On Performance Modeling of TCP New-Reno
Kaiyu Zhou, Kwan Lawrence Yeung, Victor O. K. Li · 2007
In this paper, we evaluate the performance of New- reno analytically by explicitly modeling its slow-start, congestion avoidance, fast retransmit, fast recovery and retransmission timeout mechanisms. Two packet loss models, bursty and independent, are adopted in our study. The accuracy of our proposed New-reno model is verified by simulations. The performance of New-reno is then compared with Sack using the derived analytical models. We show that New-reno outperforms Sack when the round trip time is short and the bursty loss event probability is low.
