How satellite service providers integrate their systems with the customer's
computer network can make the service a success or failure. If done correctly, integration
software can increase the "quality of service" or realized throughput of the
data delivery service. Good software can also protect the service provider from customers
overusing or hogging the bandwidth. Issues to be discussed include:
- Advanced Packet Filtering
- Dynamic Service Multiplexer technology

Synopsis:
The TCP/IP protocols used to transfer data over the
Internet were never designed for conditions typical of satellite communications. The poor
performance of the TCP protocol under the long latency, high bit error rates, and
asymmetric bandwidth associated with satellite networks is one of the primary limitations
to efficient, high speed Internet access using satellites.
To overcome these limitations, a variety of
solutions have been proposed, including modifications to the TCP protocol, data caching,
spoofing, and the use of alternative protocols. This presentation will explain how TCP
reacts to satellite conditions and review a survey of proposed solutions. Finally, the
presentation will focus on protocol gateways as the best solution for offering high
performance Internet access via satellite.
