IP Networking Over Satellite Performance and Efficiency
This two-day course is designed for satellite engineers and managers in military, government and industry who need to increase their understanding of how to reduce satellite networking costs in mission critical applications. IP has become the worldwide standard for converged data, video, voice communications in military and commercial applications. Satellites extend the reach of the Internet and mission-critical Intranets. Satellites deliver multicast content anywhere in the world. New generation, high throughput satellites (HTS) provide lower cost transport for IP. With these benefits come challenges. Satellite delay and bit errors can impact performance. Satellite links must be integrated with terrestrial networks. IP protocols create overheads. Encryption creates overheads. Space segment has been expensive (but HTS provides the potential for significant cost reduction). There are routing and security issues. This course explains techniques that can mitigate these challenges, including traffic engineering, quality of service, WAN optimization devices, TDMA DAMA to capture statistical multiplexing gains, improved satellite modulation and coding, what applications are most amenable to support from HTS. Quantitative techniques for understanding throughput and response time are presented. System diagrams describe the satellite/terrestrial interface. Case histories illustrate methods for optimizing the design of converged real-world networks to produce responsive networks while minimizing the use and cost of satellite resources. The course notes provide an up-to-date reference. An extensive bibliography is supplied.
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 Internet-over-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.
