–Combined SST and TmNS Data Flows
–Summary
5/9/2011 40ITEA Workshop 2011
Applications
• Lossless Telemetry– SST Backfill – retrieve lost SST data from recorder
– TmNS Backfill – retrieve lost TmNS data from recorder
– TmNS Direct – lossless data direct to ground
• Remote Control of Instrumentation System– Reconfigure Instrumentation
– Recorder Control (start / stop)
• Efficient Spectrum Utilization– Dynamic Spectrum Allocation
– SST Transmitter Reconfiguration (power and frequency)
• TmNS provides a bidirectional network to support these and other capabilities
5/9/2011 41ITEA Workshop 2011
TmNS Technical Definitions
• TmNS: Telemetry Network System
• TmNS Data Message– A “container” for holding and transporting data
• measurement data, bus data, etc.
• End Node– A network device that produces and/or consumes TmNS Data Messages
• Network Device– A device that merely propagates TmNS Data Messages (i.e. router, switch, etc.)
– Neither produces nor consumes TmNS Data Messages
• Network Recorder– An End Node that records TmNS Data Messages and can replay TmNS Data
Messages back on demand
• Network Gateway– An End Node that provides a bidirectional data gateway between the TmNS and
a PCM system
5/9/2011 42ITEA Workshop 2011
TmNS Network Protocols
• For network transport of TmNS Data Messages, the
TmNS uses the Internet Protocol (IP) Suite
• TmNS uses two data transport protocols:
– Transmission Control Protocol (TCP)
– User Datagram Protocol (UDP)
• TmNS Data Messages are encapsulated in either TCP
packets or UDP datagrams and then encapsulated into
IP packets

Reliability Critical (RC)
Data Delivery Protocol• Reliability Critical (RC) Data Delivery Protocol
– TmNS Data Messages transported via TCP
• TCP Pros:
– Reliable delivery
• retransmits lost packets
– Ensures proper ordered data delivery
– “Robust” protocol
• TCP Cons:
– Non-deterministic data latency
• due to retransmission of packets
– “Robust” protocol
• requires network overhead
5/9/2011 44ITEA Workshop 2011
Latency/Throughput Critical (LTC)
Data Delivery Protocol• Latency/Throughput Critical (LTC) Data Delivery
Protocol– TmNS Data Messages transported via UDP
• UDP Cons:– Data delivery not guaranteed
• packets can be dropped
– Data can arrive out of order• TmNS messages have sequence numbers
• UDP Pros:– Relatively low, deterministic data latency
– Efficient multiple consumer support• Able to utilize multicast delivery
– “Simplistic” protocol• less network overhead than TCP
– Controlling network configuration increases reliability
5/9/2011 45ITEA Workshop 2011
Example: Classification of TmNS Data Flows
• LTC Data Delivery Data Flows
– LTC-AQ
• Data originates directly from an acquisition source
– LTC-NAQ
• Data does not originate directly from an acquisition source
– (ex: simulation data recorder retrieved data)
• RC Data Delivery Data Flows
– RC-DR
• Data Retrieval, retrieval of recorded TmNS Data Messages
– RC-NRT
• Near Real Time, lossless transmission of acquired data

Function of System Management
• Designed to simplify the operation of large networks; this includes:– controls strategic assets from a central position
– aids in strategically planning for network growth
– provides remote system management
– operates independently of the system it monitors
– supports multiple protocols
– operates as transparently as possible

consists of:
– a manager (s)
• the central controller
– the managed device
• network devices like routers and gateways which
interconnect sub-networks

Spectrum Management
Outline
–Overview of spectrum allocation issues
–Network and Spectral parameters
5/9/2011 73ITEA Workshop 2011
Spectrum Resource Challenges
• Diminishing availability of spectrum for TM
– Reassignment to other uses
– Increasing number of “competitors” for available spectrum
– More simultaneous units under test
• Demands of new telemetric networks
– Dynamic bandwidth allocation
– Dynamic sharing of spectrum between aircraft
– Dynamic quality of service (QOS) assignments
– Additional control parameters
• It’s a hostile environment!
– Once working, wired networks tend to continue to work
– Fixed wireless networks can be fine-tuned
5/9/2011 74ITEA Workshop 2011
What is Spectrum Resource Management?
• Provides interfaces to the user for status, configuration, and control of the available spectrum bandwidth
• Status– Link state, utilization, data rates, dropped packets,
errors, network topology, connected nodes, etc.
• Configuration– Link speed, routing, IP address, service setup,
firmware load, etc.
• Control– Enable/disable, reset, etc.

