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

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 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 IP Modem Architecture

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. 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 Phase Two: Expanded IP System Overview

8. Expanded IP Architecture

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

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

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

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
