A method of real-time, dynamic allocation of multimedia streams enables large-scale, server-routed real-time conference (multipoint and interactive broadcast) sessions within advancing communication technologies such as open-standard WebRTC (Web Real-Time Communications) A Synchronization Source (SSRC) mapping concept/technique is used to efficiently manage required real-time renegotiation of media flow correlations (MFC) between session participants in a server-routed conference through the Real-time Transport Protocol (RTP) processor (Engine), collectively RTP Engine. The RTP Engine is a logic processing element that inputs RTP media packets, manipulates the information within the RTP packets, and outputs the modified RTP packets. The SSRC Mapping through the RTP Engine enables the conference server router to isolate the renegotiation to a single offer/answer exchange between a participant changing a media flow correlation and the conference server router. The result is significant real-time interactive performance, efficiency, and capability benefits to server-routed multipoint/broadcast conferences designed for global-scale applications.

Synchronization source (SSRC) mapping for real-time interactive multipoint server-routed conferencing with dynamic renegotiation of multimedia-sending participants

The RTP Media Conference Server Routing Engine ('MCSRE') integrates into a standards based RTP Media Server to improve server data throughput of RTP conference routing by factors of tens to hundreds while simultaneously decreasing real-time media delivery delays and significantly decreasing server resource requirements. The RTP MCSRE maintains a conference routing database used to manage a large number of conferences with a list of associated RTP sessions and conference participants. The routing engine also includes a Conference Session Routing Filter ('CSRF') and a Routing Logic Processor (&#x201c;RLP&#x201d;) that selectively route received media streams to each participant in a given RTP conference. The behavior of both the CSRF and the RLP can be modified by executable scripts. The RTP MCSRE imposes floor control rules and packet filtering with regard to both network bandwidth and hardware resources specific to conference participant endpoint devices.
