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.

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

Timeline for DevelopmentTransformational
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
