Congestion Control for Interactive Media: Control Loops and APIs

Varun Singh, Jörg Ott and Colin Perkins

Internet Architecture Board (IAB)/Internet Research Task Force (IRTF) Workshop on Congestion Control for Interactive Real-Time Communication, Vancouver, Canada, July 2012.

Standardisation of Web Real-Time Communications (WebRTC) and Telepresence will likely lead to greatly increased deployment of interactive multimedia applications on the Internet. The resulting high-rate multimedia traffic may cause congestion, but few congestion control solutions have been proposed. We suggest that the congestion control, codec, and application be coupled and engage in a dialogue on the correct response to congestion; and that congestion control consider semantic feedback, not just transport-layer metrics.
