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).
