  1. Test and Training Enabling Architecture (TENA) Gene Hudgins TENA Development Lead 4 March 2003 TheFoundationfor DoD Range Interoperability

  2. Foundation Initiative 2010Mission • Enable Interoperability among Range systems, Facilities, Simulations, C4ISR systems in a quick, cost-efficient manner, and • Foster Reuse for Range asset utilization and for future developments. Currently, range systems tend to be non-interoperable, “stove-pipe” systems. The purpose of TENA is to provide the architecture and the software implementation necessary to: • Support the Warfighter (Joint Vision 2010/2020) • Enable Simulation-Based Acquisition • Foster Test and Training Integration • In the long term: SAVE MONEY! Lay the Foundation for Future Test and Training Range Instrumentation

  3. Foundation Initiative 2010Project Objectives • Define a common Architecture for the test/training range community – called “TENA” (Test & Training Enabling Architecture) • Define a common Object Model to be used across the ranges • Define and build a common Software Middleware that will: • Use the object model • Enhance interoperability and reuse among the ranges • Common understanding of range processes – the Logical Range Concept of Operations • Define and prototype common Tools to configure and conduct multi-range, synthetic test events or training exercises • Create distributed, synthetic battlespaces with real weapon systems • Link multiple ranges together to form a larger, cohesive range • Enable testing, assessment, experimentation, and training of weapon system interoperability, C4ISR, and system-of-systems

  4. TENA was revised based on user feedback and lessons learned from working software prototypes TENA will be revised in the future based on future prototypes TENA is based on real-world tests at real ranges Test & Training Enabling Architecture(TENA) Prototypes User Feedback User Feedback User Feedback Prototypes Prototypes Prototypes Prototypes LessonsLearned LessonsLearned LessonsLearned Prototypes Overall Development Strategy

  5. Interoperability The characteristic of a suite of independently-developed components, applications, or systems that implies that they can work together, as part of some business process, to achieve the goals defined by a user or users. Reusability The characteristic of a given component, application, or system that implies that it can be used in arrangements, configurations, or in system-of-systems beyond those for which it was originally designed. Composability The ability to rapidly assemble, initialize, test, and execute a system from members of a pool of reusable, interoperable elements. Composability can occur at any scale — reusable components can be combined to create an application, reusable applications can be combined to create a system, and reusable systems can be combined to create asystem-of-systems. Driving Technical Requirements

  6. Interoperability requires: A common architecture An ability to meaningfully communicate A common language A common communication mechanism A physical connection between the two systems A common context A common understanding of the environment A common understanding of time A common technical process Reuse and Composability require the above, plus Well defined interfaces and functionalityfor the application to be reused TENA TENA Object Model (OM) TENA Middleware Network, shared memory TENA Object Model(Environment) TENA OM, TENA Middleware TENA Technical Process Reusable Tools,Repository Achieving Interoperability, Reuse, and Composability

  7. TENA Architecture Overview

  8. Ways TENA Middleware CanExchange Data • TENA presents to the range user a unification of several powerful inter-application communication paradigms • Publish/Subscribe • Similar in effect to HLA, DIS, or other PDU-based communication systems • Each application publishes certain types of information (the publication state) which can be subscribed to by any other application • Remote Method Invocation • Similar to CORBA or Java RMI • Each object that is published may have methods that can be remotely invoked by other applications • Messages • Individual messages that can be sent from one application to one or more other applications • Data Streams • Native support for audio, video, and telemetry

  9. Stateful Distributed Objects • An SDO is a combination of two powerful concepts: • a distributed object paradigm (like the one used in CORBA) • a distributed publish and subscribe paradigm. • Benefits of this combination: • A conventional distributed object-oriented system offers no direct support to the user for disseminating data from a single source to multiple destinations. • A conventional publish-subscribe system does not provide the abstraction of objects with a set of methods in their interface. • Interface to SDOs is a lot simpler and more usable than the combination of interfaces to their underlying technologies. • ANY APPLICATION can act as a server of some SDO objects and a client of other objects AT THE SAME TIME • TENA is a PEER-TO-PEER Architecture

  10. Logical RangeSimple Example TENA specifies an architecture for range resources participating in logical ranges Radar TestControl Station Simulation Communication Mechanism (Network, Shared Memory, etc.)

TENA Application A TENA Application C UserApplicationCode UserApplicationCode Proxy Servant Servant Servant Proxy Servant Servant Proxy TENA Middleware TENA Middleware TENA Application B UserApplicationCode Proxy Proxy Proxy Proxy Proxy TENA Middleware Logical RangeSimple Example • TENA specifies a peer-to-peer architecture for logical ranges • Applications can be both clients and servers simultaneously • In their role as servers, applications serve TENA objects called “servants” • In their role as clients, applications obtain “proxies,” representing other applications’ servants. Only servers can write to their servant objects’ publication state • The TENA Middleware, the TENA objects, and the user’s application code are compiled and linked together Radar TestControl Station Simulation Communication Mechanism (Network, Shared Memory, etc.)

  25. Key Elements of TENA Revisited • TENA lowers the cost to integrate systems together • Some systems made TENA-compliant <$20K for MC-02 • TENA decreases the time to integrate systems together • Auto-code generator generated 50K+ SLOC in a few hours from a 4 pg interface definition document • Legacy display system made TENA-compliant in 4.5 days for MC-02 • Hydrophone instrumentation system made TENA-complaint in 2 days • HLA-compliant display system gateway made TENA-complaint in 1 day • TENA lowers the cost to reuse systems in future events • Examples include VAST/IMPASS reusing pre-existing TENA capability • Will be better realized in future JNTC events • TENA improves flexibility of integrating systems together • Range applications can be optimally configured for the particular test event

  26. Key Elements of TENA Revisited (cont.) • TENA improves reliability of integrating systems together • Auto-code generator ensures that every system has same baseline of source code • Standard, validated algorithms (such as coordinate translations or unit conversions) can be embedded in TENA rather than burden software applications of managing and performing translations • TENA Middleware performs data marshalling/demarshalling rather than burden software applications • TENA eases Deployment at the DoD Ranges • TENA can be deployed gradually (system by system) rather than requiring all systems be redesigned • Providing on-site training at a number of ranges • TENA has a process to follow for sustainment/improvement • Leveraged CTTRA workshops and the Architecture Management Team (AMT) • Established on-line User Help Desk system to capture feedback from TENA users • Pursuing RCC standards, and investigating OMG standards • Working with T&E CTTRAP to determine TENA policy among Services
