How can I link some mediasoup servers together?

mediasoup libraries
1

I have some servers that work separately and they’re working great.
I’m using a datacenter that can give me maximum 6 CPUs per server. I need more than this for create large group of consumers. How can I link some mediasoup servers together? Or any other solutions?

Thank you.
Could you please show me where it is or what you call it?

When I have two separate server how can I fill route option of router.pipeToRouter function?
My two router are not located in the same host.
Look at router.pipeToRouter function’s inputs:
pipeToRouter

router.pipeToRouter({ producerId, dataProducerId, router, listenIp });

How can I fill router option of router1 in the server1 with router2 of the other server2.
Thank you.

No, you obviously cannot do that.

This is just a special case when both are on the same machine. If they are not on the same machine you need to connect them manually and explicitly, documentation and tests will help you to achieve that.

In our tests 2 or 3 CPUs with 3 Ghz is enough to saturate a gbit/link with about 1.600 streams with mediasoup. Don’t know why you think you need more CPUs?

Scaling ist more a thing about cascading, we already now have a soultion for this; our project is https://gomeo.io/

Maybe we can help.

Thank you.
I’ve tested mediasoup-demo with this CPU’s detail that can just handle about 50 streams per CPU.
With 4 CPUs I can handle about 200 streams in total.
I have no idea where I was wrong. Maybe my server’s CPU is not good enough?
This is my CPU’s detail:

vendor_id : GenuineIntel
cpu family : 6

We use in production per server, virtualized with XEN, 1.200 streams per 4 core system. The limit is the bandwith of ~100 MB/sek not the CPU. We have high resolutions for the webcams by default.

How do you determine that your CPU is a bottleneck?

I use top command in ubuntu and see every 4 CPUs have about 80-90% usage.
I think you’re CPU is better than mine, isn’t it?
By the way, I’m going to compare your CPU with mine.
Could you help me to find out what’s going on?

We use in production per server

What does it mean? I didn’t get that?

Thank you.

You have much more earlyier all CPUs on 100% than getting performance problems. Tests in my mind/statemens means problems in reality for clients, not just a CPU of 100%.

What exactly is unclear? That we are in production?

Assume that I download the mediasoup-demo and run it with pm2. Am I in production mode now?
You think I was wrong somewhere?
I’m quite sure my CPUs aren’t better than yours, but they’re not that bad and shouldn’t be so far from your result.
I don’t know where I am wrong.
