[lymkyuman]

Our customer using this ISP.

There are many times in midnight disconnect issue. the customer tried contact Movistar for check the issue. Moviestar answered it's not our problem.

So I checked MTR log from our service area to user side. there is packetloss in Moviestar side. can you check it please?

Hi @lymkyuman

MTR don't measure in general any real packet lost. MTR use tracert/ping to check latency and other stuff. Any packet lost in MTR is, almost always, only IGMP traffic prioritization/discrimination, so don't have any effect in real traffic.

Anyway, your capture can not be seen yet, I suggest you put it in an external service and put here your link, or copy/paste MTR output.

Hi @lymkyuman

Your destination, 88.18.201.46 is a intermediate node anyway.

Hop nº 10 give you about 5% loss, but if you look at hop 12, you have only a 1%. Real Packet lost, like latency, is accumulative. So if nº 10 have a real 5% loss, them,  in next hops you should have at least a 5% of packet loss. Its pretty normal for intermediate nodes to prioritize IGMP traffic. Sometimes you can see even a 100% "packet lost" in some nodes, but in general, is not truth.
