This document describes the requirements involved in ship to shore data communication between the shipboard data servers and the on-shore data servers. It provides information on:

— asynchronous communication;
— a method to measure end-to-end communication quality;
— transport integrity;
— transport security (e.g. encryption, authentication and authorization);
— management of data transmission (e.g. prioritization, logging, carrier awareness/management);
— communication optimization (e.g. deduplication, compression, resume, multiplexing);
— compliance with the data communication protocols, including but not limited to ISO 19847.

This document does not cover:

— the security of the data producer/consumer (e.g. identity management);
— communication equipment requirements;
— carrier performance requirements (e.g. bandwidth and latency).
