Abstract: An integrated IP over Optical Network controlled by the Generalized Multi-Protocol Label Switching (GMPLS) common control plane is believed to be a promising solution for the Next Generation Optical Internet. In this scenario, Multi-layer Traffic Engineering (MTE) can be improved in terms of transmission qual-ity and traffic grooming. This paper proposes an integrated MTE scheme able to route IP traffic considering the potential power pen-alty of all-optical connections (for transmission quality purpose) and the network resource usage (for grooming purpose). The routing algorithm is executed on an integrated graph formed by both the physical and the logical topologies. This graph representation en-ables integrated Resource Reservation Protocol (RSVP) sessions that decrease the latency time. Via extensive simulations, the per-formance of this scheme in terms of connection requests success probability, resource usage and transmission quality is evaluated
