Abstract

We address the interaction between TCP and RLC (Ra dio Link Control), the link layer retransmission protocol in W-CDMA, a 3rd generation cellular wireless network tech nology, in evaluating TCP performance in following points; 1)Suppress delay-jitter in link layer to avoid excess retrans missions. 2)Clarify the trade-off between jitter-suppression and link utilization to improve TCP throughput. 3)Optimize the link layer and TCP parameters. We show how to find the TCP and link ARQ parameters that yield optimum over-all performance; simulations and emulation confirm their effectiveness. The coexistence of ARQ and TCP can lead to inefficient interaction; the delay-jitter on the link layer may trigger spurious TCP retransmission. The solution is to suppress jitter on the link layer. To manage the trade-off between this suppression and link utilization, we optimized with link parameter.
