Abstract : This thesis presents an architecture for ship-shore sea service communications. Starting with the ARPANET packet switching model (TCP/IP), Network and Logical Link layers are defined which deal with the following problems: (1) Many ship-shore links are one way only. A Network level acknowledgement protocol to work under TCP/IP, integrates multiple, heterogeneous, one-way links into a complete network; (2) Conventional network access procedures are invalid in HF ship-shore communications because the assumption that ships can hear each other transmit cannot be made. Two network access techniques are presented; (3) HF communications are characterized by low capacity and high noise. A Logical Link layer to manage these is presented. These three major topics are integrated into a complete system using the ISO reference model. The following is achieved: (1) A fully integrated system across all frequencies; (2) ARPANET/DDN interconnect capability; (3) Efficient, effective HF links.
