ABSTRACT:
A system and method for minimizing blocking in optical networks utilizes algorithms developed to reduce non-revenue generating OEO conversions as a result of blocking based on routing and wavelength and/or subband assignment. Demands are prioritized on a basis of optical reach, and regenerators required for overcoming optical reach limitations are strategically placed to overcome blocking.
