Enabling subwavelength level traffic grooming in survivable WDM optical network design

The explosion of data traffic and the availability of huge bandwidth using WDM optical network make it important to study optical layer networking restoration design. This paper addresses problem of enabling traffic grooming in mesh survivable WDM optical network design. Traffic grooming in optical network is defined as the act of multiplexing, demultiplexing and switching lower rate traffic onto high capacity lightpaths. The path selection and wavelength assignment schemes are formulated as integer linear programming (ILP) optimization problems. Two exact formulations are given for employing backup multiplexing and dedicated backup reservation with minimizing the total link-primary-sharing.
