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)

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

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

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.
