CONGESTION CONTROL BITRATE ALGORITHM
First Claim
1. A method comprising, with a sender computing system:
- sending, via an unreliable protocol, a stream of data packets to at least one recipient device over a network, the stream of data packets including source packets and forward error correction (FEC) packets;
during said sending, receiving one or more feedback reports from the at least one recipient device, each said periodic feedback report characterizing packet loss during a respective period of time; and
during said sending, adjusting a rate at which said data packets are sent in the stream in response to at least one of said feedback reports,wherein said adjusting the rate comprises increasing a FEC rate at which the FEC packets are sent while maintaining a source rate at which the source packets are sent in response to a particular one of the feedback reports which characterizes the packet loss as within an acceptable level.

Abstract
The method may include sending, via an unreliable protocol, a stream of data packets to at least one recipient device over a network. The stream of data packets may include source packets and forward error correction (FEC) packets. The method may include, during said sending, receiving one or more feedback reports from the at least one recipient device, each said periodic feedback report characterizing packet loss during a corresponding period of time. The method may also include, during said sending, adjusting a rate at which said data packets are sent in the stream in response to at least one of said feedback reports. Adjusting the rate may include increasing a FEC rate at which the FEC packets are sent while maintaining a source rate at which the source packets are sent in response to a one of the feedback reports which characterizes the packet loss as within an acceptable level.

15. A sender computing system comprising:
-
at least one processor unit; at least one memory unit coupled to the at least one processor unit; wherein the at least one processor unit and the at least one memory unit are configured to perform a method, the method comprising; sending, via an unreliable protocol, a stream of data packets to at least one recipient device over a network, the stream of data packets including source packets and forward error correction (FEC) packets; during said sending, receiving one or more feedback reports from the at least one recipient device, each said periodic feedback report characterizing packet loss during a respective period of time; and during said sending, adjusting a rate at which said data packets are sent in the stream in response to at least one of said feedback reports, wherein said adjusting the rate comprises increasing a FEC rate at which the FEC packets are sent while maintaining a source rate at which the source packets are sent in response to a particular one of the feedback reports which characterizes the packet loss as within an acceptable level. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A non-transitory computer readable medium having computer readable instructions embodied therein, the computer readable instructions being configured to implement a method when executed, the method comprising:
-
sending, via an unreliable protocol, a stream of data packets to at least one recipient device over a network, the stream of data packets including source packets and forward error correction (FEC) packets; during said sending, receiving one or more feedback reports from the at least one recipient device, each said periodic feedback report characterizing packet loss during a respective period of time; and during said sending, adjusting a rate at which said data packets are sent in the stream in response to at least one of said feedback reports, wherein said adjusting the rate comprises increasing a FEC rate at which the FEC packets are sent while maintaining a source rate at which the source packets are sent in response to a particular one of the feedback reports which characterizes the packet loss as within an acceptable level.
