Nimbostratusi have a question regarding LTM which is as follows:-
Using Persistence, when an external user from a single host opens two different browsers requesting same resource from the internal server with load balancing set as ROUND ROBIN, how the LTM manages this request and how will be the traffic flow from USER-to-SERVER and vice-versa.
CumulonimbusThis depends on the persistence you have configured for the Virtual Server.
For source address then the persistence is done on the Client IP address, as seen by the F5, so all traffic from the client would be sent to the same pool member regardless of how many browsers they had open.
For any cookie persistence it would be based on the browser, so if a user had two different/independent browsers open each would have it own cookies and so persistence would be per browser.
Think about what did of data the F5 would look at to create/lookup persistence records, e.g. if something is sent by the browser (cookies and headers) then persistence will be per browser.
