• ODIN (Optical Dynamic Intelligent Signaling)
  Mechanism
• TeraAPI
• THOR (TeraScale High Performance Optical Resource
  Regulator)
• GMPLS (Generalized Multi-Protocol Label
  Switching)
• Extends MPLS control plane to enable resource
  discovery, routing and lambda controls an
  all-optical networking environment.
• Inter-domain Intelligent Signaling

  Interface) to encapsulate logical label-switched
  paths within a lightpath.
• Future Implementations

3. User-Empowered Ad-hoc Sharing Objectives

• User-Empowered Ad-hoc Sharing
• Users own, control and manage lightpath objects
  (fibers, lambdas, optical cross-connects, etc.).
• Enable users or organizations to advertise
  portions or all of their lightpath objects to
  other users when not in use.
• Distributed Control Plane over Lightpath Objects
• Enables rapid sharing and provisioning of
  lightpath objects across multiple independent
  management domains.
• Enable dynamic configuration of optical-VPN.
• Object Oriented Networking Architecture
• Object Model defines how lightpath objects are
  distributed across a heterogeneous environment.
• Reference Model defines interactions among
  lightpath objects.
