Media QoE Enhancement With QUIC -- Infocom 2016 Demo Track

The demonstrated system is an online video streaming service using QUIC protocol as transport. Video buffer status information is gathered at the client side and it is transferred to the video content server via the object priority assignment method of QUIC. Our proposal is to utilize the priority information for congestion control (CC) influence as well. In our realization, the server extracts the priority information and utilizes it to adjust the aggressiveness level of the CC of TCP emulation in QUIC. The measured gain in initial buffering time (IBT) in the demonstrated system is in the range of 6-49% depending on the video properties and network environment.
