@bmork I wonder whether you can offer any insight into 4G/5G in respect of how download and/or upload saturation is expected to affect one way delays (measurable using ICMP type 13 or irtt) in both the download and upload directions?
On my connection I am seeing a noticeable increase in upload one way delay on saturating download, whereas on saturating upload there is not a similar increase in download one way delay.
Does this make sense to you?
This seems odd because ordinarily download saturation results in primarily only an increase in download OWD and upload saturation results in primarily only an increase in upload OWD. Or at least that was my understanding up until now. @tievolu is that what you see on your connection?
Here is download followed by upload:
