Beschreibung
Zusammenfassung:	In an edge computing system which includes a data distribution service (DDS) including a DDS client in the edge area, a DDS gateway in the edge server, and a database in the cloud, the DDS Client installed in the edge area enables edge applications installed in the edge area to communicate with the DDS, a DDS interface is provided between the DDS client and the edge application using interface definition language (IDL) and inter-process communication (IPC), and the edge DDS client and the edge server gateway form a unified modeling language (UML) structure. Accordingly, the present invention can make a DDS lightweight and compatible with edge equipment with insufficient computing resources. 엣지 영역의 DDS 클라이언트(Client), 엣지 서버의 DDS 게이트웨이(Gateway) 및 클라우드의 데이터베이스(Database)를 구비하는 데이터 분산 서비스(DDS)를 포함하는 엣지 컴퓨팅 시스템에 있어서, 엣지 영역에 설치되는 상기 DDS 클라이언트(Client)는 엣지 영역에 설치되는 엣지 애플리케이션이 DDS(Data Distribution Service) 통신을 가능하게 함에 있어서, DDS 클라이언트(Client)와 엣지 애플리케이션 간에는 IDL(Interface Definition Language)와 IPC(Inter-Process Communication)을 활용하여 DDS(Data Distribution Service) 인터페이스를 제공하고, 엣지 DDS 클라이언트(Client)와 엣지 서버의 게이트웨이(Gateway)는 UML(Unified Modeling Language) 구조를 이루는 것을 특징으로 한다.
