"Further Results on UBR+: Effect of Fast Retransmit and Recovery," ATM Forum/96-1761, December 1996

In a previous contribution, we studied the performance of TCP over UBR+. We showed that TCP perfor- mance improves by adding EPD and Fair buffer management techniques over UBR. In this contribution we study the effect of Fast Retransmit and Recovery on these enhancements. In general, Fast Retransmit and Recovery improves the performance of TCP over UBR. However in some cases, the performance is degraded. The incremental gain with Fair Buffer Allocation over simple selective drop using per-VC accounting is small.
