Knowing the strengths and limitations of this architectural style, the development team is responsible to select the appropriate technologies which guarantee the consistency between the implementation and the design. This study proposes an evaluation framework which consists of a set of evaluation criteria that are architectural patterns recognized by the community and covering all the implementation aspects of software;and an evaluation function which combines these criteria for a given technology to determine its compatibility score with the microservice style, while taking into account the specific requirements of the software under development. Applying this approach to Spring Boot and JAVA EE technologies, we found that Spring Boot scores 96.3% while JAVA EE scores 44.4%. These scores reflect the effort required to conform software with the principles of this development style.展开更多

Existing emulation platforms struggle with challenges like the need for detailed implementation across all network layers, real-time response, and scalability. This paper proposes a digital twin system based on microservices for satellite Internet emulation,namely Plotinus,which aims to solve these problems. Plotinus features a modular design, allowing for easy replacement of the physical layer to emulate different aerial vehicles and analyze channel interference. It also enables replacing of path computation methods to simplify testing and deploying algorithms. In particular, Plotinus allows for real-time emulation with live network traffic,enhancing practical network models. The evaluation result shows Plotinus’s effective emulation of dynamic satellite networks with real-world devices. Its adaptability for various communication models and algorithm testing highlights Plotinus’s role as a vital tool for developing and analyzing SAGIN systems, offering a cross-layer,real-time,and scalable digital twin system.展开更多
