Converge: QoE-driven Multipath Video Conferencing over WebRTC

Cross-layer host-network co-design for QoS in streamed video data networking

“…Coverage [144] presents a multipath video conferencing platform that is compatible with WebRTC. Unlike conventional video streaming applications which manage video data by segments for encoding and decoding, WebRTC processes video data at the granularity of individual frames.…”

“…QUIC [66] is a user-space protocol with multipath implementations, e.g., PQUIC [30] and XLINK [202]. Other application layer multipath so-lutions, e.g., MP-H2 [122], MP-DASH [53] and Converge [144] runs at the application layer using multiple transport layers connections. However, to create multiple paths for a single connection, multiple network interfaces, such as Wi-Fi and 4G, are required.…”

“…Designing a network that offers the ability to handle uncertain latency objectives involves two primary approaches, namely on-host and in-network. On-host solutions focus on packet prioritization on hosts leveraging multipath transport [45,202,144]. A client can leverage multiple network interfaces on the end device to establish a multipath connection to the application server, which mostly includes a fast path and a slow path.…”
