This contribution presents the simulation results on the performance of TCP enhancements over ATM-UBR+ for satellite latencies with limited switch buffers for WWW traffic. We analyze the impact of Fast Retransmit and Recovery (FRR or Reno), New Reno, Selective Acknowledgement (SACK), Early packet drop (EPD), and Selective Drop on LEO, MEO, and GEO satellite configurations for several buffer sizes.
