   Workshop:
Improving the Performance of TCP Over Satellite Networks

DC Palter
Vice President, Sales and Marketing
Mentat Inc.

The TCP/IP protocols that are used to transfer data over the Internet and most other computer networks were never designed for satellite link conditions and can suffer severe performance limitations. Fortunately, a variety of solutions are available to overcome these limitations and offer connectivity over satellite comparable in performance to terrestrial options.

The primary focus of this workshop is to provide a foundation for understanding the basic design of TCP/IP, explain the causes of its limitations in the satellite environment and review the different approaches for overcoming these limitations. Topics that will be covered include:

  • Describe the design of TCP/IP and how it works in a satellite environment
  • Explain in detail the causes and limitations of TCP over satellites
  • Describe in detail the design and implementation of protocol gateways and how they overcome the limitations of TCP
  • Discuss the uses and limitations of the following approaches to improving satellite network performance:
  • Enhancements / modifications to TCP/IP
  • Alternative satellite protocols
  • Multicasting
  • Data compression
  • Spoofing
  • Protocol Gateways
  • Caching

   Workshop:
Analyzing the Broadband Satellite Systems and Ventures

Roger Rusch
President
TelAstra, Inc.

Robert Sharples
President
Sharples & Associates

This workshop will provide tools and techniques for evaluating satellite business plans. The session will begin with a brief overview of the types of satellite communications services which are being proposed and developed. Next, there will be a short review of some of the most significant risk issues in satellite communications including the use of non-geostationary satellites, elliptical orbits, time delay (latency), service quality, link margins, rain fading, elevation angles, onboard processing, passive intermodulation problems, and intersatellite links.

This workshop will primarily examine the practical elements of a business case. The sessions provide tools and techniques for testing the validity or credibility of each element of the pro forma. It is designed to examine the defining elements of the program. Examples will be taken from current programs. Among the aspects which will be reviewed are:

Market demand predictions: Why have some estimates been highly inaccurate? What methods provide better estimates? Computation of satellite capacity. How can you determine capacity?

Capital cost estimates for satellites, launch vehicles, and insurance: What tools are available to estimate costs and anticipate overruns?

Program development schedules: How long will it really take to build the system?

Operational cost for satellite systems: What does it cost to operate satellites? How many satellites will need to be replaced due to failures?

Service provider costs: What cost does the service provider have? How much of the retail revenue goes to the service provider and to the satellite operator?

Expenses for equity and debt: What returns do equity partners expect? What interest rates are paid for project debt financing?

Revenue ramp up: How rapidly will customers adopt the service? Earth terminal costs. What factors determine the terminals cost and acceptability?

Regulatory issues: What rules or laws could limit profit potential?
