Is it possible that BIG-IP loadbalances TCP Packets indivisually ?

Well, you could certainly inspect each piece of data sent across from the client.

 

 

To do this you'd have to set the connection to a collect state (TCP::collect), load balance appropriately, and then release the connection (TCP::release) each time data was passed through.

 

 

This should be taken care of by the default load balancing mechanism you're using for your VIP, though. I would imagine you would be better off just configuring your VIP to load balance every new post to a different server, rather than trying to analyze things on a per packet basis and load balance appropriately.

If you want to just arbitrarily load-balance each TCP packet individually, you could try this rule:

when CLIENT_ACCEPTED {
   TCP::collect
}
when CLIENT_DATA {
   LB::detach
   TCP::release
   TCP::collect
}

This will cause the back-end server to be detached on each packet then then the load-balancing engine would re-load balance and re-attach to the new server.

If you have some sort of transactional boundary that you want to load-balance, then you would need to add logic to search for that boundary and do the detach & release logic much more carefully. There are some examples of this on codeshare under transactional load-balancing.

Oh, forgot to mention that you would probably want OneConnect otherwise the back-side servers will incur the 3WHS for each packet.
