I`m glad to inform you that at September 2012 we will present highly important release of Flashphoner product. That release will contains RTMFP protocol support
RTMFP protocol based on UDP and much better suited for voice and video calls, against to RTMP that based on TCP.
“The principle difference is how the protocols communicate over the network. RTMFP is based on User Datagram Protocol (UDP), whereas RTMP is based on Transmission Control Protocol (TCP). UDP‐based protocols have some specific advantages over TCP‐based protocols when delivering live streaming media, such as decreased latency and overhead, and greater tolerance for dropped/missing packets, at the cost of decreased reliability.”
Based on our tests, RTMFP will reduce latency twice in average and up to ten times in bad networks.
