M3UA Loadsharing over 2 multi-homed links to 2 SG

Hi,


I am using:
     - 1 ASP: SMSC.
     - 1 ASP: MSC.
     - 2 SGP: STP.


In the following schema:

          ASP1
          /    \
         /      \
        /        \
 SGP1       SGP2
        \        /
         \      /
          \    /
          ASP2

My ASP, ASP1, is connected to SGP1 by 4 IP @ and to SGP2 by 4 IP @. ASP1 has
2 associations with each SGP (multi-homed with 2 IP @).


I am going to setup loadsharing of traffic between ASP1 and ASP2 over the
SGP: SGP1 and SGP2 by:

      - Load-share the whole M3UA traffic between SGP1 and SGP2: this is the
first level of load-sharing.

      - Load-share traffic to SGP1 between the 2 associations between ASP1
and SGP1: this is the seconf level of load-sharing.

      - Load-share traffic to SGP2 between the 2 associations between ASP1
and SGP2: this is the third level of load-sharing.


Is that scenario possible with the actual M3UA specification? If not, please
provide an alternative? Any other suggestion? Is that carrier grade
configuration? What about HA: what to do to support that feature in M3UA?


Please help.


Thanking you in advance.
