Abstract

Systems, methods, and non-transitory computer-readable storage media for implementing real-time transport control protocol (RTCP) to obtain end-to-end session information. The system receives an RTCP extension that is associated with an RTCP packet in a communication session. The RTCP extension may include an instruction for transmitting RTCP data based on a triggering event. The RTCP extension can be configured to propagate along the communication session. Next, in response to the triggering event, the system can transmit the RTCP data to an address defined by the instruction as a destination address for receiving information associated with the triggering event.

First claim

We claim:

1 . A method comprising:
receiving, by a first endpoint participating in a communication session conducted over an outward media path from the first endpoint to a second endpoint through a conferencing server, one or more real-time transport control protocol messages, the outward media path comprising a first media leg and a second media leg; based on the one or more real-time transport control protocol messages, determining, by the first endpoint, a first quality score for the first media leg and a second quality score for the second media leg; and generating an outward communication quality report based on the first quality score and the second quality score.

2 . The method of claim 1 , wherein the communication session is further conducted over an inward path from the second endpoint to the first endpoint through the conferencing server, the inward media path comprising a third media leg and a fourth media leg.

3 . The method of claim 2 , further comprising:
based on the one or more real-time transport control protocol messages, determining, by the first endpoint, a third quality score for the third media leg and a fourth quality score for the fourth media leg; and generating an inward communication quality report based on the third quality score and the fourth quality score.

4 . The method of claim 1 , further comprising:
generating an overall communication quality report based on the outward communication quality report and the inward communication quality report.

5 . The method of claim 1 , further comprising:
determining, based on the outward communication quality report, how well a first participant associated with the first endpoint can be heard by a second participant associated with the second endpoint.

6 . The method of claim 1 , wherein the one or more real-time transport control protocol messages are received from nodes along the outward media path.

7 . The method of claim 1 , further comprising:
receiving, by the first endpoint, additional real-time transport control protocol messages related to a third endpoint participating in the communication session, wherein the communication session is conducted further over a second outward media path from the first endpoint to the third endpoint through the conferencing server, the second outward media path comprising a third media leg and a fourth media leg; based on the additional real-time transport control protocol messages, determining, by the first endpoint, a third quality score for the third media leg and a fourth quality score for the fourth media leg; and generating a second outward communication quality report related to the first endpoint and the third endpoint based on the third quality score and the fourth quality score.

8 . A system comprising:
a processor; and a computer-readable storage medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
receiving, by a first endpoint participating in a communication session conducted over an outward media path from the first endpoint to a second endpoint through a conferencing server, one or more real-time transport control protocol messages, the outward media path comprising a first media leg and a second media leg;
based on the one or more real-time transport control protocol messages, determining, by the first endpoint, a first quality score for the first media leg and a second quality score for the second media leg; and
generating an outward communication quality report based on the first quality score and the second quality score.

9 . The system of claim 8 , wherein the communication session is further conducted over an inward path from the second endpoint to the first endpoint through the conferencing server, the inward media path comprising a third media leg and a fourth media leg.

10 . The system of claim 9 , the computer-readable medium storing additional instructions which, when executed by the processor, cause the processor to perform further operations comprising:
based on the one or more real-time transport control protocol messages, determining, by the first endpoint, a third quality score for the third media leg and a fourth quality score for the fourth media leg; and generating an inward communication quality report based on the third quality score and the fourth quality score.

11 . The system of claim 8 , the computer-readable medium storing additional instructions which, when executed by the processor, cause the processor to perform further operations comprising:
generating an overall communication quality report based on the outward communication quality report and the inward communication quality report.

12 . The system of claim 8 , the computer-readable medium storing additional instructions which, when executed by the processor, cause the processor to perform further operations comprising:
determining, based on the outward communication quality report, how well a first participant associated with the first endpoint can be heard by a second participant associated with the second endpoint.

13 . The system of claim 8 , wherein the one or more real-time transport control protocol messages are received from nodes along the outward media path.

14 . The system of claim 8 , the computer-readable medium storing additional instructions which, when executed by the processor, cause the processor to perform further operations comprising:
receiving, by the first endpoint, additional real-time transport control protocol messages related to a third endpoint participating in the communication session, wherein the communication session is conducted further over a second outward media path from the first endpoint to the third endpoint through the conferencing server, the second outward media path comprising a third media leg and a fourth media leg; based on the additional real-time transport control protocol messages, determining, by the first endpoint, a third quality score for the third media leg and a fourth quality score for the fourth media leg; and generating a second outward communication quality report related to the first endpoint and the third endpoint based on the third quality score and the fourth quality score.

15 . A computer-readable storage device storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
receiving, by a first endpoint participating in a communication session conducted over an outward media path from the first endpoint to a second endpoint through a conferencing server, one or more real-time transport control protocol messages, the outward media path comprising a first media leg and a second media leg; based on the one or more real-time transport control protocol messages, determining, by the first endpoint, a first quality score for the first media leg and a second quality score for the second media leg; and generating an outward communication quality report based on the first quality score and the second quality score.

16 . The computer-readable storage device of claim 15 , wherein the communication session is further conducted over an inward path from the second endpoint to the first endpoint through the conferencing server, the inward media path comprising a third media leg and a fourth media leg.

17 . The computer-readable storage device of claim 16 , storing additional instructions which, when executed by the processor, cause the processor to perform further operations comprising:
based on the one or more real-time transport control