Spectrum Management Complications
• Consider Radio Access Network– TDMA parameters
• Slot time
• Slot allocation
• Frame gaps and guard times
– Modulation• Waveform
• Symbol rate
• Center frequency
– Power control• How far am I from my Hub?
– Antenna control• Where am I pointing in relationship to the test article?
5/9/2011 77ITEA Workshop 2011
Other Considerations
• Spectrum use must be coordinated among test articles
• Spectrum use must be coordinated among test ranges
– Range to Range handoff
– Ranges with spectral overlap
• QoS requirements of a test article are dynamic based on
data telemetry requirements
• Spectrum needs of a test article depend on its QoS
requirements
• Status monitoring of Spectrum resource parameters
required to determine system health and provide
feedback for control
5/9/2011 78ITEA Workshop 2011
Spectrum Management Approach
• Complexity and interdependence of spectrum
management parameters requires a centralized control
component
• Some aspects (e.g. slot allocation) may have response
time requirements that may require localized control
components
• Spectrum management depends on QoS and bandwidth
requirements of data sources
– Requires tight coupling between Network and Spectrum
management
• Exact mechanisms will be worked out on the Range.
5/9/2011 79ITEA Workshop 2011
Spectrum Management Summary
• Spectrum management driven by spectrum
allocation issues and new demands of
networked telemetry
• New systems have a number of parameters to
control
– TDMA, Modulation, Power, Antenna
• Interrelation of NM and SM parameters require a
close coupling of the two systems
5/9/2011 80ITEA Workshop 2011
Metadata
Outline
–For telemetric networks
–Components of metadata
5/9/2011 81ITEA Workshop 2011
Metadata for
Telemetric Networks• What is Metadata?
– Information that describes a test system from multiple aspects
– Describe test requirements
– Describe the design of a test system
– Describe the configuration of the test system• instrumentation, telemetry, network equipment, etc.
– Describe how test data is formatted, encapsulated, and stored
• What language is Metadata?– Most modern forms use XML and a schema definition
– A common metadata language is useful in the case that people, tools, hardware, and software applications will exchange information about a test
• without a common language for describing the test, interoperability between the elements in a test system is not likely
• What is a common Metadata common language?– Defines a common set of terms, concepts, and rules for which metadata descriptions are
created• basically an agreement in which how to exchange information
• XML schema is an example
• What Metadata is not?– Not a language for capturing measurement data
– Large part is describing the test configuration documented in a configuration file(s)
5/9/2011 82ITEA Workshop 2011
Metadata for
Telemetric Networks (2)• How is Metadata used?
– Metadata describing the configuration information in a common
language and documented in a standard file structure will:
• Allow a system manager application to configure the networks and
devices for basic network interoperability
• Metadata will be consumed by the end nodes (instrumentation and
telemetry devices) to configure the network interfaces for the test
– Metadata will describe the network data formats to ground
system application that will extract measurements from data
flows, or otherwise consume test data flows
– Metadata will describe the system management polices and
potentially the mapping between the system management
standard interfaces and the actual device specific interfaces
5/9/2011 83ITEA Workshop 2011
Metadata for
Telemetric Networks (3)
• Why is Metadata important to iNET?
– A common metadata language is crucial to iNET because of the
many users, hardware developers, and application developers
need a common language for exchanging information about the
test.
• Without a common language, users, vendors, and integrators will
develop their own disjointed and specialized files for storing test
setup and device configuration information.
– The lack of a standard metadata language will allow the past
practice of stovepipe designs to continue to proliferate, will limit
competition between vendors and application providers, and will
keep upward pressure on integration cost for tests.
5/9/2011 84ITEA Workshop 2011
Main Components of Metadata
• Language Standard
– The letters, words and some rules for forming
sentences
– Language modeling is a balance of generality for
extensibility and specificity for simplicity.
– Documented as a model, schema, and language
guide
• Instance Documents
– The books written in the language
– May adhere to additional rules (constraints)

System Integration and Testing
High Level
5/9/2011 195ITEA Workshop 2011
System Testing Approach
• Overall approach documented and guided by System Test Plan
• Organized into three major overlapping phases– Test Plan Authoring
– Test Setup
– Test Implementation
• Utilize iNET System Integration Lab (iSIL) at SwRI
• Develop System Management and Metadata framework for distribution– Provides baseline representation of system standards
• Reuse test tools developed by teams, reference applications, and simulators– Provides baseline representation of standards
– Provides example software to community
• Work closely with teams– Provide test plans to teams before testing
– Cooperative testing among teams
– Provide constructive feedback to teams to speed resolution of issues
5/9/2011 196ITEA Workshop 2011
System Integration and Test Approach
• Integrate components from subsystems into an
overall system
– RF Network, Range Network, TA Network, MCR Network
• Provide lab testing of system
• Validate system is ready for
– Developmental Flight Test
– Advanced Flight Test
• Build increasing fidelity of system
– Use software simulators and COTS initially
– Replace with prototypes as they become available
– Three sub-spirals of capability
5/9/2011 197ITEA Workshop 2011
iSIL Approach
• Build up representative configurations– Currently have some test article hardware
• Focus on end-to-end control and data flow
• Utilize existing flight hardware where possible– Switches, adapt EndNodes with Proxies
• Utilize COTS hardware as needed until prototypes are available– Switches, routers, general PCs as device simulators
• Augment network size and loading with simulators
• Measure throughput, latency, timing accuracy, jitter, network link utilization, and data loss

Mission Control and Range Operations
Test and Integration• Test & Integration labs at both Edwards & Pax in work
• Mix of iNET and Range investment
• Primary purpose: full capabilities to support flight tests
• Initial uses: component and sub-system integration– Reduces risk for flight test, and system integration at iSIL
• Edwards (MCS / IADS)
• Dedicated System at antenna site, B4795
• May loop back thru range network to add ground test fidelity
• Pax (RTPS Vista 550 / IADS)
• Shared System at main RTPS site, B2118 (iNETprimary user)
• Potential to schedule some operational range assets– Example: TA recorder (or sim) at antenna site accessed via
range network from MCR iNET lab at B2118.

RF Network
Test and Integration• Support development of
RF Subsystem – Reference Implementations
– Technology Demonstrators
– Advanced Prototypes
• Support unit and subsystem test of – Radios / IR2
– LM, RFNM, RFNO
• Support RF Subsystem Integration prior to System Integration at iSIL
General purpose laptops used to support varied reconfigurations based on specific test/integration needs
5/9/2011 201ITEA Workshop 2011
TA Network
Test and Integration• Build four representative test
articles in iSIL at SwRI– Simulators initially – replace with
hardware and software as it becomes available
• Utilize COTS hardware as needed until all flight hardware available– Switches, routers, general PCs as
device simulators
• Augment network size and loading with simulators
• Add capabilities as planned in spirals– Follow test plans to validate new
capabilities with regression testing for risk items
