The provisioning of lightpaths in an IP-centric wavelength routed network requires a control
framework for the establishment and maintenance of optical virtual circuits. This framework should
consider scalable protocols required to handle the increasing network complexities/dimensionalities
and interact with IP routing and traffic policy management protocols . Moreover, as in conventional
IP networks, Optical Cross-Connects are to be considered IP addressable devices, capable of receive
and distribute information regarding the different performance parameters relevant to the optical
transport network. A self-contained protocol paradigm is no longer valid and co-operation is expected
between the upper network layers and the optical layer appended at the bottom of the protocol stack.
Hence, a novel Multiprotocol Lambda Switching control framework is proposed based on
conventional MPLS Traffic Engineering and QoS Routing using OSPF, thus migrating these concepts
into the optical domain.
