Abstract

A computer has a processor and a memory connected to the processor. The memory stores instructions executed by the processor to receive a real time communication request from a client device and perform an evaluation of the number of client devices associated with the real time communication request. The evaluation results in the coordination of peer-to-peer communications in the event of two client devices and an attempt to host a real time communication session using a first protocol in the event of three or more client devices. A second protocol for the real time communication session is invoked in the event that the attempt to host the real time communication session using the first protocol is unsuccessful.

Claims

1. A computer, comprising:

a processor; and

a memory connected to the processor, the memory storing instructions executed by the processor to;

receive a real time communication request from a client device,

perform an evaluation of the number of client devices associated with the real time communication request, wherein the evaluation results in the coordination of peer-to-peer communications in the event of two client devices and an attempt to host a real time communication session using a first protocol in the event of three or more client devices,

invoke a second protocol for the real time communication session in the event that the attempt to host the real time communication session using the first protocol is unsuccessful, and

designate client device feed qualities by modulating at least one of target bitrate, size of video feed and number of frames per second, based upon an evaluation of at least one of real time transport control protocol receiver report messages from the client devices, uplink adaptation monitoring to detect packet queuing delay, packet loss and jitter, and downlink adaptation monitoring of a high quality video feed and a low quality video feed.

2. The computer of claim 1 wherein the memory stores instructions executed by the processor to attempt to transition the real time communication session from the second protocol to the first protocol in response to first protocol connectivity success.

3. The computer of claim 1 wherein the real time communication session supports audio and video on a single communication channel.

4. The computer of claim 1 wherein coordination of peer-to-peer communications includes coordination of User Datagram Protocol peer-to-peer communications.

5. The computer of claim 1 wherein the first protocol is the User Datagram Protocol.

6. The computer of claim 1 wherein the second protocol is the Transmission Control Protocol.

7. The computer of claim 1 wherein the memory stores instructions executed by the processor to coordinate the peer-to-peer communications after confirming that the first protocol communication is operative for the two client devices.

8. The computer of claim 1 wherein the memory stores instructions executed by the processor to collect network stream quality measurements from client devices.

9. The computer of claim 8 wherein the network stream quality measurements include loss packet measurements and one-way packet queuing delay measurements.

10. The computer of claim 1 wherein the memory stores instructions executed by the processor to send real time transport control protocol receiver report messages to the client devices.

11. The computer of claim 1 wherein the memory stores instructions executed by the processor to designate client device feed qualities based upon peer-to-peer adaptation monitoring of a single communication session between the two client devices.

12. The computer of claim 1 wherein the memory stores instructions executed by the processor to host a plurality of real time communication sessions.

13. The computer of claim 12 wherein the memory stores instructions executed by the processor to dynamically distribute load across the plurality of real time communication sessions.

14. The computer of claim 1 wherein the memory stores instructions executed by the processor to host an application program interface operative to supply analytics on real time communication sessions.

15. The computer of claim 1 wherein the memory stores instructions executed by the processor to supply to a client device a prompt regarding charges associated with a real time communication session.

16. The computer of claim 15 wherein the memory stores instructions executed by the processor to supply a client device with prompts for choosing a payment method for the charges.
