Current View of Optical Internets
Big Carrier Optical Cloud using MPLS and IGP for management of wavelengths for provisioning, restoral and protection

OBGP Optical InternetsSame physical architecture – but different management and control
Big Carrier Optical Cloud disappears other than provisioning of dumb switches where optical cross connects is controlled
by customer at the edge
Customer is now responsible for wavelength
configuration, restoral and protection
