Abstract: Generalized Multi-Protocol Label Switching (GMPLS) is growing in popularity as a set of protocols for provisioning and managing core optical networks. In this paper, [note: A preliminary version of this paper appeared in the proceedings of CIT 2003, Bhubaneshwar, India.] we present new schemes for provisioning lightpaths in WDM optical network. We first propose a path selection scheme required for deploying lightpaths in GMPLS environment. When a request for lightpath arrives at a source LSR, in GMPLS it is required to send request messages from an upstream LSR to the downstream LSR for setting up a lightpath. Therefore it is needed that an appropriate route be selected through the optical network for the requested lightpath. Keeping in mind its signaling characteristics we describe a path selection algorithm that can be built on GMPLS to enhance its performance. We next propose a path setup scheme for setting up the connection using the path selected with our earlier scheme. The looka...
