RE: Selecting an ethernet line

["Andy Nolen-Parkhouse" <aparkhouse@xxxxxxxxx>]

Albert,

Below is my understanding.

On the ADDTCPRTE (Add TCP Route) command you have a parameter called
DUPRTEPTY (Duplicate Route Priority).  Valid values are between 1 and 10,
the default is 5.

What you want to do is called outbound load balancing.  If you leave the
DUPRTEPTY at its default value, nothing will happen and the system will
not attempt to manage your outbound traffic.  If you change the values to
equal values other than 5 for both routes, the system will attempt to
balance the number of connections (not actual load) between the two
routes.  If the values are different, the higher number will be the
preferred route.

I realize that you asked about selecting a specific Ethernet line when
opening a socket.  I don't know how to do that, (or if it can be done),
but you might find that the above tip might meet your needs.  The system
will be working with the number of connections, as opposed to throughput,
but if your connections average out, it may suffice.  Set both interfaces
to a value of 6 and see if things are better.  It will do no harm.
