<div>I am using mod_event_socket in inbound mode to receive events and send actions to FreeSWITCH and mod_xml_curl to return dialplans over HTTP. I have multiple FS servers and multiple servers running my application. Currently I have a 1-to-1 mapping between each FS server and a server hosting my application. I want to remove the 1-to-1 mapping and have my application on one server take over the mod_event_socket connection to FS in another server if the application crashes.</div>
<div><br></div><div>The plan is to have multiple app instances connected to multiple FS instances where every instance of my app would be connected to every FS server in its group. In order to do this, it looks like I would have to use filters to avoid receiving the events for all the channels on all my app instances all the time. So, when starting the mod _event_socket connection I'd have to do something like this on all my app instances:</div>
<div><br></div><div>events plain all</div><div>filter Event-Name CHANNEL_CREATE</div><div><br></div><div>And then when a channel is created and all my app instances receive the CHANNEL_CREATE event, have one of them "win" and assign the channel to it. That instance will then issue the following action over mod_event_socket:</div>
<div><br></div><div>filter Unique-ID <channel_id></div><div><br></div><div>The problem I see with this scheme is that I would probably end up with hundreds of filters per mod_event_socket connection. From what I've seen in the code, the filters are kept as a linked-list. This means that for each event fired, a list of hundreds of elements will have to be evaluated every time, which is obviously undesirable.</div>
<div><br></div><div>Does anybody know of a better way to do this?</div><div><br></div><div>Thanks,</div><div><br></div><div>Juanjo</div>
