With HAProxy, you could just define a list of target servers. You'd configure your app to talk to the HA IP, and then each request would go to next available server in the pool you have defined.<br>
<br>
You could also simply do a DNS round robin if you wanted. All depends on what infrastructure/etc. you have available to you and how resilient it needs to be.<br>

Dear Nathan,<br>
<br>
I think I've missed something. I don't understand how HAproxy and Floating IP and KeepAlived will help me? I need to<br>
have all Active FS Servers and some mechanism to send ESL commands to them in round-robin fashion. I've an autodialer<br>
script so that Proxy will help me use many FS Servers at the same time !<br>
<br>
Thanks,<br>

You might look at the keepalived page on wiki, that's what I use to float an IP in the case where only one of the FS<br>
instances should be online.<br>
<br>
You could also use HAProxy to define a group of systems for it to talk to if you want multiple to be online at once,<br>
but rotating between them.<br>

Hi Nathan,<br>
<br>
I can only think of Round Robin with failover. I definitely don't want to parallel fork an ESL command.<br>

Are you saying "round robin" or "mirrored" for the commands?<br>
<br>
i.e. if you send a command over this proxy, would it be duplicated to all of the FS servers, or sent to "first<br>
available"?<br>

Dear Users,<br>
<br>
I have come up with a requirement to have ESL connection made with multiple FS Servers at the same time<br>
and send<br>
them<br>
commands(no event receiving is required for now) The connections to FS should be pooled and monitored<br>
if any FS<br>
goes down.<br>
<br>
Is there any ESLproxy available to be used readily?<br>
<br>
Thanks,<br>
Sammy<br>
