IP Networking Over Satellite
For Government, Military & Commercial Enterprises
Summary
This three-day course is designed for satellite
engineers and managers in military, 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 in military
and commercial applications. Satellites extend the reach
of the Internet and mission critical 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 ten of which have focused on Internetover-satellite
services in demanding
military and commercial applications. He
was President of NetSat Express Inc., a
leading provider of such services. Before that he was
Chief Technical Officer for Loral Orion, responsible for
Internet-over-satellite 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.
