Abstract :
We provide link layer new data and retransmission buffer size distributions for HTTP and FTP applications in an IS-2000 system. The results are given for different TCP window size, TCP segment size, air link FER and data rates. For HTTP application, the number of parallel TCP connections is limited to either 1 or 4. We found that smaller (larger) new data buffers (retransmission buffers) are required at higher data rates. Moreover, for error free transmission over the air link, a large fraction of data (from TCP window) stays in the new data buffers while for the case of link errors, the retransmission buffer size is also large. The maximum retransmission buffer size is a function of the air link RTT (i.e. number of rounds of RLP NAKs) and is independent of the link error rate
