IP Convergence:
The Future of Satellite Communications
Simon Stewart
Satellite Gateway Technician
What is IP Convergence?
• The transmission of different types of
traffic over a single “converged” network
– Voice
– Video
– Data
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)
• 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
• 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
