Abstract
A method for determining quality of an audio and video stream includes: obtaining a key indicator for a target audio and video stream, the key indicator including at least one of the following indicators within a reference time period: a maximum quantity of continuously lost packets, an average packet receiving time interval, an average packet receiving time interval variance, or a quantity of stream interruptions; and determining a QoE of the target audio and video stream based on the key indicator.
Claims19
A method for determining quality of an audio and video stream, the method comprising:
- obtaining a key indicator within a reference time period for a target audio and video stream, the key indicator comprising a maximum quantity of continuously lost packets, the obtaining the key indicator comprising:
- obtaining a maximum quantity of continuously lost packets value for each sub-time period of a plurality of sub-time periods in the reference time period;
- and
- selecting a largest maximum quantity of continuously lost packets value as the maximum quantity of continuously lost packets;
- and
- determining a quality of experience (QoE) of the target audio and video stream based on the key indicator.
A network device, the network device comprising:
- a memory storing instructions;
- and
- a processor coupled to the memory, the processor is configured to execute the instructions to implement:
- obtaining a key indicator within a reference time period for a target audio and video stream, the key indicator comprising a maximum quantity of continuously lost packets, the obtaining the key indicator comprising:
- obtaining a maximum quantity of continuously lost packets value for each sub-time period of a plurality of sub-time periods in the reference time period;
- and
- selecting a largest maximum quantity of continuously lost packets value as the maximum quantity of continuously lost packets;
- and
- determining a quality of experience (QoE) of the target audio and video stream based on the key indicator.
A non-transitory computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out the following steps:
- obtaining a key indicator within a reference time period for a target audio and video stream, the key indicator comprising a maximum quantity of continuously lost packets, the obtaining the key indicator comprising:
- obtaining a maximum quantity of continuously lost packets value for each sub-time period of a plurality of sub-time periods in the reference time period;
- and
- selecting a largest maximum quantity of continuously lost packets value as the maximum quantity of continuously lost packets;
- and
- determining a quality of experience (QoE) of the target audio and video stream based on the key indicator.
