Hi,

I did send a mail to atlas@ripe.nl. I never received an answer although it's 19 days ago. Not sure if staff is reading here, but let's see.

This graph shows pings to a mobile device. A device connected to a mobile network. As mobile networks need to do paging and need some time to re-establish the radio connection, more time is needed for the packets in the first 2 or 3 seconds to get through.

My request is to consider making a configurable timeout value for pings? For mobile networks a typical RTT for a first packet would be some 3 seconds. There are however buffers in a typical mobile network which store packets up to 30 seconds in case multiple pagings would fail. I really would like to be able to have a timeout maximum of just over 30 seconds but I could understand if you would limit on 5 seconds.

Below, I kept a continuous ping open parallel to the Atlas tests in the marked timeframe. Therefore no paging was needed as the radio channel was kept open all the time. It seems the current timeout is 2 or 3 seconds.

Regards,

Dave Boonstra.
