Abstract: This paper proposes a new scheme for Multi-layer Traffic Engineering (MTE) in Generalized Multi-Protocol Label Switching (GMPLS) IP over Optical Networks. The scheme routes IP traffic guaranteeing sufficient bandwidth, high trans-mission quality and low resource usage. The routing decision is made via a cost metric which considers lightpath's power penal-ty and propagation delay and number of available wavelengths and transmitters. The requests are accommodated on mixed (lambda and packet) GMPLS Label Switched Paths (LSPs) in-stalled by nested RSVP-TE sessions. Extensive simulations dem-onstrate the good quality of the scheme's performance in terms of blocking probability and resource usage.
