FStream: Flexible Stream Scheduling and Prioritizing in MultipathQUIC While the web keeps evolving, web latency remains a major obstacle to improving user experience. In the past, many efforts have been made in this course. SPDY achieves reduced latency through multiplexing and prioritization by manipulating HTTP. Quick UDP Internet Connection (QUIC) generalizes the idea and embeds multiplexing in the transport layer by introducing applicationoriented streams. MultipathQUIC brings further improvements by utilizing multiple paths as is done in MultiPath TCP (MPTCP). However, failing to account for stream priorities in the transport layer can result in suboptimal performance for timecritical streams. We fill this gap and propose FStream xe2x80x93 a flexible stream scheduling mechanism for MultipathQUIC, which provides stream prioritization down to the transport layer. We implement FStream in MultipathQUIC and demonstrate its effectiveness in reducing the completion time of timecritical streams (xcbx9c3x) through extensive experiments under different path dissimilarity conditions.

Path Switching Schedulers for MPTCP Streaming Video Recent developments on multipath transport protocols have allowed video streaming transmissions over multiple interfaces, improving session reliability as well as bandwidth performance. One important aspect of multipath transport is the selection of paths on a packet by packet basis. In particular, path switching may cause head of line blocking effects that may impact video rendering. In this work, we analyze the impact of path switching on multipath video streaming, and propose new path schedulers aimed at reducing path switching. We utilize network performance measures, as well as video quality metrics, to characterize new schedulersu0027 performance improvements and interactions between network and application layers of video streams for various network scenarios.
