In certain networks deployment scenarios, service providers would like to keep all the existing MPLS functionalities in both MPLS and GMPLS network while reducing existing complexity.In this document, we propose to use the PCE as a central controller so that LSP can be calculated/signaled/initiated/downloaded/managed through a centralized PCE server to each network devices along the LSP path while leveraging the existing PCE technologies as much as possible. This draft describes the use cases for using the PCE as the central controller where LSPs are calculated/setup/initiated/downloaded/ maintained through extending the current PCE architectures and extending the PCEP.
