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).
