Tree Reconfiguration without Lightpath Interruption in Wavelength Division Multiplexing Optical Networks with Limited Resources

Today, operators use reconfiguration to improve the performance of connection oriented networks. In our previous work, we studied tree reconfiguration without data flow interruption in wavelength division multiplexing optical networks. In our previous approach, the available resources of the network (wavelengths) are not considered as limited. In this work, we study tree reconfiguration in a network which has a limited number of wavelengths per link. This paper proposes an algorithm called TRwRC (Tree Reconfiguration with Resources Constraint). TRwRC reconfigures a tree without data flow interruption in a network with a limited number of wavelengths
