Intercarrier interdomain control plane for global optical networks

This paper presents the Photonic Interdomain Negotiator (PIN) as the secure global optical control plane architecture to interoperate multiple wavelength-routed network domains with incompatible local control planes. The PIN interdomain routing and wavelength assignment is characterized by constraint-based optical path-vector routing to determine end-to- end lightpath across multiple domains, and by conversion-aware wavelength discovery to resolve wavelength blocking during discovery phase. The PIN interdomain optical signaling is supported by the Robust Fast Optical Reservation Protocol (RFORP) to minimize reservation delay by employing parallel reservation processing in multiple domains along a domain-path, and to minimize wavelength blocking during reservation phase by employing localized rerouting.
