Buffer in IceCast

[Taner Sener]

Hello,

I'm trying to establish a radio station using Icecast but I need a recommendation about a problem. I hope you can give me some tips about the issue.

My case is: my icecast server and ice cast client are in different locations and connection between these two is not so healthy. Sometimes network problems causes client to loose connection with server and this causes server to broadcast silence to the listeners. I want to get rid of this. What I wonder is if IceCast Server buffers some amount of time before broadcasting it to the listeners. I mean the stream data in the buffer can be broadcasted to listeners when connection between server and client is lost. I think if there is such kind of implementation it can help me on solving this issue.

Thanks,

How long are these interrupts caused through network failure?

Does your client (streamer) not reconnect automatically?

It happens sometimes after 3 hours, sometimes after 24 hours and lasts for 15-20 seconds. The problem is caused by my ISP actually and I can not do anything from ISP side.

My client reconnects offcourse but server is playing silence during the failure.

Actually my IP is static,

My ISP is changing the route (my path to IceCast server). It takes more than 10 seconds to recover also I'm loosing the connection.

Ups…

Is it possible to place a second (backup) streamer in another network and you define a fallback mount?

Well I am just a user from a radio station in germany, too. These are just some ideas to maybe help you.

For the buffering thing you asked for you have to wait for the correct answer of the developer.

The only backdating/reserving of stream data is done for the initial
burst. In these cases it's difficult to handle well if you truly lose
the connection, you can of course increase the source timeout and/or
have a huge burst size (eg 1 Meg). These may be all you need but it
really does depend on the circumstances leading up to the source client
disconnection.

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

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.

                      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
