• Virtual Private Network (VPN)

13
Content Distribution

• Delivery
• Internet Protocol
• Multicast File Transfer Protocol
• MPEG2/DVB Standard

14
Proving the Concept

• Reliable multicast works over satellite
• testing with Starburst Software
• We are doing it today, even as we speak...

VELOCITY

• MPEG-2/DVB
• Point to Multi-point
• One-way broadcast
• data
• video
• audio

17
ChannelCasting
ChannelCasting permits users to transmit their
own content to their own audience on their own
schedule - all via satellite.
18
ChannelCasting

• Digital broadcasting of content
• Broadcasts a single stream of digital material to
  multiple locations at high speeds.
• True push technology, requiring no intervention
  by the destination point.

19
Receive Sites

• Antenna
• .9M in most locations
• Receiver
• can be box or card
• 400-700 range
• Complete package for less than 1k per site

20
Objectives

• Seamless integration of satellite and terrestrial
  networks
• Building an IP Multicasting network (Private or
  Public)
• Network abstraction, not knowing where your
  bandwidth is coming from

21
Thinking Outside the Box

• Working with terrestrial
• supplementing satellite with terrestrial or vice
  versa
• satellite as a backup or disaster recovery
• using the strength of both technologies

22
What to Look Out For...

• Compatibility with existing network standards
• Open architecture
• Careful vendor selection
• Contingency planning
• Advancing technology to reduce terrestrial
  dependence
