Abstract-- In this paper, a new optimal policy is introduced
to determine and adapt the Generalized MultiProtocol Label
Switching (GMPLS) network topology based on the current traf-
fic load. The Integrated Traffic Engineering paradigm provides
mechanisms for dynamic addition of physical capacity to optical
networks. In the absence of such mechanisms, the rejection of
incoming requests will be higher. The objective of the proposed
policy is to minimize the costs involving bandwidth, switching
and signaling. The policy is derived by utilizing the Markov
Decision Process theory. The new policy is split into two levels:
the MPLS network level and the optical network level. In addition
to the optimal policy, a sub-optimal policy and a threshold-
based policy are also proposed which are less computationally
intensive but have comparable performance to the optimal policy.
