11. PAPADIMITRIOU Dimitri IETF 49th Meeting - San Diego Next Steps t Improve procedures (fault-tolerance, protection and restoration) t Enhance diversity-related flooding t Extensions for multi-wavelength connections t Add state-diagrams for signaling and topology & resource distribution mechanisms t Inter-domain routing extensions

12. PAPADIMITRIOU Dimitri IETF 49th Meeting - San Diego CONCLUSION t NNI signaling is required for G-LSPs spanning multi-carrier networks t Covers all different types of optical networks (e.g. SDH/Sonet, OXC, PXC based networks) t Compatible with G-MPLS paradigm Allows extending G-MPLS to multi-domain networks t Consistent with the work done at the OIF This should facilitate easy transition
