Question

Live stream to multiple FMS servers behind load balancer

Hi,
I have a setup where I have 2 FMS 3.0 servers behind a load balancer. This works fine for VOD files but when I started testing a live stream, it intermittently hangs and no video shows up about 50% of the time. I'm assuming this is because only one of the servers is actually getting the live stream from Flash Media Live Encoder (I have the RTMP string set to flv.domain.com which is load balanced between the two servers).

How do I keep the two servers in sync for live streaming? Do I need to setup an edge/origin configuration? Since I didn't change any of the defaults when installing the software, I would assume that both are running as origin servers. Is there a config I need to change?

Any help would be appreciated.

    You might want to try out Multipoint publish feature of FMS. Using this, server-side app on one FMS can publish a stream to another FMS. If properly managed it might help to ensure that all streams are available at every FMS behind your load balancer.

    edge-origin is also beneficial. It depends on the scale & type of your app go for a mix of edge origin/mutipoint publish.
    Personally, I think that multipoint publish alone should suffice for smaller cluster.
