Optical Label Switched Path Design for Photonic MPLS Network

Abstract

The technological development about Photonic MLPS (Multi Protocol Label Switching) is progressing with advancement of optical communications technology. In this paper, we introduce about the design technology of Photonic MPLS networks. The target networks here are based on WDM(Wavelength Division Multiplexing) networks. Since the routers which have wavelength change function, and the routers which don't have are intermingled in these networks, the existing designing method of WDM network is inapplicable. Then, we explain in detail about the OLSP designing method in these Photonic MPLS networks.
