Journal of Marine Science and Technology
Many automatic systems developed for the merchant ships are focused on the Unmanned Machinery Space (UMS), and therefore it is necessary to build a local area network (LAN) on the ship in order to integrate these automatic systems. By means of the Inmarsat satellite system, the shipboard LAN is interconnected with the terrestrial communication networks such as the Internet. In the paper, the shipboard LAN is designed from the view point of survivability, and three concepts to reduce the satellite communication cost for the interconnection of the shipboard LAN and the Internet are proposed. Finally, the way to implement the …
