Retrieving Download Time from the available data set

[Nancy Jia]

Hi,

I am planning to use this data set for a class project to train a PAC model. One of the needed inputs of our training is the download time of the video chunk. 

Because there seems to be no direct data displaying this information, we are thinking that maybe we can retrieve the download time by finding the difference between the time stamps for when the video is sent and when the video is received and subtracting the time it takes for the ack to be sent from the client to the server. 

We wonder if you can provide some insight to this, or if there is a suggested way to find out the download time in anyother way. Thanks!

Hi Nancy,

Thanks for reaching out.

That's exactly how you can compute the "download time" -- search for "matching" in the Data Description page.

Best,

Francis

I read your email more carefully: By matching video_sent and video_acked, you will be able to compute the "round-trip time" of a video chunk. There's no reliable way to accurately compute the "one-way delay" of a video chunk from our data.

Best,

Francis
