IP Convergence:

The Future of Satellite Communications

Simon Stewart

Satellite Gateway Technician

what is ip convergence
What is IP Convergence?
  • The transmission of different types of traffic over a single “converged” network
    • Voice
    • Video
    • Data
the benefits of ip convergence
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 development transformational communications architecture tca
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
phase one limited ip system overview
Phase One: Limited IP System Overview
  • Net-centric Router
  • Voice Gateways
  • HAIPE
  • Intrusion detection devices
  • The Performance Enhancing Proxy

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
