ospf bandwith

Hi! I have a large network that was working in a large bridge.
i have changed all the routers to a routed scenario and implemented ofpf.

Everything is working fine but id like to know how i change traffic routes if link bandwith is in high levels.

I have made some searchs and i have found that ospf + mpls + te is the solution. Am i in the correct aproach?

Thanks in advance.
