BurstRTC: Harnessing Variable Bit-Rate of RTC through Frame-Bursting Congestion Control
Zhidong Jia, Zhang Yihang, Qingyang Li, Xinggong Zhang · 2024
The rapid growth of online interactive video applications reflects the increasing popularity of real-time communication (RTC). Despite advancements in network and video technologies, the worse quality of experience (QoE) such as large delay, rebuffering and low image quality, etc. remains to be complained generally. We argue that this is mainly due to the legacy network-oriented congestion control (CC), which assumes continuous stream of packets are sent. But it is not satisfied for RTC since bit-rate variation is inherent to RTC’s video encoder.
