OPNET simulations were used to evaluate combinations of retransmission mechanisms: TCP, TCP+RLC, and TCP+LLC+RLC. As previous studies, this study indicates that HTTP/FTP goodput is improved with RLC/MAC retransmissions. LLC retransmissions do not improve performance further. The performance may even degrade because of inefficient TCP and LLC interaction.}, url = {papers/pang00_GPRS_retrans.pdf.gz}, bibdate = {Monday, October 15, 2001 at 09:59:33 (CEST)}, submitter = {Annika Wennstr̈{o}m} }
