Transcription de la présentation

  1. IP Convergence: The Future of Satellite Communications Simon Stewart Satellite Gateway Technician

  2. What is IP Convergence? • The transmission of different types of traffic over a single “converged” network • Voice • Video • Data

  3. The Benefits of IP Convergence • A converged IP network • IP is an open standard • Easily scalable • Capable of CoS and QoS-based routing • Fewer components in the network • Elimination of multiple networks operating in parallel.

  4. IP Modem Architecture IP Modems Provide Efficient Bandwidth Utilization • Differs From Basic Satellite Modems in Their Ability to Efficiently Transport IP Data Over the Satellite Link • Uses Time Division Multiple Access (TDMA) Framing Structure Bandwidth on a Single Carrier

  5. Timeline for Development:Transformational Communications Architecture (TCA) • Legacy Design – 2004 - 2005 • Phase One Limited IP – 2006 • Phase Two Expanded IP – 2007 - 2008 • Phase Three Full IP – 2008 - 2012

  6. Phase One: Limited IP System Overview • Net-centric Router • Voice Gateways • HAIPE • Intrusion detection devices • The Performance Enhancing Proxy

  7. Phase Two: Expanded IP System Overview • IP Modems are installed (iDirect, Linkway) • Support 4 Wideband RF Interfaces • Support Hub/spoke and Mesh Topology • Utilize Dynamic Bandwidth Resource Allocation • Upgraded Converged IP Suites • Ensure Compatibility With various terminals • Enhances Bandwidth availability

  8. Expanded IP Architecture

  9. Ku-band (Eutelsat EB4) Phase Two Linkway Equipment Shelter Terminal 6 Modem: Linkway Services: Voice, Video, Data 2.25 MSPS x 4 Pre-Positioned Services 2.25 MSPS Terminal 7 Modem: Linkway Services: Voice, Video, Data 2.25 MSPS Central Network 2.25 MSPS 2.25 MSPS Linkway Terminal 8 Modem: Linkway IP Services: Voice, Video, Data Terminal 9 Modem: Linkway IP Services: Voice, Video, Data Network Manager Network Controller

  10. Ku-band (Intelsat IS-903) Phase Two iDirect Equipment Shelter Terminal 1 Modem: iDirect 7350 Services: Voice, Video, Data 512 Kbps Pre-Positioned Services Central Network Terminal 2 Modem: iDirect 7350 Services: Voice, Video, Data 2048 Kbps iDirect 512 Kbps Terminal 3 Modem: iDirect 7350 Services: Voice, Video, Data Network Manager Network Controller

  11. Net-Centric Enterprise Service integrated • Future IP modem with Embedded TRANSEC • Enhances bandwidth capability further • Other future requirements yet to be determined Phase Three: Full IP Implementation

  12. Summary • Taking Steps Toward Realizing the Transformational Communications Architecture (TCA) • IP Transition Will be Incremental • Benefits of IP Convergence • Limited IP • Expanded IP • Fully Implemented IP • Keys to Success: Requirement Solidification, Program Synchronization, and Funding
