This research includes an amendment to a TCP-Peach+ protocol to improve the performance of the TCP over satellite links, Where the protocol has been proposed based on splitting the connecting path between the source and target, in order to obtain a
n adjusted protocol of the kind of Satellite transport protocol (STP) specialized in the space segment only, and that by proposing a new algorithm for this protocol which is located under the satellite transport layer (STL). We have focused in our research on a comparison between the proposed protocol and TCP-Peach+ protocol.
This research contains an analysis of performance of multiple
access protocols when using for satellite channel to connect between
earth station(HUB) and VSAT through satellite .The performance
of those protocols has been compared through the foll
owing points:
1)the transmission power which is required by the earth station.
2) the transmission power which is required by the satellite's
transponder .
3)the require frequency bandwidth.
4)the maximum number of the earth stations in the network.
5)the delay which is caused by using those protocols.
This study has introduced head lines to choose the proper multiple
access protocol for the required service from the satellite channel
preserving the lowest cost to have the ideal performance for satellite
channel.
