International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The F/A-18E/F Super Hornet fighter aircraft program is currently flight testing a Fibre Channel Network (FCN), which will initially replace certain Avionics Systems’ MIL-STD-1553 communications. The Advanced Mission Computers and Displays (AMC&D) and the Active Electronically Scanned Array (AESA) RADAR are replacing their MIL-STD-1553 counterparts to fulfill performance enhancements and growing data requirements. The maximum amount of data that can be transferred between these systems is significantly increasing. Each remote terminal on a MIL-STD-1553 bus can transmit or receive approximately 1Mbps. Each node on a FCN can simultaneously transmit and receive 1Gbps. With a Fibre Channel Network Switch (FCNS), multiple systems can communicate concurrently, thus increasing overall system throughput even further. Several other systems will be replaced in the near future utilizing the FCNS. The Fibre Channel Interface Unit (FCIU) was designed for the F/A-18E/F AESA program as a nonintrusive way to monitor multiple nodes, extract node specific information, and record this information using conventional on-board recorders. In order to reduce the risks associated with developing hardware and software concurrently with the Avionic System’s protocol, the FCIU was developed as an upper-level-protocol (ULP) (layer FC-4) independent device. Two big advantages of ULP independence are the avoidance of complex protocol programming for each different type of monitored network system and the non-intrusive nature of the FCIU connection to the FCN. This facilitates the quick installation of the FCIU to monitor any FC network and the FCIU IRIG-106 PCM type output lends itself to be integrated quickly into a typical Flight Test data recording or telemetry system.

International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / Since becoming an ANSI standard in 1994, Fibre Channel has matured into a high-speed reliable data communication solution. Fibre Channel uses point-to-point, arbitrated loop, or switched topologies, to provide a wide range of options for data storage and highspeed data transfer applications. Unlike Gigabit Ethernet, Fibre Channel supports protocols such as HIPPI-FP, SCSI and IPI, allowing for greater flexibility when designing systems. However, the wide range of options supported in the Fibre Channel standard can be the source of misunderstanding and incompatibility. This paper intends to clear up some of the misconceptions about Fibre Channel by presenting the current standard and discussing how Fibre Channel can be used in data acquisition systems. Since these systems often require extremely high throughput for routing data, as well as high speed data storage to long term media, solutions are not often cut and dry. This paper will give examples of how using different layers of the Fibre Channel protocol will meet the needs of today’s data acquisition requirements. It provides a brief overview of Fibre Channel technology and identifies the different types of Fibre Channel products available. It provides examples of how commercial-off-the-shelf (COTS) products can be used to build data acquisition and storage systems requiring throughputs of up to 90 Mbytes per second on a single fiber. Additionally, it shows how multiple fibers can be used to achieve much higher data rates.

International Telemetering Conference Proceedings / October 18-21, 2004 / Town & Country Resort, San Diego, California / More and more aircraft system designs are incorporating a local-area-network (LAN) using either Fibre Channel (FC) or Ethernet. To date there hasn’t been a means for creating a FC node connection between an airborne network and a ground based FC network or for creating a reliable high-speed Ethernet connection between air and ground. Ethernet connections have had some success by using the IEEE 802.11 wireless LAN for these types of connections; however, these connections suffer from many inherent problems using this standard. Problems include the lack of telemetry spectrum control, security validation, high-speed data transfer efficiency, and channel acquisition time. This paper will describe a methodology that utilizes the IRIG-106 PCM standard for communicating between aircraft and ground-based networks. PCM can solve the aforementioned problems and it enables the user to take advantage of the many ARTM advances in PCM telemetry technology [1]. One such advance in technology has been the use of SOQPSK (Tier 1) or Multi-h CPM (Tier 2) to enable the user to effectively double or more their bandwidth efficiency compared to PCM/FM (or CPFSK) (Tier 0).

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Modern aircraft now employ widely accepted and standardized technology commonly found in COTS applications. One such technology, Fibre Channel, has been deployed to transport both low and high-speed measurement data. Data as varied as “command and control”, “Radar Sensors” and “video” are being transmitted over fibre channel on many aircrafts. Some of these applications require data monitoring in listening mode only where transmission from the instrumentation equipment is not allowed or possible. As a result, standard off the shelf Fibre Channel devices cannot be used, and a development of a general purpose Fibre Channel monitor/ analyzer device and product is required. This paper discusses the concept, merits, and implementation of fibre channel bus monitoring in modern data acquisition systems. Techniques for tapping into an optical fibre channel network, as well as, a recording format for IRIG106 Chapter 10 are included. An overview of fibre channel topologies and protocols is also provided.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Gigabits and hundreds of megabit communication buses are starting to appear as the avionic buses of choice for new or upgraded airborne systems. This trend presents new challenges for instrumentation engineers in the areas of high speed data multiplexing, data recording, and data transmission of flight safety information. This paper describes the approach currently under development to acquire data from several types of high-speed avionic buses using distributed multiplexer and acquisition units. Additional input data may include PCM, wideband analog data, discrete, real-time video and others. The system is capable of multiplexing and recording all incoming data channels, while at the same time providing data selection down to the parameter level from input channels for transmission of flight safety information. Additionally, an extensive set of data capture trigger/filter/truncation mechanisms are supported.

The networks in traditional data centers have remained unchanged for decades and have grown large, complex and costly. Many data centers have a general purpose Ethernet network and one or more additional specialized networks for storage or high performance low latency applications. Network convergence promises to lower the cost and complexity of the data center network by virtualizing the different networks onto a single wire. There is little evidence, aside from vendors' claims, that validate network convergence actually achieves these goals. This work defines a framework for creating a series of unbiased tests to validate converged technologies and compare them to traditional configurations. A case study involving two different network converged technologies was developed to validate the defined methodology and framework. The study also shows that these two technologies do indeed perform similarly to non-virtualized network, reduce costs, cabling, power consumption and are easy to operate.

International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A traditional Front-end Processor (FEP) with local RAID storage can limit the operational throughput of a high-rate telemetry ground station. The Front-end processor must perform pass processing (frame synchronization, decoding, routing, and storage), post-pass processing (level-zero processing), and tape archiving. A typical fifteen minute high-rate satellite pass can produce data files of 10 to 20 GB. The FEP may require up to 2 hours to perform the post-pass processing and tape archiving functions for these size files. During this time, it is not available to support real-time pass operations. Honeywell faced this problem in the design of the data management system for the DataLynx ä* ground stations. Avtec Systems, Inc. and Honeywell worked together to develop a data management system that utilizes a Storage Area Network (SAN) in conjunction with multiple High-speed Front-end Processors (HSFEP) for Pass Processing (PFEP), multiple HSFEPs for Post-pass Processing (PPFEP), and a dedicated Tape Archive server. A SAN consists of a high-capacity, high-bandwidth shared RAID that is connected to multiple nodes using 1 Gbps Fibre Channel interfaces. All of the HSFEPs as well as the Tape Archive server have direct access to the shared RAID via a Fibre Channel network. The SAN supports simultaneous read/write transfers between the nodes at aggregate rates up to 120 Mbytes/sec. With the Storage Area Network approach, the High-Speed Front-end Processors can quickly transfer the data captured during a pass to the shared RAID for post-processing and tape archiving so that they are available to support another satellite pass. This paper will discuss the architecture of the Storage Area Network and how it optimizes ground station data management in a high-rate environment.
