Description
Recently, communications speed of several tens Mbps and flat-rate service have been available as radio links. Although, it is especially difficult to maintain the connected state from ships by using them. The purpose of the paper is that the authors construct the stable Internet connection by efficiently utilizing them for ship to shore. There has been literature on aspects of data collection system to understand marine traffic data from ship and shore. We examined by a simulation built at Toba Maritime College and applied the results to Training Ship TAISEIMARU (Length 125m, 5,887 Gross tons). The following are the results obtained: By limiting of number of NAT (Network Address Translation) descriptor, it reduced the occupancy rate of the line to approximately one-seventh, so that a median of Round Trip Time improved approximately 100ms. Moreover, we established the unattended network connection automatic changeover system by using Virtual Router Redundancy Protocol for ship and shore.
