Minimizing SONET Add‐Drop Multiplexers in optical UPSR networks using the minimum number of wavelengths

Abstract: In SONET/WDM optical networks, a high-speed wavelength channel is usually shared by multiplexed low-rate network traffic demands. The multiplexing is known as traffic grooming and carried out by SONET Add-Drop Multiplexers (SADM). The maximum number of low-rate traffic demands that can be multiplexed into one wavelength is called the grooming factor. Because SADMs are expensive network devices, a key optimization problem in optical network design is to groom a given set of low-rate traffic demands such that th… Show more
