ABSTRACT:
A method and apparatus for an optical reroutable redundancy scheme. According to one embodiment of the invention, a wavelength division multiplexing optical network includes a number of nodes each having an optical cross connect and each having stored therein a database representing conversion free connectivity from that node to others of the nodes. In addition, each of the nodes employs a source based scheme with the database to provision optical circuits in real time and an optical reroutable redundancy scheme.
