Reiner Ludwig, Keith Sklower, The Eifel Retransmission Timer , CCR, July 2000. This paper proposes a new TCP retransmission timer mechanism, the Eifel retransmission timer. One goal is to prevent the unnecessary retransmissions that can result from a spurious retransmit timeout. This requires using either timestamps or new flags in the TCP header to distinguish between original and retransmitted data packets. A. Aggarwal, S. Savage, and T.

Pacing offers better fairness, throughput, and lower drop rates in some situations.
