Measuring data packet delay in an end-to-end communication path

A method performed by one or more processors of a first computing device, comprising:

• transmitting, to a second computing device, first delay measurement information in a first packet with a header portion configured to indicate that the first packet is a data packet, wherein the first packet includes a first header extension that includes an indication of a first transmit time of the first packet, and the first delay measurement information includes the indication of the first transmit time of the first packet;
• receiving, from the second computing device, second delay measurement information in a second header extension of a second packet with a header portion configured to indicate that the second packet is a data packet, wherein the second delay measurement information includes an indication of a plurality of timestamps, wherein the plurality of timestamps includes the first transmit time of the first packet, a first receive time of the first packet, and a second transmit time of the second packet;
• and
• determining one or more data packet delays, in association with a quality of service for a communication path between the first computing device and the second computing device, based at least in part on one or more of the first delay measurement information or the second delay measurement information.

A computing device, comprising:

• means for transmitting, to another computing device, first delay measurement information in a first packet with a header portion configured to indicate that the first packet is a data packet, wherein the first packet includes a first header extension that includes an indication of a first transmit time of the first packet, and the first delay measurement information includes the indication of the first transmit time of the first packet;
• means for receiving, from the other computing device, second delay measurement information in a second header extension of a second packet with a header portion configured to indicate that the second packet is a data packet, wherein the second delay measurement information includes an indication of a plurality of timestamps, wherein the plurality of timestamps includes the first transmit time of the first packet, a first receive time of the first packet, and a second transmit time of the second packet;
• and
• means for determining one or more data packet delays, in association with a quality of service for a communication path between the computing device and the other computing device, based at least in part on one or more of the first delay measurement information or the second delay measurement information.

A non-transitory processor-readable medium having stored thereon processor-executable instructions configured to cause a processing device in a computing device to perform operations comprising:

• transmitting, to another computing device, first delay measurement information in a first packet with a header portion configured to indicate that the first packet is a data packet, wherein the first packet includes a first header extension that includes an indication of a first transmit time of the first packet, and the first delay measurement information includes the indication of the first transmit time of the first packet;
• receiving, from the other computing device, second delay measurement information in a second header extension of a second packet with a header portion configured to indicate that the second packet is a data packet, wherein the second delay measurement information includes an indication of a plurality of timestamps, wherein the plurality of timestamps includes the first transmit time of the first packet, a first receive time of the first packet, and a second transmit time of the second packet;
• and
• determining one or more data packet delays, in association with a quality of service for a communication path between the computing device and the other computing device, based at least in part on one or more of the first delay measurement information or the second delay measurement information.
