One or more computing devices, systems, and/or methods for delivering video streams are provided. In an example, a first video stream chunk of a video stream is received. The first video stream chunk is transmitted to a first client device in response to a determination that the first video stream chunk is not associated with a quality issue. A second video stream chunk of the video stream is received. The second video stream chunk is analyzed to determine whether the second video stream chunk is associated with one or more quality issues. A first quality issue associated with the second video stream chunk is detected. A request for a corrective video stream chunk is transmitted to a cache node based upon the first quality issue. The corrective video stream chunk is received from the cache node. The corrective video stream chunk is transmitted to the first client device.

Detecting a quality issue associated with a video stream delivery

A system receives a data unit from a sending node and identifies if the data unit indicates that it is a test data unit. The system determines a delta time that includes a difference between a time at which a response data unit is going to be sent to the sending node and a time at which the data unit was received. The system inserts the delta time, if the identification indicates that the data unit is a test data unit, in the response data unit and sends the response data unit to the sending node.
