The use case is this. We have an open-source library for a multi-agent system that supports several protocols of the application layer of the OSI model. On the moment HTTP, XMPP, and ZeroMQ are supported for example. We would like to add high-bandwidth real-time streaming possibilities. It is logical to use RTP for that.
So, to recapitulate, we already have a connection to the other party that we can use for signalling. We want to negotiate only a new channel for data communication.
However, regarding the current standards, with respect to signaling all of them seem to be tied to their application. These current "standards" seem to be SIP, RTSP, and Jingle. They all seem to use RTP or SRTP on the application layer, and UDP on the transport layer. See e.g.
The only thing we want to negotiate is another connection to that party that can be used for data transmission. In the
Session Description Protocol
all kind of stuff about media shows up, optional phone numbers, etc. If someone can point at a signaling protocol that is meant to be application-agnostic, that would be great!
