software packages. Each layer defines its own functional scope and provides corresponding interfaces to the upper layer:

Kernel layer: Contains the operating system kernel and drivers, shielding hardware differences downward.

Core layer: The core software that is critical to the start-up and use of the operating system.

System layer: software that extends the kernel layer, core layer functions and services, and provides data and services to customers and applications.

Application layer: A variety of generic software for customers and applications (intersecting with various application scenarios).

The classification scheme is divided into three dimensions, namely, shape, function and scene:

Modality: According to the files in the software package and their description information, it is divided into libraries, tools and services.

Function: mainly according to the description information of the software package, excavate the function of it.

Scenarios: Based on the actual use scenarios of users, and according to the typical applications of these scenarios and their dependencies, merge them.

According to introduction, Tongxin UOS combines the "hierarchical classification" system with the BERT self-coding language model proposed by Google to calculate the relationship vector between each token and other tokens in each sentence, and then regularize the relationship vector to finally obtain the classification probability.

In short, the layering algorithm is based on the description information of the software package and the description information of its upper and lower dependencies. Classification algorithms classify software packages according to their description information.

According to the official, the unified UOS server version integrated into the "hierarchical classification" has five advantages: strong security, high stability, high performance, easy maintenance, and universal compatibility, which helps China's open source operating system compete on the world stage.
