Net- Enabled Test Environment (NETE)

  • Concept

    • Virtual Test environment – no new facility

    • Industry and Government participation

    • Experimental approach – test, measure, evaluate, adjust

    • Adopting existing projects; leveraging progress

  • Benefits

    • Data sets made available will bring interested developers

    • Allows demonstration of concepts to flesh out requirements

    • Allows trade-off studies for architectural decisions – standards, processes, TTPs, tools, infrastructure design

    • Tests Governance model for efficacy

    • Accessible to all NextGen participants; can link to outside data sources/consumers

    • Leverages work already done by NextGen Stakeholders

NETE Accomplishments To-date

  • Inter-agency Collaboration Framework

  • Inter-agency Infrastructure Modeling

  • Network Connectivity Verification (Demo 0)

  • NETE Governance

    • Draft Information Sharing Agreements

    • Collaboration Tools

    • Baseline Security Profile

Nete infrastructure modeling

NETE Infrastructure Modeling

  • Rich Set of metrics and measures collected in NETE Simulation Model

  • Enables performance analysis, study of alternatives etc.

  • Message exchange pattern traces to enable Information service “playback”

Multi layered model design

Multi-layered Model Design

  • Network Scenarios capturing interconnection between NETE Agencies

  • Intra Agency Site models abstracting real-world agency network/service architecture based on interactions with ESC, NASA and FAA

  • Custom models of SOA-capable devices from application to physical layers



  • Build on the Foundation of Interagency Collaborations

    • NETE Working Group as a forum for addressing governance issues

    • On-going NETE infrastructure modeling initiative to provide a snapshot of the interagency network and SOA infrastructures

    • Participating from agencies critical to success of NETE

  • Support Effective Information Sharing and Engagements of Community of Interests (COI)

    • JPDO is engaging with NextGen weather and integrated surveillance community to identify information exchanges

    • NETE supports information sharing goals by providing a platform for exploration, experimentation, and socialization of information exchange services

  • Facilitate 1 Year Challenge Demonstration

    • Incremental approach progressing with participation with select demos

    • Serve as a risk reduction environment for summer demonstrations

Opportunities continued

NETE Demonstration Objectives

  • Demonstrate the NCOD’s approach to secure and effective information sharing by leveraging Semantic Web Service Architecture (SWSA)

    • Exercise information exchanges developed in collaboration with Integrated Surveillance community

    • Demonstrate ontology-driven approach to enhance service discoverability and interoperability

    • Elaborate key infrastructure components (e.g. Semantic Service Registry) of SWSA

  • Demonstrate NETE as a platform for inter-agency demonstrations

    • Showcase the ability to execute distributed demonstration involving multiple agencies

    • Refine process to facilitate future NETE demonstrations

  • Serve as a risk reduction environment for JPDO summer demonstrations

    • Improve confidence on the Lost Cargo Jet business scenario

Planned NETE Demonstrations


  • Communication Validation Demonstration (Demo 0) prepares NETE as the platform for Information Exchange Demonstrations

    • Establish connectivity among initial NETE nodes

    • Verify ability to share information through web services

    • Initiate discussions on security and business relationships

  • Information Exchange Demonstration (Demo 1) establishes the software and service framework for Information Exchange Demonstrations

    • Exercise information exchanges related to integrated surveillance

    • Demonstrate key components of the semantic web service infrastructure (e.g. Semantic Service Registry)

      • Information Exchange Demonstration (Demo 2) focuses on reducing risks for JPDO 1 Year challenge demonstration

    • Exercise information exchanges related to integrated surveillance
