Ratio (Session) and Least Sessions

Thanks everyone for the reponses

I do understand how the ratio should function generally, but the key point I still didn't fully grasp is the context of a session in the Ratio(Session) option,

As far as I know, TCP connections don't hold any session information, every connection is separate, for example HTTP works on TCP, it's a stateless protocol, so the session for the client is stored in a cookie header that is presented by the server and saved on the client, this way we understand how the load-balancer will understand what a session means (the cookie value presented in the persistence table is what determines which TCP connections belongs to which client session).

But the question in the Ratio(session) option what counts as a session for multiple TCP connections, in the docs it's mentioned that Ration(session) requires L7 profile, but how would the F5 know how to differentiate which TCP connection belongs to which session. unless it's in a persistence table or additional properties in that L7 profile, I don't see another way to differentiate between sessions.

For the Least Sessions it's clear on the docs that it depends on persistence table, but for Ratio(session) this is not mentioned.

I hope I made my self clear.

Thanks
