The concept of $k$-shortest disjoint paths is considered important because the establishment of primary and backup forwarding paths exploiting shorter distance and faster propagation time is a dominant consideration for the design of a survivable backbone network. Therefore, we need to evaluate how well the concept of $k$-shortest disjoint paths is exploited for the design of a survivable ship backbone network considering the international standard related to ship backbone networks, the IEC61162-410 standard specifying how to manage redundant message transmissions among ship devices. Performance evaluations are conducted in terms of following objective goals: link capacity, hop and distance of primary and backup paths, even distribution of traffic flows, restoration time of backup forwarding paths, and physical network topology connectivity.

This paper proposes a design of a ship backbone network-based on the survival and efficiency of the ship network. Currently IEC operates the standard ship network, a standard specification "IEC 61162-410 maintains the operation of the network. IEC 61162-410 offers a high stability of the ship network by using terminal equipment. But current studies are incomplete because it has been assumed that the ship's network will operate at double its current capacity. This paper analyzes the double ship backbone topology for an organization and then will summarise the minimum costs required to implement the ship backbone topology using an ILP. Also, we present an effective traffic assignment technique that uses an ILP, metaheuristic, heuristic algorism-based underlying the ship backbone network. The results by experimenting the design of the network confirmed a greter efficiency, stability and cost-effectiveness of the ship network.

선박에서 사용되는 네트워크 장치를 통합하여 통신 인프라를 구축하고 이를 운용 및 제어 하는 기술 SAN(SAN : Ship Area Network ) 은 국내외 조선 산업계 동향에 따라 그 필요성이 점차 높아지고 있다. 이에 본 논문 에서는 선박 통신 인프라를 운용 및 제어하는 데이터 통신 프로토콜 체계를 정의한 표준 IEC-61162-410 을 분석 하고 표준 관련 사항들을 기반으로 선박 네트워크 장치를 실시간 관리 하고 선박 네트워크 시스템간의 통신을 제어 및 관리 하여 안전하고 신뢰성 있는 데이터 전송을 제공 하는 프로토콜 기법을 제안 하였다.
