Abstract

Representative embodiments are disclosed of a real-time priority-based communication system and method for communicating media streams made up of multiple media message sub-streams, the communication system comprising a chunk configurator for dividing media message sub-streams into chunks, a state machine configured to translate between information regarding the media message sub-streams and the chunks and state associations to the information, the state associations written into a header for each of the chunks, a queue for holding the chunks waiting to be transmitted, and a processor for executing a scheduling algorithm, wherein the scheduling algorithm determines ones of the chunks in the queue to transmit next.

Claims

1. A method comprising:

establishing a communication session to communicate a media stream, wherein the media stream comprises sub media streams;

associating priority values with the sub media streams;

generating a total priority value based on the priority values;

calculating desired transmission proportions corresponding to the sub media streams based on the priority values and the total priority value;

communicating a set of real-time priority based network communications over the sub media streams;

assessing sub media stream counts corresponding to the sub media streams based on the communicated set;

summing a total count based on the sub media stream counts;

determining actual transmission proportions corresponding to the sub media streams based on the sub media stream counts and the total count;

figuring ratios corresponding to the sub media streams based on the desired transmission proportions and the actual transmission proportions; and

storing the figured ratios.

2. The method of claim 1, further comprising:

selecting a low-ratio sub media stream corresponding to a lowest of the stored ratios;

queuing a set of real-time priority based network communications to be communicated over the sub media streams;

picking a low-ratio sub media stream network communication, associated with the low-ratio sub media stream, from the queued set; and

communicating the low-ratio sub media stream network communication over the low-ratio sub media stream.
