NETWORK SERVER SYSTEM (NSS)
|Publication Date:||31 August 2005|
Purpose and Scope
This document describes a typical Network Server System (NSS) for installation in all types of aircraft. It defines the physical form factors and fit dimensions. It defines the electrical interface definition and typical system functions.
The NSS description includes a common file server, data processing, mass storage and interface capabilities to a number of terminals connected via an onboard aircraft Local Area Network (LAN).
It is the intention of the airlines to apply popular and commercially available components (Commercial Off-The-Shelf (COTS) components) for the file server and the transceiver devices. These units may be repackaged for aircraft installation.
The NSS is a central node through which terminals are able to communicate with avionics systems, access data and applications stored in the NSS mass memory storage. The NSS may be configured to provide off-aircraft communications via multiple data links including high-speed wireless ground communications with a ground-based information system.
The NSS may be used to complement some of the functions of a Communications Management Unit (CMU) and may provide non-flight critical aircraft communications.
