System and method for dynamic rate adaptation based on real-time call quality metrics

A computing device, comprising:

• one or more processors;
• and
• a memory having instructions stored thereon, which when executed by the one or more processors, cause the computing device to perform operations including:
• transmitting, by a network device, a sampling packet for an upstream traffic and a downstream traffic including a transmit timestamp at an interval, wherein the interval is adjusted based on one or more of a per packet basis and a per client basis;
• receiving an acknowledgement packet comprising a receipt timestamp;
• determining a call quality of service, by the network device, for the upstream traffic and the downstream traffic based on a comparison of the transmit timestamp and the receipt timestamp for each of the upstream traffic and the downstream traffic, wherein the call quality of service is associated with a real-time streaming packet received at an upstream traffic transmission rate and a downstream traffic transmission rate;
• and
• adjusting the upstream traffic transmission rate and the downstream traffic transmission rate to a second upstream traffic transmission rate and a second downstream traffic transmission rate, respectively, based on the call quality of service for each of the upstream traffic and the downstream traffic, and based on call quality metrics including a reliability of a transmission of the real-time streaming packet and a transmission delay.

A computer-program product tangibly embodied in a non-transitory machine-readable storage medium, including instructions configured to cause a data processing apparatus to:

• transmit, by a network device, a sampling packet for an upstream traffic and a downstream traffic including a transmit timestamp at an interval, wherein the interval is adjusted based on one or more of a per packet basis and a per client basis;
• receive an acknowledgement packet comprising a receipt timestamp;
• determine a call quality of service, by the network device, for the upstream traffic and the downstream traffic based on a comparison of the transmit timestamp and the receipt timestamp for each of the upstream traffic and the downstream traffic, wherein the call quality of service is associated with a real-time streaming packet received at an upstream traffic transmission rate and a downstream traffic transmission rate;
• and
• adjust the upstream traffic transmission rate and the downstream traffic transmission rate to a second upstream traffic transmission rate and a second downstream traffic transmission rate, respectively, based on the call quality of service for each of the upstream traffic and the downstream traffic, and based on call quality metrics including a reliability of a transmission of the real-time streaming packet and a transmission delay.
