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.

Application Hosting
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.
