摘要：
This paper addresses optimal multicast wavelength assignment problem in WDM network with limited-range wavelength conversions (LWC). The optimal object of the problem is to minimize total number of LWCs required. We introduce the distortion constraint, which requires that the number of needed converters along the path from multicast source node to any member cannot be larger than the specified value. We solve the problem exactly by dynamic programming under session blocking policy and destination blocking policy, and present the experimental results.
