Optimal Multicast Wavelength Assignment Algorithm for Limited-Range Wavelength Conversion
波长转换受限条件下的最优组播波长分配算法

Optimal multicast wavelength assignment problem in all-optical network with limited-range wavelength conversions is addressed.Given the multicast request,the optimal object of the problem is to minimize total number of converters required.In wavelength assignment,the distortion constraint is introduced,which requires that the number of needed converters along the path from multicast source node to any member cannot be larger than specified value.The problem is solved exactly using dynamic programming under session blocking policy and destination blocking policy,and the experimental results are presented.
