Ship-shore packet switched communications system and an application in Hellenic Navy

Abstract

Computer to computer communications have advanced rapidly in the last years. High Frequency (HF) communications systems have not kept pace with these advances and have generally not been considered suitable for high speed data communications This thesis presents an architecture for ship-shore sea service communications. It starts with the problems that make sea service communications different from conventional systems (Local Area Networks, LANs). Then, these problems are intergrated into a comlete system by using the ISO reference model. The first three layers of the ISO reference model, physical, data link, and network layers are examined in reference to these problems. An examination concludes that a ship-shore packet switching communications system is applicable in Hellas and its Navy.
