“…WebRTC flows are highly affected by connection latency, which should be kept as low as possible to guarantee QoE. Thus, congestion control is of paramount importance and new algorithms are being developed, such as Network Assisted Dynamic Adaptation (NADA) [66], developed by Cisco, or Self-Clocked Rate Adaptation for Multimedia (SCReAM) [40], developed by Ericsson. Both algorithms are currently being standardized in the IETF Media Congestion Avoidance Techniques (RMCAT) working group.…”

“…These solutions yield good performance under the specific network conditions, but can not improve the performance of video streaming transmission. The algorithms specially designed for real-time video transmission mainly include [15,21,41]. They use packet loss and delay as congestion metrics, and empirically set some fixed thresholds.…”

“…We contribute to a better understanding of coupled congestion control by covering a wide range of congestion control mechanisms used for real-time media, background-transfer, and web-like traffic. An extensive experimentation of the proposed solution has been done, using the six congestion control mechanisms: 1) Rate Adaptation Protocol (RAP) [18], a simple rate based AIMD protocol; 2) TCP Friendly Rate Control (TFRC) [19], because it updates the rates based on an equation, and is currently the only standardized congestion control mechanism aimed at supporting media flows; 3) Network Assisted Dynamic Adaptation (NADA) [20], a work-in-progress congestion control algorithm for webRTC; 4) Google Congestion Control (GCC) [13], another workin-progess congestion control mechanism for webRTC, and is currently deployed in web browsers (Chrome, Firefox); 5) Low Extra Delay Background Transport (LEDBAT) [21] because it is a delay-based mechanism, and very well known as a less-than-best-effort transport protocol for services such as operating system updates; and 6) Transmission Control Protocol (TCP), because it is the most widely used transport protocol for web-like traffic as well as bulk transfers.…”
