  1. “Approaches to Interoperability Standardization”by Timothy Schoechle, PhDCyberLYNX Technology CorporationBoulder, Colorado, USAfor National Conference on Emergency Communications SystemsWashington DCDecember 12-13, 2005hosted byGeorge Washington University

  2. Situation • Technological advances in wireless networking • Many new technologies and standards • Targeted to specific applications and services • Not interoperable

  3. Some examples • Local area networks • Bluetooth • Zigbee (IEEE 802.15.4) • WiFi (IEEE 802.11) • UWB • Wide area networks • WiMAX (IEEE 802.16) • LMDS, MMDS • GSM/GPRS • CDMA • 3G • CDMA 2000 • WCDMS • TS-SCDMA

  4. Some examples • Satellite services • SDR (Software Defined Radio) • JTSR (Joint Tactical Radio System) • US military system • Specialized fixed and mobile services • NGN (Next Generation Networks) • ITU-T SG 13—NGN • ITU-T SG 16—Multimedia Trmls, Sys. & Apps • Focus on ”ubiquitous applications” • e-everything (e.g., e-health, e-business, etc.)

  5. The problem • Compatibility • Not interfering with each other • Connectivity • Talking to each other • Interoperability • Understanding each other • “Interworking”

  6. The problem • Interoperability • Between wired and wireless networks • Between new and legacy networks

  7. Issues and problems • The “stovepipe” problem • New systems need “legacy bridge” • Future-proofing • “technology insertion”—Avoid re-engineering • “sustainability” • Compatibility with civil & national systems

  8. OSI 7-layer model(open system interconnect) USER USER “Gateway” Application Layer 7 Application Presentation Layer 6 Presentation Session Layer 5 Session Transport Layer 4 Transport “Router” Network Layer 3 Network Data Link Layer 2 Data Link “Bridge” Physical Layer 1 Physical Network 2 Network 1

  9. Internet • A “network of networks” • At the network layer (OSI layer 3) • Layer 3 interconnection • Connectivity vs. interoperability • Connectivity: message packet exchange • Interoperability: application language translation • Syntax • Lexicon • Semantics • Now: take the Internet logic to the next stage • Gateway: application layer (OSI layer 7)

  10. Solution • ISO/IEC 15045 Gateway • Defines generalized gateway architecture • Modular and distributed structure • Integrates with voice, video, and data services • ISO/IEC 18012 Guidelines for Interoperability • Translates between dissimilar networks • At the OSI Application layer (layer 7) • All protocols and languages accommodated

  11. Gateways! Public Safety Network (FM, P25,SDR) Gateway Gateway JTRS Military Network (over 30 air interfaces) Gateway Federal Gateway Tribal State Allies Local Same MILDEP Different MILDEP Gateway Gateway Commercial Wireless Networks (2G, 3G, SDR) U.S. Rest of World

  12. Abstract Intermediate Language (AIL) GIWF #1 #1 <> AIL GIWF #2 #1 <> AIL GIWF #3 #1 <> AIL GIWF #4 #1 <> AIL System #1 System #2 System #3 System #4 Common Interoperability Framework(ISO/IEC 18012) GIWF = Generic Interworking Function

  13. Gateway Architecture(generalized) Wide Area Networks Local Area Networks LAN 1 Interface WAN 1 WAN 1 Interface LAN 1 WAN 2 LAN 2 WAN 2 Interface LAN 2 Interface WAN 3 LAN 3 WAN 3 Interface LAN 3 Interface Domain ofGateway Standard Gateway Intermediate Bus and Protocol Minimal Network Services Encryption Services Authentication Services Enhanced Network Services Other Services Other Security Services Core Framework

  14. Gateway Architecture(Home Networking Example) Wide Area Access Networks Local Area Networks MPEG-Video Cable TV DOCSIS Interface IEEE 1394 Telephone WiFi DSL Interface VoIP Interface WiMAX Ethernet Receive Interface Data Router Domain ofGateway Standard Gateway Intermediate Bus and Protocol Health/Medical Monitoring Automatic Meter Reading Personal Vidoe Recorder Energy Management Network Management Security/Firewall Services Core Framework

  15. The JTSR example • Sound architectural concept • SCA—Software Communications Architecture • Software-based—re-usable hardware • Modular “waveforms” for expandability • But… • Radio only • Few waveforms—need to add new technology faster • No connection to other new & legacy networks • Need WNW—Wideband Network Waveform • Costs out of control • Delays in implementation

  16. JTRS Set Architecture(Software Radio Networking Example) Waveforms WNW Minimal Network Services Core Framework Programmable Radio Hardware

  17. JTRS Gateway Architecture(Software Radio Networking Example) Radio Set Waveforms WNW Waveforms WNW Interface 1 SINCGARS Waveform 1 GIG EPLRS Internet Waveform 2 WNW Interface 2 HAVEQUICK C2 Waveform 3 WNW Interface 3 Domain ofGateway Standard Gateway Intermediate Bus and Protocol Minimal Network Services Encryption Services Authentication Services Enhanced Network Services Other Services Other Security Services Core Framework
