DMOC Mission Statement

• DMOC serves as Aerospace Command and
  Control's tactical-level synthetic battlespace
  hub by integrating and scheduling resources, by
  developing scenarios, by providing virtual
  adversary support, by linking to operational and
  strategic-level simulations, and by performing
  lead agent responsibilities for Aerospace Command
  and Control Synthetic Battlespace inter-team
  training events

Virtual Flag Network Description

• DMOC Network
• Air LAN
• Ground LAN
• Many other smaller LANs
• External Data Links
• T-1 1.5 Mbits/sec bandwidth
• Guardnet, 750 Kbits/sec
• DREN ATM Cloud
• JDEP
• DMON
• Virtual Flag Scenarios
• About 400 600 Air Entities
• About 4,000 9,000 Ground Entities
• Data Protocols
• DIS, HLA, NATO EX, Link-16, TIBS , SAR/NATO-EX
• The Need for Bandwidth Reduction due to various
  connection availability
• Dont want to be limited to the weakest link

8
Bandwidth Reduction Techniques

• Simple Bandwidth Rules
• DIS Filter Analyzer (DFA)
• DMOC Software Router (DSR)

9
Bandwidth Rules

• Only exercise data (DIS/NATO-EX/etc.) during the
  exercise
• No File Transfers during exercise
• Minimize bandwidth use by adjusting DIS Protocol
  Data Unit (PDU) heartbeat rates
• No remote terminal activity on the exercise
  networks
• TIBS/TRAP tactical data transmission on STU IIIs

10
DIS Filter Analyzer (DFA)

• Linux platform
• User configurable gateway (LAN not HLA gateway)
• Multiple NICs
• Filter criteria are applied to PDUs as they are
  read (minimal latency)

11
DFA Capabilities

• Filtering Capabilities
• Exercise Identification (ID)
• PDU Type enabled filter (Entity State Fire
  Detonation Signal Start/Stop etc.)
• Allow/Deny by Site/App/Entity
• Allow/Deny by DIS Enumeration
• Interactions (Fire/Detonation/etc. PDU) from
  denied enumeration are also denied

DFA Capabilities (Cont)

• Range filter
• Spherical range filters
• Allow Entity State PDUs within a range of a
  selected Site/App/Entity ID, or a specific
  latitude/longitude/altitude location
• Control amount of high fidelity data allowed onto
  a LAN

Software Router Overview

• DMOC Software Router (DSR) is a transport utility
  (not related to OSI)
• Minimal impact on existing sites and systems
• Fixed bandwidth, but non-uniform bandwidth load
• Support for all UDP-based broadcast data
• DIS
• NATO-EX
• SAR images
• Free text messages
• Voice over IP

18
Software Router Overview
19
Software Router

• GNU/Linux platform
• Deployability
• Remote operation
• Low cost
• Data metering and buffering
• Maximum packets per second
• Maximum bytes per second
• Packet priority
• Multicast ensures a single copy of data on a
  network

Conclusions

• DIS Filter LAN GATEWAY

• Filtering on the transmitter side (vs. receiver)

• Data-content filtering

• DSR TRANSPORT UTILITY

• Provides data flow metering and priority scheme

• Uses multicast protocol (ATM/network friendly)
