Abstract

Trend of next generation satellite communication network is distribution and enlargement of network structure with increased network terminals, and traffic which use satellite communication is increasing and frequently occurring. Under specific satellite communication environment that various communication device dynamically forms a network domain and frequently exchanges the data, data-centric publish/subscribe data exchange is more suitable than server/client data exchange. So, this paper analyze DDS performance for application of DDS standard to distribution network management system which aims to efficiently manage limited satellite resource, and also this paper covers comparative study on DDS and SNMP(server/client data exchange). Study compares DDS and SNMP using OPNET, and result of study is analyzed from a network layer performance perspective.

차기 위성의 통신망은 단말의 수가 증가하고 네트워크의 구조가 분산화 및 대형화되고 있는 추세이며, 위성 통신을 이용하는 트래픽이 증가하고 빈번하게 발생하고 있다. 위성 통신과 같이 다양한 통신 장비들이 동적으로 도메인을 형성하고 데이터를 빈번하게 주고받는 통신 환경에서는 서버/클라이언트 방식의 데이터 교환보다는 데이터 중심 발간/구독 방식의 데이터 교환이 더욱 효과적이다. 따라서 본 논문에서는 한정된 위성 자원을 효율적으로 관리하기 위한 분산 망관리시스템에 데이터 중심 발간/구독 통신 기술인 DDS 표준을 적용하기 위하여 DDS의 성능을 분석하였으며, 기존의 서버/클라이언트 방식으로 데이터를 교환하는 SNMP와 비교 연구하였다. 비교 연구를 위해 OPNET을 사용하였으며 네트워크 계층 관점의 성능 중심으로 수행하였다.
