The problem is with the destination not receiving acknowledgments of TCP packets within a minimum time which causes the packets to be resent under the assumption that they never arrived. This is seen as congestion between the satellite and its base station and causes the sliding window to shrink and thus reducing throughput. This can be mitigated through some clever routing where a ground based host acts as a proxy to the satellite, immediately acknowledging the packets then forwarding them on to the satellite. </ins></div></td></tr> <tr><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"></td><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"></td></tr> <tr><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"><div>==VSAT==</div></td><td class='diff-marker'> </td><td style="background: #eee; color:black; font-size: smaller;"><div>==VSAT==</div></td></tr>  </table>
