With the rapid process on Internet and requirement for multi-services

Traffic Engineering （TE） is required to provide the core optical network with resource optimization and Quality of Service （QoS） for specific users. This article introduces MPLS TE for Internet

and on basis of that concentrates on how to realize TE control on optical nodes throughout the network

with GMPLS control plane. A relationship model for GMPLS TE control modules and an architecture model for intelligent optical network based on GMPLS TE control plane are raised.
