Abstract:

In the post-pandemic era, interactive video streaming applications like
videoconferencing, cloud gaming, and virtual reality are coming or have
come into our daily life. However, the Internet is not ready for those
applications so far. The main reason is that those applications have
stringent requirements on not only the latency but also the latency
variation -- even 01% of video frames stall will degrade the users'
experiences a lot. Unfortunately, although network researchers have
optimized the latency for decades from different aspects, few of them are
towards the latency variation

We investigate the latency variation in interactive video streaming and
try to identify and control the latency variations to enable the
deployment of these applications. In this talk, I will present our work on
how to control the latency variation across the network stack.
Specifically, I will talk about how we control the latency variations
caused by the fluctuations in the application layer, and by the congestion
feedback from the network to end hosts.
