How permanent is the ShoutCast yp link?

[someToast]

I'd like to take advantage of the load balancing of ShoutCast's yellow pages station link by posting that link on my station's web page.

http://www.shoutcast.com/.../shoutcast-playlist.pls?rn=6892&file=filename.pls

Just how permanent is that "6892" identifier? Is it maintained as long as my server is available? Will it be reassigned during those times when my server gets no response from the yp? What if my server's name string changes?

Once your server disconnects and then reconnects, it changes.

Just use your IP as your station link, no biggy. Or get a No-IP link from http://www.no-ip.com.

But my understanding is, that if I point to the IP of my primary server, once that is full people will be blocked, even though the relay still has a number of slots open.

Or am I misinterpreting this? (Please tell me that I'm misinterpreting this.)

Of course my cable would have to go out right now for the first time in months.

Just set your primary server to allow 1 listener, and to allow only relay connections. Then allow your relay to connect to the SC Primary server on your connection. That is what I best recomend

[JoeDeeJay]

Ok im pretty embarassed but what is www.no-ip.com and what can i get from it or what does it do?

[DJHotIce]

No-IP.com is a leading dynamic DNS service provider. We offer a wide range of services pertaining to your internet presence, from that pesky dynamic IP problem to getting around ISPs who block port 25. All of our services take advantage of our global network of redundant DNS and mail servers peered with tier-1 data centers.

But that sounds like offloading all traffic to the relay. I want both the primary server and the relay to share the listener load.

Ok then. when they click the SC link it will attempt to ballance the weight

Check out the results from a SHOUTcast forum search on 'load balancing'.

Look for a post by danielsan titled:
equal serverload without a cluster?

Note: Other search criteria may yield more results.

Alternativeley, check out Radio Toolbox.

I'm seeing many of the same pages for a "load balancing" search as I did this morning for "relay".

I probably shouldn't have said "share the load." I'm fine with the primary server having 5 listeners and the relay having one. My concern is people being needlessly locked out of one or the other.

In my limited tests, it appears that even with both server addresses in the .pls file, the audio client only retains the IP address it connected to at the time. What happens if ten people try to connect with the relay address (which they happened to be shunted to on their previous visits). Does the relay know enough to send them back to the primary server's open slots? Can it be told to?

[FesterHead]

If the main DNAS is full, listeners get directed to a relay.

If the relay(s) is(are) full, listeners get directed to the main DNAS.

If they're all full, the listener gets bounced.

Excellent. This is exactly what I was looking for. Thanks!

Excellent. This is exactly what I was looking for. Thanks!

Now I just have to edit the web page so it culls listener stats from both servers.

Just an FYI Radio toolbox provides dynamic load balancing for your listeners as of the latest version, just go to the web admin panel and click listen with all your servers listed, it uses percentage rather then listener count to determine the best servers to send people to.

Alright, I found a script on this site somewhere, which i modified for my own site, so im going to post my modification here, You might see this script somewhere (thanks to whoever posted it - forgot who)

But anyways, it didnt have listener count on it, like the shoutcast.com cluster link did, so i pretty much made it identical to the cluster link, here it is

code:


<? 

##Settings## 



//Define all servers here (add more if needed) 

$server_address[0]='65.75.186.30'; 

$server_port[0]=8400;

$server_address[1]='67.19.102.78'; 

$server_port[1]=8010; 

$server_title[1]='fuseRADIO 24/7 Mix'; 



$server_address[2]='67.19.102.78'; 

$server_port[2]=8012; 

$server_title[2]='fuseRADIO 24/7 Mix';

} 

} 

} 



} 

elseif($mode=='load_balancing'){ 

//This is really not a good way to do this since each request will 

//query all the servers. It would be better to have a cache that is updated

//server. 

for($i=0; $i<count($server_address); $i++){

//be faster since in the other random there are only as many random numbers as servers

//of getting repeats is much less meaning less time in the for loop that makes sure the 

//random numbers are unique. 

mt_srand((double) microtime() * 1000000);

This is the script i use,
theres 2 copies of it of you guys wanna test it out, links should be in my sig, else here they are again :P

Have fun.

theravenz, stop digging up old threads trying to show off the script.

I don't see anything funny about this, and please read the rules which you agreed to about signature size, yours is way over the line.
