N2 - There have been many researches to improve the performance of TCP operating in wireless link. A lot of prior work in this direction, however, has focused on avoiding the case of a TCP sender misinterpreting packet losses in the wireless link as congestion signals. In CDMA2000, however, a reliable RLP ensures that packets are delivered in order and help to recover form packets received in error. In this paper, we have measured the performance of transport layer protocols on a nationally deployed commercial CDMA2000-1x network. We used a cellular phone itself to measure the performance through modifications of Qualcomm TCP/UDP stack. We mainly focus on the large delay variation and excessive queueing in CDMA2000-1x. And it is evitable for traditional TCP to accumulate segment at the buffer of bottleneck link, because TCP's congestion control algorithm would fill the entire router buffer before incurring packet loss. The primary goal of our work is to analyze the exact characteristics of CDMA2000-1x, and maintains the queue length at bottleneck link can be stable without changing the TCP sender.
