IP Networking Over Satellite
For Government, Military & Commercial Enterprises
Summary
This three-day course is designed for satellite
engineers and managers in government and industry who
need to increase their understanding of the Internet and
how Internet Protocols (IP) can be used to transmit data
and voice over satellites. IP has become the worldwide
standard for data communications. Satellites extend the
reach of the Internet and Intranets. Satellites deliver
multicast content efficiently anywhere in the world. With
these benefits come challenges. Satellite delay and bit
errors can impact performance. Satellite links must be
integrated with terrestrial networks. Space segment is
expensive; there are routing and security issues. This
course explains the techniques and architectures used to
mitigate these challenges. Quantitative techniques for
understanding throughput and response time are
presented. System diagrams describe the
satellite/terrestrial interface. The course notes provide an
up-to-date reference. An extensive bibliography is
supplied.
Instructor
Burt H. Liebowitz is Principal Network Engineer at the
MITRE Corporation, McLean, Virginia, specializing in the
analysis of wireless services. He has more
than 30 years experience in computer
networking, the last six of which have
focused on Internet-over-satellite services.
He was President of NetSat Express Inc.,
a leading provider of such services. Before
that he was Chief Technical Officer for
Loral Orion (now Cyberstar), responsible for Internet-oversatellite
access products. Mr. Liebowitz has authored two
books on distributed processing and numerous articles on
computing and communications systems. He has lectured
extensively on computer networking. He holds three
patents for a satellite-based data networking system. Mr.
Liebowitz has B.E.E. and M.S. in Mathematics degrees
from Rensselaer Polytechnic Institute, and an M.S.E.E.
from Polytechnic Institute of Brooklyn.
After taking this course you will understand how the
Internet works and how to implement satellite-based
networks that provide Internet access, multicast
content delivery services, and mission-critical
Intranet services to users around the world.
What You Will Learn
• How packet switching works and how it enables voice and
data networking.
• The rules and protocols for packet switching in the Internet.
• How to use satellites as essential elements in mission
critical data networks.
• How to understand and overcome the impact of
propagation delay and bit errors on throughput and
response time in satellite-based IP networks.
• How to link satellite and terrestrial circuits to create hybrid
IP networks.
• How to select the appropriate system architectures for
Internet access, enterprise and content delivery networks.
• How to design satellite-based networks to meet user
throughput and response time requirements.
• The impact on cost and performance of new technology,
such as LEOs, Ka band, on-board processing, intersatellite
links.
