摘要：

In this paper, an enhancement to the novel G eographic Midpoint (G MP) routing algorithm is introduced. The proposed enhancement improves the original algorithm to be more efficient in providing the targeted route. This is done by producing a new midpoint for every iteration of the algorithm that adds more accuracy to the process. A number of direct applications like the solution of the Monitoring-Trail (mtrail) design, which is used in fault localization in optical networks, are illustrated. An introduction to the Routing and Wavelength Assignment (RWA) problem in Wavelength-Routed optical networks is presented as well as briefs of optical trails. A simulation of both the original and the modified algorithms is carried out and examples are provided for demonstration purposes. An optimal solution for the algorithms is also demonstrated for comparison.
