Extended (packet level) stats

Postby DonMcL » 24 Apr 2017 22:49

Background:

We are looking at demoing the potential use of LTE at 28 GHz. Those who must be obeyed want to use a video app as test traffic. (We're expecting vlc).
We can get physical level stats like receive level/SNR etc from the radios.
We can get video layer stats from vlc (bytes read, frames displayed, frames lost).
We would like to add something in the middle like packet level stats such as min/avg/max end-to-end latency (delays in packet delivery/reception) and packet loss and/or reordering stats.


Questions:

If hosts are synchronised (e.g. via NTP) are any of the SCR PCR PTS DTS usable to calculate and monitor min/avg/max end-to-end latency?
Are there any sequence numbers (onger than the 4-bit continuity counters?) that could be used to calculate and monitor packet level loss and/or out of sequence arrival stats?

Are such stats possible to obtain?

If so, any guidance on where/how to start would be helpful.


Offer:

If these are possible, and are within my capability, I'd be willing to feed back anything usable I produce.

Thanks,
Don
