Applying saturated cut method for dynamic traffic grooming in IP/MPLS over WDM networks

One of the most important tasks for dynamic traffic grooming in IP/MPLS over WDM networks is to decide when and where to set up new lightpaths to provide bandwidth for the IP/MPLS layer. In this paper, we adapt the conventional saturated cut method to enhance the lightpath establishment capability of various traffic grooming policies proposed earlier. Heuristic modifications are also presented which provide almost the same level of performance with much lower complexity
