Hi
i would suggest u to go with QOS i.e., CBWFQ which is most widely deployed and working fine in most of the production network (which i have seen).
just create different policies based on ur applications or requirements between ur locations.
give more priority or allocate enough B/W under the particular class so that ur mainline application dont get affected.
After cofigurin the classes do create policy maps and bind them under the T-1 interface..
if u still require any info do revert ..
