Differences between public and private peering on IX (traffic exchange point)?

Question

Computer networks

I want to know the differences between public and private peering at a traffic exchange point.
Let's say I have a YouTube site.
If I buy a 10 Gb port in the MSK-IX general peering, will this mean that users who will be connected to the provider participating in the MSK-IX general peering will receive content not via the Internet, but through the general peering?
Or do you need to negotiate with each peering participant?

Answer 1

You will have clean 20Gbit. And you already decide where, what, why. And you will be pulled only in the case of organs and that's it.

Answer 2

Public peering - when you make BGP with route-server MSK IX, private - when directly with operators present on IX. Services like YouTube usually take public, and backbone operators take private.
