I am looking for advice on technique or products that can solve the
following challenge ...
Two private line T1's between A and B - one terrestial T1 with >200 ms RTT,
the other T1 is over satellite with ~500 ms RTT. The circuits are being used
for mixed VoIP (70%) and data (30%) applications. To achieve optimal voice
quality, we want to route all VoIP calls over the terrestial T1 until it is
"full", then divert all subsequent VoIP calls over the satellite T1 (**
while existing VoIP calls continue to be routed over the terrestial T1).
So it looks like I need per-flow (based on protocol, src IP, dst IP, src
port, dst port) routing. It looks like MPLS Traffic Engineering can do the
job. Is there anything else that can it with less complexity?
Ideas or recommendations?
Regards,
Joe
