A comparative study on packet by network design in in-ship

Lately, IT has been rapidly in land. as a result, mobile device come into wide use and is very important in everyday life. But in ship are limits network with communication Equipment and service. as a result, be far removed from information age. Currently, ship Is connected with the outside world via satellite on the voyage. but, because high billing, ship is possible data transfer using low speed bandwidth. because ship is not possible using LAN, only limit ship´s crew some use internet in limited space. so, ship is required construction of the network. in this paper, because composition of basic IT environment with information need of crew and customer from ship to cruises, there construct LAN in ship and propose network design for network of ship.
