Requirements for Real-time Transport Services

As part of our work on TCP Hollywood, we've sketched out requirements for the transport services and APIs needed by real-time applications, such as telephony, video conferencing, and video streaming. Stephen McQuistin presented these at the ACM, IRTF, and ISOC Applied Networking Research Workshop in Berlin, on 16 July 2016 (slides), and in the IETF Transport Services working group later that week.

The talk gives an overview of the limitations of existing transport protocols when applied to multimedia transport, and the problems of ossification in the network. It discusses the features that we would want from an ideal multimedia transport protocol, and an appropriate API, and outlines how TCP Hollywood can address many of these needs.
