System Support Layer

The system support layer provides functional support services for the dayu system, thus meeting the direct needs of users. Specifically, the system support layer consists of frontend server, backend server, and datasource server.

  • Frontend Server has built an interactive web-based frontend interface with VUE. After launching the dayu system, users can directly access the frontend page, and complete all operation processes through the buttons provided on the frontend page.

  • Backend Server is responsible for interacting with the frontend, building HTTP responsive services through Fastapi, providing real-time and specific responses for users' operations on the frontend page, including providing basic service data, installing functional components, and returning task execution result data, etc.

  • Datasource Server provides a simulated data source for users' stream data processing applications. In non-real simulation scenarios or test scenarios, the lack of a real-time stream datasource (such as a real camera) often leads to the system behavior and effects deviating from real scenarios. Therefore, in the dayu system, we build an optional datasource server to provide functions of various stream datasource generators including RTSP and HTTP, covering different types of datasources in real-world scenarios.
