How to address message to the specific node of the ESB cluster

Question

Hi!
We are running ESB on two node active-active cluster configuration. We use custom adapter to communicate with customer legacy system over Socket connection. The point is, that we need to transfer large amount of data from our database into customer system using one open socket connection. Because of memory limitation we had to split data into multiple messages in ESB. This socket connection can be open from any of the active cluster node, but ones it's open all messages must be send within the node which had open the connection.So, the messages should not arrive into another node. The question: How is it possible to address (route) ESB messages into specific node of the cluster?
Thanks in advance.
Jaro,

Thank you for your reply. It is very useful for me.  But i can't give conditional operator in that operator. It is showing error.
My Test cases
A[0]+A[1]>150
A[31]-50 <100.
If those are your exact statements, then they don't make sense in a formula node.  You have to use them in an if-statement or some other type of control logic.  This mimics text-based programming languages such as C... See here for instructions on formula node syntax: http://zone.ni.com/reference/en-XX/help/371361G-01​/lvhowto/formula_node_syntax/
For instance, you COULD say something like:
**In this example, let A[0] == x, A[1] == y, A[31] == z**
if(x+y>150)
/* do something if this is true */
else if(z-50 < 100)
/* do something else */
EDIT: 
It should also be noted that Variable Names MUST be lowercase!! I just discovered this
EDIT2:
I stand corrected.  After trying to create an example and digging through the LabVIEW Help, I stumbled across this:
Differences between the Parser in the Mathematics VIs and the Formula Node
The parser in the Mathematics VIs supports all elements that Formula Nodes support with the following exceptions:
Variables—Only a, a0, ..., a9, ... z, z0, ..., z9, are valid.
Logical, conditional, inequality, equality—?:,, &&, !=, ==, <, >, <=, and >= are not valid.
Functions—atan2, max, min, mod, pow, rem, and sizeOfDim are not valid. You can use these functions in a Formula Node or use their corresponding LabVIEW functions.
So it DOES NOT seem like Eval Formula Node can do conditionals like you want.  I would just implement them using a LabVIEW based algorithm after all.  Trying to out smart the formula nodes to avoid simple LabVIEW code is just too much of a hassle
