|Network File Server (NFS)
High-Performance Onboard Connectivity on your Aircraft and Across your Fleet
Teledyne Controls' Network File Server (NFS), a key component of
Boeing’s Onboard Network System (ONS), functions as a stand-alone
server to provide a common, compact, non-essential, high-performance
onboard network solution. The NFS facilitates data transfer between
avionics systems and IP-based equipment, providing greater accessibility
to a wide range of applications. This high-reliability device, built to
OEM standards, combines the multiple functions of an ARINC 429 to Ethernet converter, multicast
router, firewall, data loader and communication gateway, in one single and lightweight unit. The
NFS can support a variety of applications, such as distribution and loading of software parts and
Electronic Flight Bag (EFB) operations. It facilitates high-capacity collection, distribution and storage
of important aircraft data for operations, maintenance and flight safety purposes. For expanded
networking capability, multiple NFS units can be connected together and/or interfaced with one or
several Teledyne Network Extension Device (NED).
Extensive Networking Functions
The NFS is designed to support extensive networking infrastructures. It interconnects previously
isolated onboard systems and sub-networks with various Ethernet wired interfaces, while enforcing
network security with its firewall functionality. The NFS acquires, processes, stores and distributes
data for multiple systems and applications. It can also manage Quality of Service (QoS), allowing
operators to prioritize traffic for critical applications.
Flexible Communication Gateway
Off board communication is also available through the NFS. The system can manage and interface
with a variety of communication systems and high-speed links to provide connectivity between the
airplane and the airline’s ground networks. For example, the NFS can connect to ACARS and Swift
Broadband SATCOM systems for in-flight communications, and interface with a wireless solution
such as Teledyne’s Wireless GroundLink® System (WGL) for ground-based connectivity.
ARINC 615-4 and ARINC 615A Data Loading
The NFS replaces the Airborne Data Loader functionality with full 615-4 and 615A data loading
capability. The NFS allows operators to streamline their data loading processes by eliminating the
need to reproduce, distribute and load countless floppy disks every month. The NFS provides file
storage and management services with an integral solid state drive. When using the NFS with
Teledyne’s WGL System and LoadStar® Server Enterprise (LSE) ground-based software, operators can
fully automate the electronic distribution and loading of software parts across their fleet.
Teledyne's NFS can host a range of existing applications, such as Engine Trim Balance, Weight and
Balance, Log Book and virtual QAR, to perform a variety of tasks for installed systems. The NFS also
provides a software framework that enables airlines to develop their own applications to access NFS
based features and services.
