I'm not sure if I understand your question.  Are you asking what happens
if the traffic running over a RSVP-TE LSP, that was created with a bandwidth
requirement, exceeds that bandwidth requirement?

If so, the short answer is nothing.  The long answer is that it depends
on the implementation, but most (if not all) implementation do not enforce
the RSVP-TE bandwidth requirement, they just used it to help 'fit' LSP during
setup and failure cases.
