ATI's IP Networking Over Satellite course

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.more info View course sampler Instructor: Burt H. Liebowitz is Principal Network Engineer at the MITRE Corporation, McLean, Virginia, specializing in the analysis of wireless services.
