  1. Link-16 Enhanced Throughput Internet Protocol/Bandwidth-on-Demand(Link-16 ET IP/BoD)Pete Camanapete.camana@viasat.com

  2. Topics • Concept for IP over Link-16 • Proposed Demonstration Program • Increased Throughput with ET • Bandwidth on Demand • Transition Plan and MIDS Retrofit

  3. Concept of Link-16 Today 2.4 KBPS Voice Stacked Nets NPG 12 (Voice A) JTIDS Or MIDS Terminal Voice A 16 KBPS Voice Stacked Nets NPG 13 (Voice B) Voice Voice B NPGs 1-4 Entry, Time and Net Mgmt MS-1553 NPGs 5, 6, 14 & 27 PPLI and Status or Stanag -3910 NPG 7 Surveillance TADIL-J NPG 8 Mission Management NPG 9 Air Control or X.25 NPG ….

  5. Joint PMW-101/159 and PMS-454 Demonstration Program • LCDR Matt LeTourneau (PMW-101/159) will Present Details Thursday • Applications over Link-16 IP: • PMS-454 Joint Fires Network (JFN) China Lake Tactical Dissemination Module (TDM) Strike Package Collaboration (Push-Pull) • REDS NSAWC Strike Package Collaboration (Push-Pull) • EPLRS Situation Awareness (Pull) • Three Phase Program to Demonstrate IP over Link-16 in Tactically Significant Scenario • Link-16 Interoperability Testing in SPAWAR System Integration Facility • Application Interoperability at TDM and F/A-18 Labs at China Lake • Flight Interoperability with F/A-18 at China Lake

  6. Program Team • NAVSEA PMS-454 for the Joint Fires Network (JFN) • Naval Air Warfare Center Weapons Division for the Tactical Dissemination Module (TDM) Application • SPAWAR Systems Center for Real-time Execution Decision Support (REDS) System and EPLRS Applications • SPAWAR PMW-101/159 for the Communications • DRS Systems for the Applications/Communications Integration and Contracting • ViaSat for the IP over Link-16

  7. First Step Demonstration (all 3 phases)(Funded) • Tunnel IP Packets Through Link-16 MIDS LVT • Plan is to use J16.0 message • Network will use "stolen" Voice network • Selection is performed by Net Number Selection (say Net #47) • User gives up Voice B (for Example) for IP Connectivity • Single Net Number used and IP is Broadcast • Use both 112 and 224 Slot Voice Networks for Demos • Plan to use P4SP as Baseline • Use of Enhanced Throughput to compare performance

  8. Concept of IP over Link-16 Basic Demo User Selects to get IP, giving up Voice B, with selection of Voice B to Net # 47 Link-16 Terminal IP Net # 47 P4SP~16 KBPS Ethernet IP 2.4 KBPS Voice Stacked Nets NPG 12 Voice A 16 KBPS Voice Stacked Nets NPG 13 X Voice Voice B NPGs 1-4 Entry, Time and Net Mgmt MS-1553 NPGs 5, 6, 14 & 27 PPLI and Status or Stanag -3910 NPG 7 Surveillance TADIL-J NPG 8 Mission Management or X.25 NPG 9 Air Control NPG ….

  9. Concept of IP over Link-16 ET Demo User Selects to get IP at ET rates with selection of Voice B to Net # 48, 49… Link-16 Terminal IP Net # 48 ET ~120 KBPS Ethernet IP 2.4 KBPS Voice Stacked Nets NPG 12 Voice A 16 KBPS Voice Stacked Nets NPG 13 X Voice Voice B NPGs 1-4 Entry, Time and Net Mgmt MS-1553 NPGs 5, 6, 14 & 27 PPLI and Status or Stanag -3910 NPG 7 Surveillance TADIL-J NPG 8 Mission Management or X.25 NPG 9 Air Control NPG ….

  10. ET Network Rates

  11. Next Step Bandwidth-on-Demand (BoD) • Assign Multiple Net Numbers to IP traffic • IP Packet Connectivity is Connection Oriented • Transition from Broadcast to Connection by Net Number • Multi-Net Number- Multi-Rate TDMA Control • Potentially Include Proxies to aggregate data for forwarding • Use Orderwire Slots for User Network Access • Identify Packet Connections Needed and Negotiate Net Number • Identify Capacity Needs and Agree on Repetition Rates • Initially demonstration would again be in Voice B Stacked Nets • Also would use one terminal as network controller • Finally Transition to new NPG and Distributed Network Control of IP Traffic

  12. Concept of IP over Link-16 Next Unfunded Growth Step Demo Link-16 Terminal Orderwire Slots Assign Net & Slots IP Stacked Nets Negotiated Rates Ethernet IP Nets 63-126 Net 0-62 2.4 KBPS Voice Stacked Nets NPG 12 Voice A Voice Voice B 16 KBPS Voice Stacked Nets NPG 13 NPGs 1-4 Entry, Time and Net Mgmt MS-1553 NPGs 5, 6, 14 & 27 PPLI and Status or Stanag -3910 NPG 7 Surveillance TADIL-J NPG 8 Mission Management or X.25 NPG 9 Air Control NPG ….

  14. Transition of IP over Link-16 • Plan is for Incorporation of ET in MIDS-JTRS Program • (and other JTRS Clusters) • Enhanced Throughput is a JTRS Requirement • IP Over Link-16 would also be in MIDS-JTRS • As Stand Alone Capability • And Subordinated to Wideband Networking Waveform Layer 3 • WNW IP Layer • Encryption (maybe double encrypt - pending issue on Architecture) • Part of Initial Demonstration Program is to Identify Possible MIDS Backfit if ever Needed.

  15. Possible Approach to Backfit MIDS LVT 1553, X.25 etc MIDS Media Module New IP Ethernet New ET Firmware only Ethernet New ET IP BoD Processor RF Voice-IP SMP DP/Av Mux TP/Gnd Mux Voice VME-16 Bus MIDS Terminal Legend Unchanged Updated
