Ratio (session)

Hi Everyone,

 

I am studying for the 201 exam and can't seem to find any information on a particular load balancing technique.

 

The guide states "The ratio-based load balancing methods are: Ratio (node, member and sessions), Dynamic Ratio (node and member), and Ratio Leased Connections (node and member)".

 

The particular part of this I am confused about is "Ratio (sessions)". I have tried this particular technique on my pool and I continually got mapped to the same server over and over. I can't seem to find anything that explains this method in detail.

 

The resource quoted for this topic is

 

https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-concepts-11-4-0/5.htmlconceptid

 

I could not find anything for "Ratio (sessions)" on this page. Can somebody please explain or provide me a resource that explains this method in detail?

 

Thanks in advance.
