Flash Player 10 and Adobe AIR 1.5 introduce a new communications protocol called the Real-Time Media Flow Protocol (RTMFP). The most important features of RTMFP include low latency, end-to-end peering capability, security and scalability. These properties make RTMFP especially well suited for developing real-time collaboration applications by not only providing superior user experience but also reducing cost for operators.
In order to use RTMFP, Flash Player endpoints must connect to an RTMFP-capable server, such as the Adobe Stratus service. Stratus is a Beta hosted rendezvous service that aids establishing communications between Flash Player endpoints. Unlike Flash Media Server, Stratus does not support media relay, shared objects, scripting, etc. So by using Stratus, you can only develop applications where Flash Player endpoints are directly communicating with each other.
How will I make a P2P connection through Flash Player 10 or Adobe AIR 1.5? Connections from a SWF through an RTMFP-capable server will be assigned a temporary unique ID that is infeasible to guess or forge. Other SWFs connected to the same server can subscribe to the streams and events from that ID once the broadcasting SWF agrees to the connection.
Can I get started with RTMFP now? Stratus will allow you to begin developing RTMFP-enabled applications. It will be available on Adobe Labs before the end of the year.
