ups

delete the word NOT in the first sentence 

I doubt that the change of routes does "not" affect

                      Hi Taner

I doubt that the change of routes does not affect your connection, because
this is normal practise with carriers (BGP or least cost routing) and
usually it has no impact on the enduser, as it happens in milliseconds.
My personal thinking is, that your ADSL Provider disconnects you once or
twice a day to unload the DSLAM port and sometimes, if you do not have a
fixed IP address, you even get a new IP address.
This disconnect takes a bit long to synchronize in your case.
Have you checked that? Look into the logfile of your modem/router.

If so, then force your modem or router to do this disconnect at a fixed time
in the middle of the night.
Which equipment are you using?

Tom

Hi Maarten,

Yes, I'm behind ADSL with PPPoE but I don't think it is related with my
case. When my client disconnects from IceCast server for 15-20 seconds, my
active downloads are not interrupted. It currently  effects only the route
to my IceCast server, other routes looks uneffected. I'm pinging IceCast
server continuously and checking trace route periodically. It is comething
like: my IceCast server is 6 hops far from me and when my connection
goes-gomes it becomes 8 hops far from me. Also some addresses on trace route
are not the same. This is why I see this situation as a route change.

Regards,

Hi,

Are you running behind an ADSL line? If so, what type of ADSL connection
(PPPoA, RFC1483 bridged), what type of router, etc.
Also the line quality (noise margin, line speed, rx/tx attenuation) may be
an important issue. If the line is indeed gone for 15-20 seconds, this
indicates a retrain/relogin of your connection. Maybe the logs from your
modem can tell you more about these outages.

I doubt it is the ISP just changing routes, since the last mile to you is
always using the same route, and re-routing anything beyond that point
will have impact on large numbers of customers. Besides, those wouldn't
take 15-20 seconds.

So, good luck with your new homework ;-)

Regards,
 Maarten
