%X This paper proposes a dynamic routing optimal model in IP over WDM optical networks,on which the layered graph is based and the cost of total lightpaths could be minimized.Therefore,a corresponding on-line integrated rou- ting algorithm minimizing the Cost of Total Lightpaths(MCTLP)is designed accordingly.MCTLP optimizes the net- work resource utilization by integrally assigning bandwidth allocations on both IP logic layer and wavelength links usage on WDM optical physical layer.The performance comparison of MCTLP with two representative routing algorithms used in IP over WDM networks via simulation shows that MCTLP can use less links on IP logic layer and WDM physi- cal layer to carry IP traffic flows,resulting in accepting more connection requests and reducing the traffic blocking probability efficiently.
