Techniques to avoid useless packet transmission in multimedia over best-effort networks
Jizhong Jim Wu · 2022
In this thesis, we investigate Useless Packet Transmission (UPT) problem in best-effort netwoks supporting multimedia, and propose an algorithm called Useless Packet Transmission Avoidance (UPTA) to address the UPT problem. UPTA can effectively eliminate transmission of useless multimedia packets, and allocate the recovered bandwidth to competing TCP flows. As a result, UPTA improves TCP throughput and reduces file download time with no significant impact on overall intelligibility of multimedia applications. UPT is
