Internet Service via Broadband Satellite Networks

چکیده
The demand for Internet bandwidth has grown rapidly in the past few years A new generation of broadband satellite constellations promise to provide high speed Internet connectivity to areas not served by optical ber cable or other high speed terrestrial connections However using satellite links to supply high bandwidth has been di cult due to problems with ine cient performance of the Internet s TCP IP protocol suite over satellite We describe an architecture for improving the performance of TCP IP protocols over heterogeneous network environments especially networks containing satellite links The end to end connection is split into segments and the protocol on the satellite segment is optimized for the satellite link characteristics TCP congestion control mechanisms are maintained on each segment with some coupling between the segments to produce the e ect of end to end TCP ow control We have implemented this design and present results showing that using such gateways can improve throughput for individual connections by a large factor over paths containing a satellite link

متن کاملAn architecture for Internet service via broadband satellite networks
High bandwidth satellites hold out the promise of a rapidly deployable communications infrastructure with a natural support for mobility. However, the Transmission Control Protocol, widely used in the Internet, performs poorly over satellite links, and this presents an obstacle to the deployment of such systems. We present an architecture that overcomes these problems and provides an approach t...
متن کاملIP routing issues in satellite constellation networks
The growth in use of Internet-based applications in recent years has led to telecommunication networks transporting an increasingly large amount of Internet Protocol (IP)-based traffic. Proposed broadband satellite constellation networks, currently under development, will be required to transport IP traffic. A case can be made for implementing IP routing directly within the constellation networ...
