Load balancer for several edge servers

[gs4l]

Hello,
I am using origin-edge clustering and webRTC streaming deployed in kubernetes cluster.

The load balancer sends the webRTC signalling request to one of the edge server and when the same client tries to establish webRTC connection, the load balancer sends the request to different server and the connection cannot be established.

Anyone faced a similar scenario like this? How to resolve it?

I think you need to use a sticky (session-based) load balancer. HAProxy can do this. What are you using now?

Hi

I am using traefik as load balancer. I will need to implement sticky session on TCP level but it it not possible in traefik as far as I know. Traefik only supports cookie based sticky sessions

[bchah]

Correct, Traefik does sticky sessions for HTTP routes only. You could try placing an HAProxy instance in front of it to handle the TCP load balancing...

I always use DNS RR method because when you have too many viewers, your Load Balancer might not be able to handle it.

Configure each OME server to have a different port for TURN server and a separate Ingress for each port on TCP level, routing traffic to the correct server.
