4. Live Virtual Constructive Synthetic Environment
The acquisition, testing, training, analysis and experimentation communities require rapidly-composable, distributed LVC environments

5. The LVC Architecture Issue
Interoperability among LVC entities is essential. Current LVC environments, however, are not inherently interoperable. 
High Level Architecture (HLA) and Distributed Interactive Simulation (DIS) are most often used for integrating virtual and constructive assets,
Test & Training Enabling Architecture (TENA) is widely used in testing and to integrate live assets into exercises/events.
Also, Common Training Instrumentation Architecture (CTIA) leverages commonality among the U.S. Army's instrumented ranges and home stations; LVC - Integrated Architecture (LVC-IA) is a multi-echelon, integrated, joint, training and mission rehearsal environment; and others (e.g. ALSP)
Multiple protocols, gateways, and object models are often used to bring an LVC Environment together. 
Interoperability and efficiency issues arise bringing disparate protocols and entities together in a common operational environment.
Complexity, disconnects, duplication of effort, risk, and costs increase with multiple architectures.
Communities agree that we need to achieve efficient and effective interoperability.

7. Requirements Overview
Reduce the number of disparate interfaces
Support multiple, concurrent (a.k.a., many to many) translations
Support “plug and play” interface compatibility
Match or exceed current translation capability (throughput and functionality)
Support user extension through a public API
Free distribution with no licenses or proprietary components
Enable distributed monitoring, configuration, and control via a centralized, intuitive Graphical User Interface (GUI) to reduce operator requirements

8. Project Overview The JLVCDT is ….. The JLVCDT is not …..
The Services and the Joint community currently use multiple types, instances and implementations of LVC interfaces to support interoperability among disparate architectures and systems
Increases the total cost to conduct an event in the LVC environment
JLVCDT is designed to enhance the Joint training architecture and reduce overall costs by providing a certified framework and promoting interoperability and reuse of LVC interface components
The JLVCDT is …..
A system and software architecture
A framework for integrating protocol modules
An LVC integration tool
Currently a prototype
A platform for investigating future LVC integration concepts
The JLVCDT is not …..
A standard
A one size fits all solution
An attempt to make existing translation tools obsolete

9. JLVCDT Description
JLVCDT will improve Multi-Service LVC component interoperability
The effort will leverage Government-off-the-shelf (GOTS) and Commercial (non-proprietary) gateway applications
JLVCDT will deliver an open architecture via a public API to encourage broad adoption in existing LVC environments
JLVCDT and its plug-in modules will be JFCOM-certified in the Joint Advanced Training Technology Laboratory (JATTL)

10. Component Reuse Reuse existing components where possible and feasible
Where reuse saves time, reduces effort, furthers project goals
Consider reuse of data models, UIs, network communications, gateways
Realistic reuse for gateways includes
Network interface layer
Data packing/unpacking layer (becomes less feasible as the core architecture matures)

11. Architecture Overview
Core translates to/from a central data repository to accomplish multiple, concurrent translations efficiently
Common data definition
Defined architectural boundaries
Primary coding effort for a new data translation plug-in (reuse or custom) is the network interface layer and new data conversions
Examples will be available
Java-based core for efficiency
Large-scale object management
Multi-threaded processing
Uses Java Plug-in Framework (JPF)
Java and C++ bindings will be available

16. Current Performance
JATTL testing shows that JLVCDT performance compares favorably to the JNTC HLA/DIS gateway, which is viewed as a strong performing gateway
JLVCDT translates messages at the same rate (up to 4,000 HLA to DIS messages per second)
JLVCDT CPU usage is lower
JLVCDT memory usage is lower
JLVCDT can handle higher entity counts (i.e., higher than the JNTC HLA/DIS gateway’s maximum)
Should be able to collect performance data on how TENA plug-in compares to other TENA gateway applications (e.g., Goth) in the near future

Supported by the Joint community and the Services
Cost effective
A translator architecture that is:
Scalable – Based on hardware, software, and network performance requirements
Extensible – Can be easily adapted based on dynamic requirements and protocol specifications
Easy to configure and use – Comes with a distributed, intuitive Graphical User Interface that provides insight into hardware, software, and network configuration and performance 18
