In the post-pandemic era, ultra-low latency video conmmunications is increasingly popular nowadays. Numerous applications like videoconferencing, cloud gaming, virtual reality, and remote driving are coming or have come to our daily life. However, these interactive video streaming applications require ultra-low and consistent latency to ensure the interactive experience, which challenges how the sender transmits packets and reacts to fluctuations nowadays.

My research rethinks the latency in interactive video streaming in an end-to-end way, and tries to share some preliminary thoughts on what the network and related communities should do to enable the wide deployment of these applications. In this talk, I will present our work on how to achieve a consistent low latency for interactive video streaming. Specifically, I will talk about how we control the tail latency on the transport layer from the perspective of congestion control (Zhuge, SIGCOMM'22) and loss recovery (Hairpin, NSDI'24).
