MPLS application to optical cross-connect using wavelength as a label
US7031607 Patents
A label Switching routing protocol for establishing a data path as a sequence of locally unique labels in an optical communications network, is provided. A wavelength on an optical cross-connect is considered as a label, or one portion of a label. Timeslots may be assigned to designated wave lengths so as to form the second portion of a composite label. An optical/time cross-connect (OTXC) capable of wave length conversion from an input to an output interface creates the datapath based on wavelength to wavelength substitution, under the control of a multi-protocol label switching (MPLS) protoc
