Get Node URL from LB1

[Gabor Nagy]

Hi,

We have put in place a two instances of flashphoner and configured the LB, I can see in the CLI that both are recognized as active, however what is the URL the client has to hit to get the actual WSS url from the LB (as described per https://docs.flashphoner.com/display/WCS5EN/Balancer+architecture)?

Hello

We didn't test this load balancer in high-load production.
So you may need to consider your own load balancer which points to one of your servers.
It can be nginx or HAProxy balancers which can handle a lot of websocket connections.
In high-load environments we use
1. CDN 2.0 configuration.
https://docs.flashphoner.com/display/WCS5EN/CDN+2.0
2. HA proxy balancers.

I'll keep that in mind, however the idea was to use the LB just to query for the "best" server to start a new stream on, connecting directly to the server instead of going thru a proxy. In that scenario we still need the url

HTTP: http://WCS_HOST:8081/?action=server_list
HTTPS: https://WCS_HOST:8444/?action=server_list

For client to connect to a node returned by load balancer, load balancer URL has to be passed when connection session is created:

Flashphoner.createSession({urlServer:LB_HOST, lbUrl:"http://WCS_HOST:8081/?action=server_list"})

or

Flashphoner.createSession({urlServer:LB_HOST, lbUrl:"https://WCS_HOST:8444/?action=server_list"})

If load balancing is disabled, or no nodes are available or enabled, connection will be established to address in 'urlServer' parameter.
